Colored Fluorescent

Hi there, My first time posting here, but have been reading the website for a long time. Recently I have been fascinated with lights and light art. I have been a fan of Dan Flavin for awhile and love the way he uses fluorescent lights.  One question I have is, how do I achieve colored fluorescent lights? I have done a bit of research and a few people have suggested cellophane wrapped tubes, but I'm concerned that this might burn / melt, and may look slightly amateur?  Any help would be much appreciated. I have attached a couple of examples below. L

Fluorescent Lamp

Here is an art project from some designers that I came across and have been trying to reverse engineer. If anyone has any idea's on how to power and connect the fluorescent tube it would be greatly appreciated! Here is a description from the web:  Design duo Mischer’Traxler, Wien | Austria, started their project to focus on light sources and came up with the idea to combine two lamps into one. This way they created a new design that uses a energy-efficient fluorescent tube bulb and gives the lamps a whole new character. The name of this lamp is ‘Relumine‘ and plays on the fact that we all have to switch from old light bulbs to new energy saving light sources. The fun and challenge is to combine different type of lamps, like a hanging pendant with a floor lamp, a floor lamp with a desk lamp or different heights and hardware. Each Relumine uses two, discarded lamps, which are disassembled, sanded, newly lacquered and adapted with newer technology, before they are connected by a glass tube which holds the fluorescent tube. Together these two lamps need less energy than each one in its previous life.

Help with T5 Fluorescent Light

I'm adding a 9" T5 UV light to a small project I'm making. I found a cheap G6T5 Bulb and a Ballast but when I went to purchase the Sockets for it, I ran into a problem. The Bi-pin T5 sockets come in Shunted & Non Shunted and I have no idea which one I need. What is the difference and how would I tell which one to buy to finish my light? Once I have all this I'll have to figure out how to wire the thing. But first I need to know which sockets I need to buy. THANKS!!

CFL (compact fluorescent light)?

Hey everyone, Not too sure if this is the ideal place to post, if not please forgive me :) Basically, I want the spiral type CFL safely cleaned and emptied so I can use it. - I couldn't find a place selling 'recycled' ones or similar, I also dislike the idea of doing it myself and getting mercury all over me :(. I am thinking of contacting some manufacturers to see if they would sale me some defective ones that haven't been filled with nasty stuff :). Just wondering if anyone knew of a place where I can get them, hassle free. I'm a UK lad though, to make things harder :) any help much appreciated as always.

Something to block office lighting?

The office building where I work has a conference room that has 4 fluorescent light units, each measuring 28” by 44”.  The problem is, one of the four light units is an emergency unit, and is always turned on.  So when we want to show power point presentations, etc.  the room is never  fully dark.  With the 3 lights being off, it’s just barely dark enough, and it would be so much better not to have the light from the emergency unit.  Due to safety codes, turning off this light is not a realistic option for us.  So I was examining it today and was wondering if someone had an idea to construct some sort of temporary “cover” that we can quickly and securely place over this one light unit while we have our power point presentations?  The cover would have to be lightweight, secure (we would not want it to fall on any clients!), and I think made of some sort of fireproof material, in case someone forgets it’s up there and the heat from the florescent light tubes doesn’t cause any danger of fire.  Each light unit has this metal “grid” that I guess is meant to reflect and disperse the light in an efficient way.  This “grid” is made up of smooth 1/8” metal strips, which create 24 empty space “cells”. The inside of the cells measures 7”X5.5” and is 2.75” deep.  There is a small clearance between this metal grid and the fluorescent tube lights.  And the light unit is 10 feet off the ground. Any suggestions??  Thanks!

Help upgrading CFL circuit? Want to drive cfl's up to 25w.

Hello I have built this circuit, it can drive cfl's up to 15w, how do i modify it so that it can drive cfl's up to 25w?  I am using D313 for his project as the D882 didn't gave me the results i needed. Using 12v battery. Here is the original instructable link (This question is optional) Do u think the transformer i made for this circuit can be used for the famous Jeanna's light (Joule's Thief). If yes then how it would connect on the circuit? I will be making two or three more transformers like this. Do u think it needs modifications for its working like number of turns for the primary, secondary and feedback, different wire gauge?

How to make florescent ink?

I have Googled and searched Wiki on how to make fluorescent (ultraviolet) inks. I want to know how to make them. I dont want th lemon juice , corn starch, milk or other types of invisible inks. I want to make the stuff the glows under uv light. I searched using uv, ultraviolet, fluorescent inks but couldnt find anything other than the lemon juice and other types of "invisible" writing. Please help if you know where to find or if you know how to make fluorescent (ultraviolet) inks. You can email me at I mean the inks that u can buy for handstampers and that are put in invisible ink markers. I want to make the stuff myself and not have to buy it off the internet.... So while yes there are alot of things that glow under UV, I want it in liquid form.

Glowy Umbrella

I had an idea today I thought would be interesting after reading about this - - how about integrating a fluorescent tube into the handle of an umbrella. If the tube was supported inside an acrylic clear (or coloured) tube and had some kind of connection to the handle and to the tip of the umbrella, then when walking under pylons, in a storm (eek?!), or in any situation where there would be a big potential difference between something above the user and earth. This could be interesting near tram/train lines.What do people think?

Fluorescent Plants

Recently I presented a science teacher in my school, Mr. Zhang with the idea of growing plants with tonic water which contains quinine to see if they would glow under a black light. Today we saw that these bean sprouts had defused and taken in the tonic water, as a result the bean sprouts were fluorescent under the black light. I first chose the mung bean / bean sprout because I know that bean sprouts are translucent and it would be easier to see the glow, but now I want to find out if the seed will take in the quinine, and if so would the quinine be in the flesh of the plant at all. Another test that Mr. Zhang and I were considering was to use a tonic water in a hydroponic system to see if the plants utilize the quinine. Dr. Paul Williams suggested that I grow fastplants in the dark, because their stem is translucent is grown in the dark. (Mr. Zhang knew him from a workshop he did involving fastplants) I'll be updating this as I continue the study, I'll start growing very soon, as soon as I order the supplies that are necessary. The picture below, is of two mung beans, the one on the left took in the quinine, and the one of the right is normal.

Laptop LCD Cold Cathode re-use

So recently, an old laptop of mine died. It was an old dinosaur of a laptop, slowly running down the remaining years of its life. Then it died. So sad. To honor its death I dismantled it. I got an interesting motherboard, some decent speakers, a 5gb harddrive along with a floppy and disk drive. What really interested me the most though is the LCD screen. At first I hoped that I could re-used the screen as a tertiary screen for my desktop, but later I realized the near-impossibility of this task and gave it up. Instead I chose to take the screen apart for its cold cathode lamp. It's almost 12 inches in length, and very thin. Before the motherboard died, the LCD back light was still working. So I wanted to take it out, along with its inverter, to attempt to re-use it. Soon after doing this I saw a problem in my plans: the input of the inverter is a whopping nine wires. This is a bit more than I'm used to dealing with for power supplies. I was wondering if you guys knew any way that I could go around this? At request I can most more pictures and model number of the inverter in case you can't read it in the photo. tl;dr - Cold cathode inverter in picture. output is two wires, input 9 wires. How do I use this

Flourscent Light Sickness

Every time I walk into Wal-Mart or Home Depot, I get sick because of the fluorescent light. The problem is, almost every large retailer uses fluorescent lighting. I get migraines, and queasiness. It has a great impact on my life. I was only curious to see if anyone else on instructables had such a sickness. If you do have such a sickness, what Do you do about it? My new school has all fluorescent lighting. -sunglasses? -migraine medication? (although that would not do much for the sick to the stomach feeling) I call it Wal-Mart sickness.

Fluorescent-tube digital clock

I'm thinking around building a massive digital clock with fluorescent tubes.Starting with a basic digital clock, the output to LED segments would be put through transistors, to 12v relays, acting upon the mains feed to the tubes.However, some segments will be on more than they are off. I'd rather have the relays using power to switch to the less frequently used position, but I can't find an easy way to figure-out which segments spend more time off than on (and vice versa).any ideas?Did some calculations to produce the graphs. Based upon 4W tubes, surely the smallest available?) and 12V 50mA relays.

UV Surface Mount LEDs

I am currently modifying an iBook G3 so that, among other things, it will be fluorescent orange. Currently, when the computer sleeps, a white LED illuminates through the casing. Since the casing will now be fluorescent, I would like to replace the white surface mount LED with an ultraviolet one, so that the case will glow as the computer is sleeping. I was wondering if someone could help me out by telling me where I might be able to purchase an ultraviolet surface mount LED? P.S. The image included will be stenciled and mirrored on each side of the apple on the top of the iBook.

CFL Recycling at Home Depot

CFLs (compact fluorescent light bulbs) are becoming increasingly popular: right from the article linked to below, "compact fluorescents use up to 75 percent less energy, last longer and cost less over time than incandescent bulbs." Plus, they come in a fun, curly-q shape.However, they contain trace amounts of mercury, which makes recycling of them difficult--until now. Home Depot (which, to my surprise, is the second-largest retail company in the United States behind Wal-Mart) is offering comprehensive recycling for CFLs: any brand, at any of the nearly 2,000 Home Depot locations.

Find/make frosted glass/plastic tubing

I'm building an audio vu meter, and thought the LEDs would look nice enclosed in some frosted tubing, but I'm having trouble finding any. Something like a fluorescent tube would be perfect, but the coating on the inside of them rubs off fairly easily (is it phosphorous based?), and cutting these things open isn't usually recommended (they have small quantities of mercury in, I believe). It's easy enough to find perspex tubing on ebay, but it's all clear - I really want something translucent, so that the LEDs give a glow of light, rather than a point. Is there something I can coat glass or perspex with to create this effect? Or am I searching for the wrong words? I sometimes see the fluorescent tubes referred to having a satin finish, but that hasn't helped

Eco-conscious: Compact Fluorescents

My friend Rawhide did a decent bit of research into the best type of compact fluorescent lightbulb, so I'm sharing is findings here. Do you have anything to add?Rawhide on compact fluorescents:In all my web searching I couldn't find a truly exhaustive comparison on lightbulb stats. Even, which was the most comprehensive, didn't list the CRI for all of its bulbs. What I did realize was that the "bright white" bulbs I bought from Home Depot were of the wrong color temperature to mix with incandescents and that is why they looked so cold. I also found a couple of people who really liked N:Vision, the Home Depot brand.So I decided to give Home Depot another shot and exchanged the bright whites for soft whites. Curiously, when I went back the CF bulbs had a big display that wasn't there the week before with the bulbs I wanted in $9 4-packs, which was much cheaper than the individual bulbs.I replaced all the bulbs in our living room and dining room and I (and the nameless other) find the light quality to be quite good---it wasn't possible to distinguish the CF from the incandecent bulbs once they warmed up. If you look at the light in the room as a whole, there is the slightest bit of 'vibration', but it's really not noticable unless you're looking for it.Net savings: 600W->140W to light the two rooms. Awesome.Finally, as a coda to my quest for compact flourescents, I learned that Massachusetts is offering a $2 rebate per package for Energy Star lights and that Home Depot also sells 6-packs for $10. So, you can get 60w replacement bulbs for $1.30 rather than $4 or $5 you sometimes see. Retailers need to supply the coupons, which are instant rebates at the register. There are also bigger rebates, like $75 off a dryer and $20 off a torchiere light fixture.

LED Lights don't attract bugs

Microwave Oven Transformer Stack

This is my Microwave Oven Transformer stack. It is currently current limited using a heater. There is approximately 10 36 watt 4' fluorescent tubes in a string around my garage that I am lighting with the MOT stack .My MOT stack contains 4 Microwave Oven Transformers connected with their outputs in series and their inputs in parallel. They are mounted on plastic cutting boards. I am using threaded rod to hold the layers in place while the PVC pipe covers the threaded rod and it also supports some of the weight. The output of this is approximately 8800VAC at 350mA The Input voltage is 240VAC Thanks for looking, Please comment and remember to rate if you like it! Just say if you want any pics of a certain thing, e.g. the MOT stack arcing to wood/metal etc. (I will try to get more pics of it arcing soon but it is hard to use a camera that has like a second delay before it takes the actual pic from when you press the button, stupid camera) ********************************************************************************************************** Edit The new pictures are of an arc between two carbon electrodes. The other pictures are of 12 fluorescent tubes connected in series but arranged in parallel so you can see them all

Orchid Care Questions

So I have been given this orchid - in bloom... I really don't know how to care for it.... right now, it's been on my kitchen bar for about a week getting fluorescent light. My father grows a bunch of orchids at home, but he just sort of "plants" them somewhere an forgets about them - which has worked very well for him :p Any care recommendations? Is there anything particularly wrong with cutting the flower stem off (if no, where should I cut)? I do have a balcony, it faces North and the plant is in a plastic pot (maybe 1.5 quart size) with wood chip mulch. thanks :)

Seeing Auras & Ghosts

I have posted this on other forums without much response. Since some of the best minds use this site, I should get a lively response. Friday, on a TV show called 20/20, they interview some kids that said they see auras and spirits. Do any of you know people who can do that? I have tried to see or photograph auras without success. It seems that these things may be visible either in the ultraviolet or far infrared and require someone with eyes that are more sensitive to these wavelengths. Young kids would be better at that. Infrared and ultraviolet light (UV) are in our environment, even though we can't see it. You would expect that different people would look different under UV, just as they do under visible light. Additionally, some things show fluorescence under UV. Perhaps auras are differing fluorescence by individuals as seen by those with extended visual response. It might be interesting to look at various people under just UV or just infrared (perhaps using night goggles) and note the observations. It would be interesting to have someone view auras through various filters to see how the auras change. Are auras affected by magnetic fields? Would smoke in the air have an effect? Does the aura look better with a dark background? Does getting drunk help? Ghosts are probably more difficult. It is to be expected that God doesn't want us asking them sensitive questions (like "Where's Heaven?"). ~Bob~

An illuminated light switch that will work on 120/240V AC.

I have a fluorescent light fixture that my dad gave me, it was about 9 feet, so I cut it in half and re-did the wiring so it would fit on my workbench. It uses a plug to turn on and off. I know the wall switches they sell at home depot are rated for 120/240v but they are cheesy looking and hard to locate in the middle of the night in my garage. When I come home from work on my motorcycle, I need an immediate source of light. Is it possible to use an illuminated switch, say from, Oreilly's or Advanced Auto parts and add some form of surge protection so it won't blow or pop a breaker? I want to use the same concept as a surge protector, it uses an illuminated switch, but only cause its components are protected by the surge. Is it possible to make my own involving soldering components on PCB?

Flood Blacklight?

I know there is already some similar posts but i couldnt find anything relating specifically like this. I got a flood light with the intention of turning it into a flood black light. I want to light up a basketball court sized room using 4 at most. I have a few questions: 1) Is there any way to add anything to the front to turn this in to a black light (Don't need it to be UV rays as I know it's not likely. I just want it to make things fluoresce when it shines on them)? I'm looking at doing something similar to the sharpie black light hack. 2) This light puts good clear light for more the 40 yards. If there were a way to mod it into a black light, how much will it affect the range of good light? 3) Is there any way to connect the lighting to a battery pack or some sort of regular 3 pronged plug?

incandescent light flicker hacks

There are 2 hacks with incandescent lights that make flickering effect. may be usefull for some haloween stuff here is the most basic description. if you build it be carefull in fire safety - some stuff may overheat and blast / catch fire. use non flammable boxes if needed. starters and diodes may explode if connected incorrectly - always protect your eyes do not do any of the hacks with CFLs - they are for incandescents only. they may work with LED lights depending on other components in the ciruit and the amount of current (if there are capacitor / induction / electronics / transformer in the LED circuit then dont do it) hack 1 - slow flicker (i saw it somewhere on instructables before) connect the incan in series with fluorescent lamp starter (the neon discharge type) you may connect 2 starters in series. i'd expect longer outages this way. if they dont light (not enough voltage) then use the starters designed for 2 x 18 W fluorescents. warnings dont connect the starter (or series of 2 or more starters) directly across the ac source. the starters will blow immediately and may explode. check that in any possible path through the starters there is an incan light dont connect stuff in parallel unless you really know what you do. lights connected in parallel take the sum of the currents they take on their own - anything more than 1 light is too much for a starter (or any amount of starters in series - each gets all the current) part 2 - fast 50 Hz flicker connect the lamp in series with an 1N4007 diode. the diode blocks 1/2 of the ac wave and makes some light flicker. seen best in low watt lamps with thinner filament (with less thermal capacity) diode may be used together with starter to combine the effects this hack is used widely in heating appliances that have 2 heat settings. in the lower one they are connected thru a diode

Convert DC Light bar to AC

I'm trying to help out a friend. He's an animation student and he frequently has to use a light box while he's sketching. For those unfamiliar, he draws on a paper, and then puts another paper on top and traces it again, but with a slight change from the first. This process continues over and over until the animation is complete. In order to be able to trace, he's got a piece of white plexi (with a 90° bend in it) as his "table". He then places an off the shelf Energizer "Under Cabinet Light" under the plexi. This light has a fluorescent bulb and is powered by 8 AA batteries. Simple calculations means it's running on a 12V battery pack. Since he's often doing homework for 6 hours straight, the 8AA batteries become costly and the light dims over time. He was asking if I could hack the light to take AC power instead. I have an old wallward ac adapter that has these specs: Input: 120VAC 60Hz 30W Output: 12V @ 1.2A. I also took pictures of the circuit board I found inside the light. While I can't distinguish exactly what's on the board, I can pick out a capacitor, a transformer and some sort of regulator. I should've  got a quick schematic... from the looks my google searching, it's a simple fluorescent lamp circuit. Would it be as simple as stripping the ends of the AC adapter and soldering it to the positive and negative contacts on the light bar's circuit board? The adapter itself takes AC and makes it DC so it should work right? Another thing he is thinking of is having me swap out the tube for LED's. I'll just need an LED driver and I can use the same power supply I found in my junk box... it's just a question if the high powered LEDs would be bright enough. Surely if the tube is bright enough on fresh AA batteries, 3 high powered white LEDs would be brighter right? Also he's on a budget, so the AC/DC hack would essentially free for him!

I have acquired, as a strict one-off, a quantity of solar cells.Apparently seconds that "work fine", the one I have unpacked is about 5 inches electrode-to-electrode, glass, and produces about 4-5V with no load in full sunlight. I assume the others are similar.A plan springs to mind. A plan to save money and be "greener". I want to use them to charge batteries during the day, then light my home with LED sources.A grand scheme, one that still requires the approval of She Who Must Be Obeyed, so I intent to take it is stages.Stage One: The Shed.I plan to install an LED light source, running off a battery charged by cells stuck to translucent panels already in my wall.Questions:what number and combination of (ordinary, cheap) LEDs would give a reasonable match for the brightness and colour of the currently-fitted 3-foot fluorescent tube?Is this a suitable circuit to charge the battery?Should I connect PV cells in series or parallel?Is there anything I should have thought of?

Get electromagnetic pulses from a gas igniter

Hi, here I have a common gas igniter like this: Well, I removed the circuit from the box, then I shorted the two terminals, using various kind of coils (thick wire, thin wire, in various configurations and with different turns), but seems that this circuit is unable to generate electromagnetic pulses; I've tried to turn on a fluorescent lamp, to cause interferences to a pocket calculator (as I can see in various videos on youtube), but nothing happens. If I remove the coil from the terminals I am able to get nice sparks. So, why this circuit won't work as expected? I miss something? However this is the circuit: Please note that I'm aware of the fact that these kind of circuit could be dangerous; I'm taking all possible precautions (I'm using it far from any electrical device, I'm using isolated gloves, and so on). I just want to make this circuit for fun. Many thanks.

Make your own 3d Renderings

OK here is my proposal take: 1 machine 900, 000 concept + 2 existing instructables + common materialsa 3d scanning system Here is the concept please see it and come back: if u already saw it, in a nutshell they use 2 different forms of light but no laser BUT in these 2 instructables they do So, If we used an Amalgam of both plus:UV led's6 CHEAP webcams (x y and z )fluorescent paint We could obtain:A 3 d scanner for common objects that uses no lasers but the light sources in the demo (or even people perhaps not for animation but for other purposes) Those who did not get lost in the explanation: please contribute!Note for negative typists: Yes it is an adaptation and and I am asking for brainstorming yes, my explanations are terrible yes, yes, yes to all your negative comments.Note for those positive contributors: I will not ignore you at all please add your ideas!

Brighter headlights?

Hey all! I drive a 1984 BMW 318i (that's the E30) with the standard H1 bulbs for the low and high beams (4 x H1 in total). I want better visibility at night and have been looking at options. Can anyone help with the following: 1. do i have to use high wattage bulbs to see a significant difference or would "upto 90% more light" 55W osram bulbs help? I would hate to spend the money on the 55W osrams only to end up with 5 extra lumens. 2. am i correct in saying that ALL xenon bulbs require the whole ballast and starter setup like fluorescents? are there some that don't? 3. Is there anyone who has used a high wattage bulb? what are your experiences? is the shorter life worth it? where on the continuum of wattage VS lifespan would you recommend? Right now I'm leaning towards the high wattage option, something like 80-100W. MY local hardware doesn't stock these and I doubt my local auto-electrical supplier would either. I'm thinking I may have to do some digging, maybe 4x4 accessory stores would have them since they are technically only meant for offroad use. K thanks, your help is much appreciated, I'll try to post an 'ible of old VS new and the installation procedure once I decide on the bulbs.

Undercabinet LED lights from 110v source

Hello, Ever since i moved into my current home I have wanted to put in under-cabinet lights in the kitchen. Its a small kitchen but the current fluorescent lights are just not giving me the light I'd like.  Powering the LEDs is my only concern. There are two under-cabinet areas each with one type of florescent light fixture with a normal 110v power line running into each light directly from a small hole in the wall (all hidden of course under the cabinets). There is no power outlet associated with these two lights. There is one outlet along the wall but I would not like to use this if possible as it powers the kitchen appliances, and it would show the power cord from the lights (Id love for these new LEDs to remain hidden.) I understand to use a 110v source I would need a LED transformer of some kind, I have seen these for sale, but I do not have an outlet that this transformer can plug into. Like this: Is there a way to connect a type of transformer to this direct 110v line? Would I splice the plug off the end of the transformer and just crimp it to the 110v source from the wall?  Like the end of this transformer: Im currently at work but if pictures help I can upload them later. Thanks!
