Battle of the Bulbs!

Whilst looking through the recent -ibles i saw CYNICALifornia's variation to the light bulb lamp. Running, er, clicking as fast as I could, I got to the home page and saw that his -ible was featured as well, as I scanned the page I saw, parallel to his, My -ible! IT'S ON!!! not really, I just thought it was funny that they were both featured, almost the same -ible, and right next to each other..

Light Bulb Lamps

Oh what to do with the light bulb now that you're basking in the efficient glow of your CFLs? Well, you could convert them into these light bulb lamps as Sergio Silva has done. It's a pretty sweet item with neodymium magnets holding them in place on an included acrylic plate with embedded bits of steel.However, the price tag is $650 for the set which is pretty flippin' ridiculous for what can be remade with scrap and $10 of materials, if that. To be fair, the light bulbs Silva makes are sturdier than the regular item, are all made by the original artist, and are limited to a run of 66. So you're buying some design-y street cred before they get knocked off and sold for one-tenth the price. Linkvia bbgadgets

Fish In A Light Bulb

So I was wondering do you think it would be possible to take an old ligth bulb hallow it out and use it as a fish bowl for a mini fish?  Im just not sure should I put a small plant in there and if so what kind of plant so maybe just a little air pump while Im gone.  Or would a small fish be fine if I put some rocks on the bottom and then just changed it once a month or so?  Or would it end up being every day do you think? Ethan PS I hope people dont bite my head off thinking Im a horrible person I just like the idea of having a fish in a light bulb I think it would look cool so Im asking before I do it and accidentally kill a fish...

midflex idea bulb

I was in my quantum class today taking in some nice Schrodinger equations. The professor was having a hard time figuring out which students were understanding the material. I thought to myself, "Wouldn't it be nice to have a consistent way to show the teacher you understood." So then it hit me... why not have a classic idea bulb on top of a hat. You could push a button and it would light up. Thus indicating to the teacher that you understood the material. Simple enough, but kind of annoying to push a button every could of minutes. Why not use the new Mindflex toy to gauge your understanding of the material? The user could wear the headset like usual. Instead of controlling a ball like in the game, a sudden decrease in concentration (the realization of an idea) would turn the light bulb on. The electronics should be simple enough. It would obviously be better to use an LED instead of an actual light bulb. I would build it myself, but I don't want to spend $60 on a mindflex game. What do you think? Elijah

Fluorescent bulb questions ? Answered

Hello, Short question but sorry,  I cannot seem to shorten it; the actual question is in the last two lines . My friend's outside light stopped working; Earlier today I was asked to replace the two bulbs; they had stopped working and seemed slightly brown on the ceramic part. They are four pin fluorescents; I have not used these type before. I went to Screwfix and their catalogue showed two bulbs that looked identical to the original but one model said for electronic ballast only and one type said for magnetic ballast only; the shop staff did not know what a ballast was and could not advise me, when looking at the original, which type to buy. I went to Toolstation , no such distinction was made in their catalogue; I asked the guy about the ballast suitability; he did not know what a ballast was; I bought the one that seemed the closest in name. I have never has to think about ballast types before buying a bulb before; but after buying the bulbs I found a sticker on the lamp saying -electronic ballast. I stuck the first bulb in, it did not light. I put the bulb, instead, into the next socket; it lit and stayed lit. I put the remaining bulb in the first socket and both bulbs stopped working; whatever combination that I tried. The original bulb was an Osram Dulux D/E 26w/840 The  new bulb is a  sylvania lynx-de superia 26w 840  G24q-3 Technical Details Brand Sylvania Item Weight 9 g Product Dimensions 16.6 x 3.6 x 3.6 cm Item model number 25927 Part Number 0025927 Colour Cool White Shape Stick Maximum Compatible Wattage 26 watts Voltage 240 volts Specific Uses General purpose Batteries Included? No Type of Bulb Compact Fluorescent Light (CFL) Cap Type G24q EU Energy Efficiency Label A Luminous Flux 1800 lumen Wattage 26 watts Wattage 26 watts Bulb Features Low energy plug-in compact lamp Colour Temperature 4000 Kelvin Colour Rendering Index (CRI) 85 Average Life 10000 hours Average Life 15000 hours Bulb Length 167 millimetres Warm Up Time 30 seconds Lumen Maintenance Factor at the End of Life 95 I still do not know if it was the correct bulb or not but . . . Here are the questions:   Are some bulbs suitable for both types of ballast ? What happens if you put the wrong type in; does it just not work; or does it blow the bulb; or/and does it damage the lamp? Thank you

Bulb problems on iped?

I have an iped electric moped with pedals which I believe has a in hub motor ( haven't looked yet) the problem I have is this the replacement bulbs are almost impossible to find The headlight for example is a 55volt 36/36 which I am finding impossible to find  the rear brake light is 55 volt 15/15 watt unsure of the wedge bulb parking light which is 5mm width and there is definitely no 55 volt wedge bulbs this size The only conclusion I can think of is to insert a dc converter which will drop the voltage to each bulb from 55v to 12v giving me more availability on bulb selection I am just curious if any one on hear knows where I can get 55volt bulbs ?

Inverter to Flaslight bulb?

I am building a basic night light ordeal, and I used a photoresistor to detect the change in light. Of course, the photoresistor will, by default, only have a high output when there is light, so I used an inverter (Not Gate). My inverter is made up of a transistor , a 1.5k resistor, a 10k resistor, and leads off to a LED. The photoresistor would go off to the Base of the transistor, so it can invert the output. Originally, I had this hooked up to a 4.5 volt input (the photoresistor has 4.5 volts going to it, and the transistor had 4.5 volts going into it), but I wanted to brighten it up, so I upped the voltage to 7.5 volts so I could add a 6.3V Incandescent Flashlight Bulb (http://www.radioshack.com/product/index.jsp?productId=2102809). When I hook this up to a regular 6 volt battery pack, I easily turn the light on. When I connect it to the inverter, however, I don't get anything going on. I've upped the input voltages to 9 Volts, but still, no dice. Everything works fine until I change the LEDs to the bulb. So far, I've changed the resistor values in both directions (I've decreased them down to 10 Ohms, and increased them to a max of 1M Ohms). The only way I can possibly get this to work is by removing the Resistor going to the Collector, but then it is constantly on. The output of the photoresistor no longer matters. The output of the inverter is constantly high. Any ideas? All help is appreciated.

DIY Projector bulb problem ?

In reading some of the instructables on DIY projector lamp replacements I decided to give it a shot. So I purchased a Proxima Ultralight LX1 off of ebay, and when it arrived it contained no previous bulb, so I purchased a MR16 style 100 watt halogen bulb and installed it (with a seperate power supply). When I started it up and connected it to my laptop it worked fine for about a minute or so (give or take) but then the image went blank (not the bulb but the LCD screens showed blackness) for five seconds, then the image popped up as nothing had ever happened. I have tried everything to prevent this, other computers, killing the ballast (which is quite easy, only one wire to disconnect) different video sources and no dice. But I do know that it has nothing to do with the light bulb because it is on a completley different power supply and is not connected electronically to the projector in any way, there is something wrong with the controls of the unit Any Help would be appreciated, Thanks Bwpatton1

LED Lamp Buzzing (not a bulb)

About a year ago, I came across this LED lamp that was on sale at my local Target store. It caught my eye because it had a little tray at the base of the lamp along with a USB port for charging my devices. Since the first time I plugged it in and turned it on, it makes a buzzing noise. At first it didn't bother me, but now that I am spending more time at my workbench it has become annoying. I understand it is kind of common for LED bulbs to do this because of the dimmer switch being outdated, however this lamp is not dimmable nor is it a "bulb" so to say. It's about 7-9 SMD LEDs on a circuit with a rocker switch. If it makes a difference, I do have my lamp plugged into a surge protector and don't have anything plugged into the USB port located at the base of the lamp. What can be done (other than throwing it away, of course) to stop the buzzing noise coming from the lamp? Thanks in advance!

Giant Hanging Light Bulb Lamp

I'm wanting to create a giant hanging light bulb lamp, similar to the ones I've uploaded, but I'm not really sure how I would go about doing it. I think I would make it out of plastic. So I would need to create a mold and then make two halves on a vacuum form, but I have no experience doing that. I'm not sure how I would make a mold of a giant light bulb, what materials to use and how to make it. I had thought about maybe cutting something out on a lathe but I don't have a lathe and it seems like it would have to be pretty big. I also thought about paper mache but I was afraid it might be too bumpy and light bulbs are smooth. Also once I have created the vacuum form plastic halves how I would attach them together with out having a large seam show.

Lighting has taken another step towards energy efficiency as Toshiba stopped making incandescent bulbs yesterday. It will now be focusing more on other lighting such as LEDs.
