Hello Does anyone have any idea how to create this effect. My understanding is that the bottle was diamond cut from the bottom and the electrons were fed in. My main questions are around the bulb. Is there anyway to get the same effect using LED lights? What if we were to arrange fiber optics wires in a spiral arrangement and shine an LED at the end. Would it work?

Bubbling LED Hanging Industrial lights???

There is a project I have been vigilantly searching for on instructables and google. I remember seeing it on here a couple of years ago and now cannot find it anywhere.. The project consisted of Industrial cage jar lights, LEDs, Vegetable oil, and a fish tank pump and some other supplies.. The LED lights would be submerged in the jars with vegetable oil and   the fish tank pump supplies air into the industrial lights and the oil bubbles..  I would love to find this project. I have been itching to find it for the past year or so. If anyone knows where to find this project, Please pm me.. I would appreciate it immensely.. Or if anyone knows where to find the Industrial cage lights i would appreciate any help in this matter.. Thanks..

Halogen to LED.?

Right now i'm working on photo spectrography, and using a halogen lamp because of the wavelength it outputs. The thing is, we are trying to make a more portable version of this, is there a type of LED or an array of them, that i could use for this? Take in mind that the LEDs have to output a wavelength very similar or equal to that of a halogen lamp.

LED Light Box

Normally, a light box uses fluorescent lamps (e.g. 36 watts Philips Lamp) and electronic ballasts to emit light. However, it consumes too much electricty and the life of lamps is short. Therefore, I would like to replace fluorescent lamps with LEDs.

Gravity Lamp, the LED lamp powered by gravity

A Virginia Tech student designed an LED lamp that is powered by gravity. It is called the Gravia, and it took second place at the Greener Gadgets competition in NYC. Gravity as a renewable energy source? Amazing!From http://pesn.com/2008/02/19/9500471_Gravity_Lamp/Concept illustrations of Gravia depict an acrylic column a little over four feet high. The entire column glows when activated. The electricity is generated by the slow fall of a mass that spins a rotor. The resulting energy powers 10 high-output LEDs that fire into the acrylic lens, creating a diffuse light. The operation is silent and the housing is elegant and cord free – completely independent of electrical infrastructure.The light output will be 600-800 lumens – roughly equal to a 40 watt incandescent bulb. Each drop of the gravity mechanism runs the light over a period of four hours.To "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. An hour-glass like mechanism is turned over and the weights are placed in the mass sled near the top of the lamp. The sled begins its gently glide back down and, within a few seconds, the LEDs come on and light the lamp, Moulton said. “It’s more complicated than flipping a switch but can be an acceptable, even enjoyable routine, like winding a beautiful clock or making good coffee,” he said.Moulton estimates that Gravia’s mechanisms will last more than 200 years, if used eight hours a day, 365 days a year.The winner of the Greener Gadgets competition was the Enerjar.

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!

A lamp from RGB LEDs

Hi, I'm want to build a lamp from 63 RGB LEDs. I want to be able to change the intensity of each color. Is there something in my schematics that should  be changed, for example do I even need the resistors after LEDs since I have the potentiometers. I think the values might need to be changed. The switches before resistors are to eliminate that color if the potentiometers won't do it. There should be also a main switch after the power supply.. Do I need anything else, so that it will work and to it will be safe? A bit offtopic, but if I would only use one color LEDs, would it be better to connect them to parallel or series?

Help making an LED lamp

Alright, I want to make an LED grow light for my plants because the window I want to put them in doesn't get enough sun. I need quite a bit of light for this application and it will have to be on for a significant part of every day so LED is a must. I've been looking at the prices and it seems like the most economical option is to buy some LEDs off ebay, buy a driver... maybe some resistors... then mock up some kind of heat sink to connect them to. I was considering about 10-20 ten watt on chip LEDs. This light is going to be in a room I'm in a lot so I don't want to go with any funky colors. I'd like to just use daylight spectrum LEDs. Something around 6500k. Anyway, I'm thinking it makes the most sense to get one big driver to run all the LEDs rather than one driver for each. That just seems cheaper and frankly more interesting. But I need help understanding how to wire the whole thing together and understanding whether I need resistors etc. So I'm looking for some general help figuring out what to buy and then how to wire it all together. Thanks :)

Are LEDS used in GROW LED LAMPS any different from regular, colored LEDs?

I've seen grow LED lamps for plants and flowers go for $100 to $200 on ebay and they look like simple red and blue LEDs in a lamp unit. These days anyone can do a lamp with LEDs since we have a wide variety of LEDs, drivers and casings at our disposal and at a very affordable price. Even if you add the cost of research and develpment and a healthy profit to remain in business into the cost of the device, I don't think the ratio cost-price of those lamps is fair. Those grow lamps seem to be a scam to me, unless the LEDs/drivers used on them are really more expensive than the widely available in the market. I am more inclined to think they priced their lamps artificially to cater to its intended market: deep-pocket obsessed gardeners, weed grow-op guys, fancy growers, etc. Why is that these lamps are that costly? What is the magic behind them or do they have "NASA" technology on them or what? Thanks for your input

I'm making a lamp...

Hello Instructables community! I'd like to make a desk lamp, and I'd like to plug it into a wall. Now here is my dilemma I have, the lamp would have 9 main lights inside glass globes and I'd like to have small little lights (like LEDs) around the outside like little points of light. Now in my experience LEDs aren't typically plugged into the 120V wall socket. I have a friend who's good with electronics who has tossed around LEDs, fiber optics, etc and it's all just mind boggling to me. He's even suggested using some kind of controller to make the small lights twinkle and I have no experience with that kind of thing. I'd appreciate if I could get some input as in what options I have for lighting this lamp. Right now it sounds like a valid idea is to use "super bright" LEDs for the 9 big lights and just regular LEDs for the multiple points of light around it.  I can provide as much additional details as needed. Thank you for any input.

Lamps from recycled parts, ideal example of a green theme.

Personally, i think this lamps look very cool, both items are made from various pieces of old electrical hardware.I love how the design is rather simple, but complicated by the parts used.Made by the Flickr user Qvidja50.He saysThe lamp on the left is fabricated from a railroad signal switching relay manufactured by the General Railway Signal Company in 1924. The perforated cylinders were originally ink canisters designed for high-speed fabric printing. The light on the right is made from a water-cooled dual processor from an Apple G5 desktop computer. Other elements include an hour meter, aircraft compass and 40W LED bulbs.Check out the full Flickr set.Personally, i like the 'hanging bulb' one. Firstly as i love the way the bulbs hang down, that and the use of a Powermac G5 heatsink is a win for an apple user fanboy like myself.For anyone looking to enter the Epilog laser cutter contest.

LEDs as a replacement?

I've been thinking, which, for me is strange. What's stranger, i've been thinking about saving the planet. I don't believe that global warming is solely the fault of man and his machines, nor do i believe that we're all going to fry in a ten-thousand year summer, but that's not the point of this forum, and i'd appreciate no comments labelling me as a communist, or a planet-hater. What i had in mind is a new system of lighting. Say i took some LEDs (lets say 16) and connected them in paralell, and attatched them to the appropriate power source, would they be more or less efficient than a tungsten filament lamp? As for aesthetic considerations, to simulate natural sunlight during winter months, one could add blue or yellow LEDs to tune the shade of the light. Would this idea be more efficient than the lights we have? (i avoided mentioning those energy-efficient lights because they're not really that efficient, and give crap light.)

water-based kinetic LED lamp

I want to mak a kinetic light using high-powered LEDs to produce glitter line through a thin layer of agitated turbulent water in a wall mounted shelf. So, this gives me a few questions, but let me start with the idea I've got. I want to seperate a shelving unit (preferably solid wood not particleboard with some decent HxDxW) into two compartments. A glass sheet would be slid into grooves onto the side supports. The upper portion of the shelving unit would then be wood, waterproofed with some thin styrene plastic sheets. The bottom would then be composed of a large aluminum sheet (recessed slightly upwards for astheatics) which would house several LEDs in addition to the power adapter and voltage regulator. This would likely follow the "powering high powered LED" tutorial's alternate power source to the pucks. At this point a small pump would be placed into the upper compartment along with just enough water to submerge the pump to a safe level. Perhaps a small recess would be included in the top to allow instant colour shifts by using stained clear plastic sheets (this would reduce total illumination, but these are to be mood/ambient accents not primary lighting source) to avoid any of the more expensive/complex colour shifting lamps. The big question I have at this point is how thermally safe this would be, and how much LED I would actually need to achieve decent brightness. Also, I would prefer if the bottom was modular enough I could remove and work on it without dissasembling the entire assembly, but this may not be possible. Finally, I was wondering if I could run the heatsink material up the ront of the shelf, past the glass, and into the water (this should give great heat dissipation) and have a SAFE and STABLE waterproof join between a flush glass-metal joint with possible use of epoxy and/or silicone caulking. Anything not specified in here I'm uncertain of how to do exactly. So! If anyone has any ideas, suggestions, or awareness that this is pure madness (or has a better way t oget those glitter lines i lust for) please let me know.

A Challenge: DIY gravity lamp

I have decided to power the lighting in my house with gravity alone starting next year. The idea started here: Greener Gadgets: Gravity LampI have some ideas about how to make it possible using some existing instructables and I though I would share this to get people thinking about new ways to use gravity as a power source. Think about it, gravity is clean, constant, eternal and EVERYWHERE. I think that this instructable has some of the essential components: Cordless Drill Crank Charge BatteriesIt gives a basic example of kinetic energy being converted into electricity, but for this application the kinetic energy will be supplied by gravity instead of the hand crank. The real fun with this project, I think, is the different ways that the kinetic energy of the weight can be harnessed. The screw used by the Gravity Lamp is just one method. A weight on a rope that is wrapped around a spool or crank is another option or even something based on the mechanism of a grandfather clock. One could even imagine a single massive weight that the whole family would hoist, with the help of pulleys, every evening to power their home lighting. Who knows.....It's time to start a gravity revolution.
