Spread LED light?

I'm having trouble using an LED to light up a vase. I have frosted a vase and was hoping to get a blue led to light it up from putting it in the bottom of the vase and give it a sort of blue glow, however, it is just not working. I can still see a big concentration of light where the LED is and towards the top of a small vase (maybe 8 inches?), there isn't much light. Is there a particular LED feature I should be looking at? Certain type? Certain voltage? etc? I was hoping the sunjar tutorial would shed some light (no pun intended) but it really didn't help much for my project. I was trying to get an effect similar to:http://www.westcoastmall.net/images/GS68.jpg or maybe http://www.vibride.com/images/photoalbum/38/ostrichfeather.jpgany ideas?

LED Christmas Lights?

I'm a freshman in college right now and I really want to spruce up my suite and room a little for Christmas. So Christmas lights would come to mind to display at my suite's door, but because of fire hazard rules/laws we can't have extension cords. I think I also read that we can't have Christmas lights period. So I started thinking I could make something out of LED lights to attach to our door so people walking by can see. I was thinking maybe an outline of a Christmas tree made of green LEDs would be cool or putting LEDs inside a wreath to light it up. Which would be the best way for me to power all of the LEDs? I've never worked with LEDs before, so this would be new to me but I really want to put something together. I basically want to chain a bunch of LEDs together, power them with batteries, and have the ability to turn them on at night and off in the morning. So, any ideas would help a lot. Maybe a point in direction.

DIY LED Growlights from LED Xmas bulb strings

I just got an Aerogarden for Xmas and it is a pretty neat little unit, but it has some annoying and expensive problems. The biggest one is that it uses CF bulbs that are on 16 hours a day, and they say that you need to replace the bulbs every 6 months, because the spectrum of the bulbs change as they age, making the plants grow less well. I did some research and found that the Weed industry has created a solution: LED arrays with a combination of red and blue LEDs (the color frequencies plants thrive on). These arrays are very long lived and use less than 1/2 the power of the CF bulbs in the Aerogarden. The problem is that even the cheap ones (200 LEDs) are $50, and you would need 2 for complete coverage in the Aerogarden. Then I had a brainstorm! LED Xmas Lights. They are already wired, ready to mount on a panel, and you can get Red and Blue strings of 100 on ebay for about $10 incl shipping. I don't know if they are the right Red and Blue, but it is an interesting experiment. Even if it does not work, you are set for Xmas lights for next year.

LED advice

So, i'm a pretty avid fan of our local roller derby team (HKRG BABY!), and i belong to a group of super fans who focus on doing a lot of weird crafting and costuming and other such insantiy for the bouts. so, i'm wanting to make some pretty fancy signs for next year's derby season that will  light up. i've got some plans to use some EL wire/tape and the accompanying equipment but i've also got some other sign plans that would probably be cheaper/easier to make using LEDs instead. so, basic premise is to have a sign that would be able to light up some cut out letters separately and sequentially. i know how to make the sign itself so that's not the issue, what i need is a method to cheaply and easily make the letters light up in sequence. so it's a 3 letter sequence (let's use D O A as an example) that progresses at the normal speed that you would imagine a large group of people chanting a 3 letter call sign to go. so the D would lights up for a second or two, one-two second pause, O lights up for a second or two, one or two second pause, then the A for a second or two, lather rinse repeat. i'm imagining that each group of LEDs for each letter would be wired in series, then each group would be wired to whatever circuit would be needed to make the lights cycle. i'm not sure exactly how many leds will be needed per letter, but maybe between 10-20 of them per segment? i'm going to have several of these types of signs (all 3 syllable chants) so i'd like it to be something that's easy to repeat and not terribly expensive (i'm a derby nut, but there is a line where cost kind of gets stupid)

Good LED Lights for Terrariums?

I'd like to buy cheaply or make a LED light for a terrarium cover, I'd like for it to be something good for the plants, but since the whole thing is supposed to be a display piece, the red/blue plant-lights aren't really going to cut it, I want it to be visually close to white light. (If that means some 'wasted' light in the green part of the spectrum, then so be it.)   Any suggestions? Some white LEDs seem to at least roughly cover the needed spectrum, if in the wrong proportions, but I'm not sure if that'll do it for me. I'd appreciate advice from anyone who's done a project like this.  Thanks!

LED Light Box Help!

Hey, I am very new to crafting things using LED's and stuff, but I want to get in to it, and have set myself a project as I need a lightbox for drawing/tracing for work. I want to make a A3 (29mm7 × 420 mm) sized box, with the aim to keep it as slim as possible. So I know that I need to use LED's because they are small and bright, I have been looking at white ones. I also know that I need some sort of frosted perspex to diffuse the light and keep the coverage of light even. That is important. A switch is necessary too of course! However I know nothing about what I need to connect the LED's together and how I am to power this. I would prefer to power this with power, but don't know how viable this is with LED's. I would just like a bit of advice of what I actually need then I will probably be able to figure the rest out!  Oh also if could keep the cost under £40 that would be perfect because if it was more, I might aswell just buy one from the shop! Cheers! Will

What type of LEDs are used for grow LED lights?

I've been googleing about the advantage of LED grow lights and how it saves energy and how they last longer. After looking to buy them I realized they were very expensive. However, I also found a few do-it-yourself guides which I thought were pretty neat and straight forward. The only thing I didn't see was if the LEDs they used were special or just any red/blue led lights can be used. Hope to get an answer and save a few bucks but most importantly save energy, Thanks in advance !!

Sense when garage door is open. Light/LED light turns on?

Hi there, I have an automatic garage. But sometimes i forget to close it and it stays open all night. Apart from someone being able to steal stuff, it would also allow an intruder into the house while we are asleep! So what I am looking to do is whenever the door is open, that a light inside the house turns on. My garage door is a panel lift door. My initial thought was to use alarm sensors. One on the wall and one on the door. If the sensors are not near each other, a light in the house should turn on. The serial circuit would look something like the following. GarageDoor > GarageDoorSensor > Less than an inch of air/space > WallFixedSensor > Wire > CentralLogicDeviceWithBattery > Wire > TinyLight/Led. The hardest bit would be what I have called the CentralLogicDeviceWithBattery. I would like to know what parts i would need and which part connects to which part. thank you

Best LED color to mimic incandescent lighting

Dan, Since you seem to be the wizard with LED's around here I figured I would pose this question to you.

So with that in mind what do you think would be the best selection of LED's for me, I was looking at the Luxeon Star LED's, but was wondering what color I should go with if I want that incandescent look, I was also thinking of creating a single rgb rig to control the color of the lighting for each lamp, your input will help me decide.

What is the best LED type for interior lighting?

 I am wanting to improve the light quality in my sailboat. I would like to build fixtures and controls myself and this looks like a good place for DIY ideas. I have a mix of light bulbs and none are serving all that well. All are 12VDC. All lighting will be powered from the 12V house batteries. The best light I have comes from halogen 20 watt bulbs but they generate too much heat and consume too much power. LED replacement bulbs I have tried so far are not so great for interior light quality and cost aprox $40 to $50 USD each and I have 10 fixtures with both red and white bulbs plus 5 reading lights. Total replacement cost could be aprox $1000 USD. Then the other problem is the light is a bright point and can be a bit blinding if your look in the direction of the fixture. I am thinking of wash lights for most lighting and keeping the reading lights for...  well, for reading. I do have an acceptable LED for the reading lights but always on the look out for a better one.  I have been on aircraft that used all LED interior lighting and it was the best LED lighting I have ever seen. The systems used a combination of white LED dome lights and RGB side wall wash lighting. The wash lights could be tuned to an impressive range of color including very pleasant white. So I know it is at least possible get really good light from LED's. Downside to this is it's expensive and designed for 28VDC from aircraft power. The controller was a dedicated cabin interior control module and computer. The other requirement for the boats interior lighting is to have red light for use while underway at night to help keep the night vision. Red LED's I have used for this are very harsh and poor quality for getting around in the cabin. I would like to try RGB LED's for a wash lighting system that will give either white or red. Preferably with both variable and dim-able so it can be tuned or programed as desired. The control modules I have found so far make a lot of claims for their multi-color capabilities but not about their steady on white light quality. Again I am interested in white and red lighting however if a large variation of colors is a side effect that can be turned on for fun thats fine but not needed. I would be happy to document my project and post it here if I find a good DIY solution. So far I have found a couple of RGB controls here and may try one but I would like to hear about the white light quality before I start buying parts. My homework for now will be to calculate an actual quantity of light needed and how many controls I would need/want.  Thanks for your ideas.

New LED lightbulbs shine light in all directions

GE is going to be releasing a new LED lightbulb early next year that shines light in all directions, like a normal bulb, instead of one direction like they do now. The bulb will use 9 watts and shine as much light as a 40-watt incandescent. It will also last for 17 years. The drawback is the cost, which will be $40-$50, but it does provide an efficient lighting option for those who don't like the light from CFLs. No word about the blades on the side, however.

architecture for grade 4-6, need lighting ideas

I volunteer on Saturdays in Watts/LA for a program with kids from grades 4-6. The program involves 6-8 week "classes" taught by volunteers, and I'm an assistant for a new class on architecture. We're building a structure, and I want to include both lighting and sound. For lighting, I sincerely apologize, I have no experience and not much time, can someone recommend a simple way to let the kids build some different LED effects, ideally AC powered, that they could incorporate into the scaffolding we built last week in first class (the structure will be about 6x6feet.) The second question, I think sound is essential to architecture, I happen to have some sanyo MP3 players, I was thinking of buying small MP3 speakers for each, and then letting kids experiment with what a wash of different sounds and music would sound like within the structure.Amazon MP3 speakers start at 20$. Any other options? I think it would be great to have strpped down speakers so that kids can build the speaker housing to incorporate into the architecture.  I can find + and - on a battery. Thats about the level of my competence.
