I hope this is the right place to ask about this. It's for a magic prop and the color is very important to the prop.
I'm looking for yellow-green LED lights. Here's a picture of a LED scrolling bel...... I need. At first look they might look green but they are actually yellow-green. The difference will matter for my use because they have to match the color of another part of this prop. I just for the life of me can't find them (Just the bulbs). I've looked on line and found some information so I know they exist but I just can't find the bulbs themselves. I made some visits to Radio Shacks and they're no help either. Any help would be great.

Hi Jaxon, don't know if this will help. There is a company in the UK that sells them. I think they do overseas shipping. Heres the link if it helps http://www.maplin.co.uk/Search.aspx?crit......amp;SD=Y

There was a time when LED bulbs and related paraphernalia could be picked up at RadioShack, but now it's hit or miss. I'm constantly looking for red and green replacement bulbs for my LED flashlights and I stock up whenever I can find them.
Although I haven't yet ordered from the following site, I plan to because they seem to have everything that's made in LED technology. They do seem to have some fairly "strong" bulbs available in green and "amber", but I'm guessing it's going to be difficult to find bulbs in exactly the mixed coloring you might need without some kind of a diffuser to change the hue. http://www.theledlight.com/

I'm surprised Radio Shack didn't have them. You might check back with them and ask for the manager.
Lot's of times, the sales staff will contain a bunch of "slackers" who are too lazy to actually try to help people find something. It's easier for them to say "we don't have any!" Mark. |

Look for a company called "Digi-Key". I haven't ordered anything in years, but they used to have just about anything you could want in the electronics realm.
Things are more like they are today than they've ever been before...

Thanks for the links everyone but still no luck. They have all sorts of LED's on those site but not the color I need. It's getting frustrating because I know they exist and here's proof.
http://www.fireflymagic.com/fireflies_gs......odCGLQog This system has the exact light color I need. I don't want that system though. I just need the bulbs. The guy at Radio shack didn't seem to be one of those slackers. I've run into many of them. This guy really looked into it. Even went to the computer to search. He told me if I could find out the product number he could look for it and order some for me. But I can't even find that info. Thanks again. If anyone stumbles upon it please let me know. Ron Jaxon |

Have you contacted the firefly company to see if they will sell you the LEDs? I have found out that magic is novel enough that companies will work with you to get you what you need.
Also, I know that LEDs don't work this way, but have you tried dipping a white LED in some stained glass paint of the proper color?

I did think about putting a little spot of green on a yellow LED to see if it'll get the color I need but I was hoping to find some ready made that'll work.
Thanks for the suggestions. Ron Jaxon |

Ron, I went to my local radio shack and asked...no luck..BUT they said they can mail order them....ask your's if they would...no extra charge...just shipping.

Try "RS Components", in Germany I would also recommend the electronic suppliers liek "Conrad", "Reichelt", "Sintron".

Good stores specializing in electronic components (NOT Radio Shack!) often have a display board, all lit up and pretty, that show off their LED offerings. (A bit like the one on this site only bigger: http://www.anchorsupplies.com/leds.htm ) I would think that seeing the LED in person would be your best bet if you're really particular about the color. Unfortunately, these kinds of stores seem to be a dying breed. Maybe there's one near you?
Perhaps it might help in your search to know the approximate wavelength for the color you're looking for: http://ledmuseum.home.att.net/ledyelgn.htm Electronic catalogs spout specs and nanometers, but the latter is meaningless if you don't have a decoder ring. Finally, as already mentioned, if you strike out locating the exact color LED you seek, tinting a white LED might be an option. I did this once for a project years ago with tiny "grain of wheat" incandescent bulbs using a homemade mixture of epoxy, baby powder, and dye. I threw in the baby powder because I needed a more diffused effect. (Oddly enough, I was going for a "firefly" effect, just like the link you posted.) Good luck in your search! Ross Hironaka |

just saw this posting on ebay 4000 LOT SHARP YELLOW-GREEN LED 23mcd 120° 0603 SMD SMT They are selling them in spools for a pretty good price (I think) they say the color equivilent is ROHM green, not sure if that is what you need, but you can surely contact the seller and find out. Good luck Kay

Thanks everyone.
I'm sorry if this is a stupid question but I've never hear of a "Spool" of LED's. I see the image in the eBay ad but I can't tell. Is the spool a large number of these or is it more a rope that lights up? I just never heard of it before. Ron Jaxon |
ClintonMagus Inner circle Southwestern Southeast 3997 Posts |
A spool of electronic components of any sort is a bunch of them taped together in a long line amd rolled onto a spool. They are typically used by automated machinery for insertion into electronic circuit boards. A printed circuit board is inserted into the machine, and the machine detects the holes for the components, cuts and bends the leads and inserts the components into the board in their prescribed spots. Once the board is "full", it is sent through a solder bath and all the components are soldered at once.
There are several more steps to the process, but it is a very cool thing to watch. You should be careful with this spool, however, because I think I read that the LEDs are for "surface mounting", which means that the leads might be too short for normal use. Be sure to ask before bidding.

Thanks amosmc. After reading that I realized I have seen things like that being done on that show "How it's made". I love that show.
Thanks again. Ron Jaxon |

Ron,
you might also try FRY's.com. they are in Indianopolis and they have tons of parts in the store. Mark |

Electronic design is my full time job, at the bottom of this post are easy sources
to get leds in the U.S. (Sorry for the quick reply, but phone keeps ringing, so I did not get a chance to read all replies in detail. I missed if you need an array of leds, or just a single led. Your pic shows an array. But if you just need a single led you can Skip the next several lines. ======== array stuff ========= If you need arrays as your picture First you may not have to buy “bulbs”. LEDs come in “arrays” that could be mounted side by side. If mounted correctly you cannot see where one array stop and another starts. Yes, you could use separate LEDs to make an array, but this would be more wiring, or a PCB design (Printed circuit board). To make a small array you would use surface mounted leds which can be very small. ============ end array stuff ================= PICKING LED COLOR? The best way is to unfortunately order samples and look at them. Why? Most computer monitors are not “calibrated” to show accurately the real color. You will not know for sure until you get samples in your hands. When picking an led you also need to be aware off: 1. Brightness. 2. Angle of emission. (Viewing angle) 3. Current required. I don’t know your background, you may already know this, but don’t forget the current limiting resistor(s). Here’s some companies I have personally bought product from: I tried not to mention previous posters stores. . . P.S. If you must get exact color and cannot find it. If it is only a single led or two that you need you can go to one of the leds that have 2,3 or 4 leds in one case. (Looks like normal led with more wires coming out of bottom, but these are not cheap). You can get any exact color you want by adjusting brightness of single "die". The mixture can be any color you like. Leds come in two standard sizes. Arrays. very small, more difficult to handle (surface mount) ========================================================= Some suppliers of LEDs. Mouser http://www.mouser.com/ Jameco http://www.jameco.com Allied electronics: http://www.alliedelec.com/ Newark http://www.newark.com/ Alltronics (surplus stuff) http://www.alltronics.com/ I hope this helps in some fashion.
