Description: Do not look into the light. You know you want to, but boy will you be sorry. 1W per channel, RGB High Power LEDs in one aluminum backed package. These LEDs will blow you away. Light them up then put a coffee cup over the LED to keep your eyes from seeing dots in the periphery. With all three LEDs at 350mA per channel (3W total output), you will need additional heat sinking.

Features:

  • Viewing angle: 140-150degrees
  • Red: (620-630nm) / 30-40LM
  • Green: (520-525nm) / 40-50LM
  • Blue: (455-465nm) / 10-15LM

Forward Voltage:

  • Red: 2.2-2.6V
  • Green: 3.2-3.8V
  • Blue: 3.2-3.8V

  • Is this LED 350mA per channel or combined total of 350mA (i.e. 166.67mA per channel)? Hard to tell from the data sheet.

    • It’s per-channel. Keep the different Vfs and your power dissipation in mind if you actually drive them at 350mA (for which you should be able to find a multitude of drivers - 350mA is pretty common).

  • The LED I received doesn’t look like the photos or the datasheet. It has 2 R’s, a plus, and minus. Any help?

    • Basically, the printed letter “R” is next to the Green pair, then the Blue pair is in the middle, and the side that has the printed “+” and “-” are the Red pair.

      Obviously the + side (anode) goes to +, and the - (cathode) goes to your - side.

      So one side:

      (“R”) G B R (“-”) these are all the cathode pins for each color Green Blue Red

      Other side:

      (“R”) G B R (“+”) these are all the anode pins for each color Green Blue Red.

      These LED’s are awesome, but some of the ones I have got lately have had bad solder joints on the LED itself to the little tiny heat sink / board they come mounted on, so have had to re solder a few.

      Hope this was of help!

    • It looks like there might be a letter beside the + and - but it’s hidden by the LED’s. I’m also assuming there is a + and - beside the R’s but they are also hidden by the LED.

  • Just wondering if anyone has found this LED sold anywhere else. 15 dollars is a little steep. Im looking at about 100 leds.

    • Are you looking specifically for this LED? Or any power RGB LED? And do you just need the LED, or pre-mounted on a board (and if so - star board? hex board? round board?).

      If you need something similar to this one, then perhaps try this: http://www.digikey.com/product-detail/en/AAD1-9090BRGC-01%2F3-S/754-1331-5-ND/1887685

      It has the same type of power requirements (basically a 350mA current, but the current/voltage relationship is similar) and roughly the same claimed output. It is, however, domed rather than flat. You can de-dome it, but that’s a risky undertaking. At 100 quantity, it’ll set you back a good $756.

      The world’s ‘auction houses’ will also have plenty of (less verifiable) options, of course.

      • I have looked on several sites and nobody sells this led. I need a flat faced led, not a domed one. The domed ones are easy to find.

        • Yeah, if de-doming isn’t an option, finding something pre-mounted to a star board is proving difficult. There’s a few I found, but I wouldn’t say they’re all that price-competitive (led-tec in germany, flytech in italy, freaklabs - cheap, but on holidays?). You could try contacting young-sun directly, or roll your own using standard hex boards and whatever choice of mating flat high power RGB LED and a lot of soldering.

          Any particular reason you need the flat lens (as opposed to other solutions in e.g. the housing)?

          • The LEDs will be used in a car in replacement for the standard LEDs.

            We have tried contacting young-sun, but no luck.

            • Gotcha - so is the requirement for a flat lens a physical constraint? Otherwise I’m not sure why domed packages wouldn’t work / couldn’t be made to work.

              Unless SFE is planning to order a bunch more ($11.96 at 100+ units), your best bet might be freaklabs - the main page actually says they should have been back from holidays since Aug/31. They have no stock indication, though :)

              • I have talked to the guy at freak labs and he said he would be back from vacation on the 6th. He didn’t seem interested in selling 100 to me. Might just cough up $460 and buy all of the stock here.

                • He didn’t seem interested in selling 100 to me. Huhhh… weird. You’d think “easy money!” would be appealing (I’m assuming he gets them cheaper from OptoSupply himself).

                  Have you tried contacting SFE to see if they’re looking at restocking once these last 34 are gone?

                  • No I haven’t. That would probably be a good thing to know.

                    • Old comment thread is old, but there’s 97 in stock now.. so they certainly did re-stock. If you’ve found an alternative, that might also be interesting to include here :)

  • Does this LED have a domed lens on it. The Datasheet does not specify and without a side view picture it is hard to tell if the surface of the chip is flat or has a clear dome.

    • In case you’re still looking for an answer to your questions… the LED is flat on top, with no dome. It emits light uniformly over almost a full hemisphere.
      And while I haven’t driven this LED with the BlinkM MaxM, the MaxM would have no trouble. The MOSFETs on the MaxM are rated for 1A/channel, and this LED is rated for 350 mA/channel. So you could drive three of these RGB LEDs at nearly full power using one MaxM.

  • Anybody out there in tinker-land have any experience with driving one of these babies with the master board of a BlinkM MaxM? It seems like it would have more than enough current handling with a proper choice of power supply and current limiting resistors. Any insights?

  • These are killer RGB LEDs. The three LED cores are very close to one another, so the color mixing is great, with no weird color ghosting around shadows. It is definitely bright enough for indirect lighting projects.<br />
    <br />
    Also, the breakout board is aluminum and is really effective at dissipating heat. With a little thermal paste and a good mounting location, they don’t even get warm.

  • The brightness of these is AWESOME. Who doesn’t love LEDs?<br />

    Any tips on soldering these guys? I want to get some wires going to them but I’m not sure the easiest way to do this. The tutorials on surface mounts doesn’t really help because if you were to try to wick away the solder the wires would move.

    • Seriously guys… I am having a hell of a time trying to get the pads to wet with the solder. I have a 40W iron and it’s a no-go

  • With the price set at $14.95 you really can’t help but be a little skeptical… but if you are looking for a high power RGB LED this product does the job right.
    I used this LED as a replacement for the incandescent light bulb in a office light. One of the cone style lights with the inside coated white. I am using and arduino for control, the built in 5v works great with these.
    No issues to speak of, doesn’t even run hot thanks to the metal fixture.

  • I made a simple driver to use this with the Arduino and a +5V source (in my case from the PSU):

    Also you will find some SVG files I made for this tiny thing.
    Cheers

  • Pads are not as image indeed, really small and close together a b*tch to solder.
    really bright tho and good white mixing

  • I’m looking for a link to information on driver circuits for these triple output models. Any ideas?

  • How hot do these get?

  • And the link’s broken…

  • As makerman asked, where is the Spec Sheet? With the differences in the image here and the product delivered, it would be nice to know I had the right info. Besides, the big sticker on the mailing envelope said “RTFM”. OK, no problem, wher is the “M”??

  • Where is the datasheet for this?

  • Yikes! I really was not expecting the immense brightness of this thing! Get enough of these, and you could make a solid state lamp.

  • Hey! I just got one of these in the mail - and the solder pads on the heat sink are completely different… They are microscopic now! SparkFun should update the photo; or go back to using this style heat sink.
    This little guy is bright! I should have paid more attention to the warnings. I have major spots in front of my eyes.

  • This LED is really, really, really bright. It will be tempting to look at it. I did, and it didn’t blind me, but it was a good thrill.

    • Love it.

    • So I’m confused about this whole “painfully bright” thing. I’ve seen many comments about how these (and other) high-power LEDs are painful to look at, and that folks were afraid to feed them full power, etc.
      From what I can tell by doing the math, these LEDs aren’t any more powerful than a nightlight! I have no problem staring at one of those, so what am I missing?
      Is this because the light is emitted in a tighter beam, or because none of the energy is wasted in wavelengths that the human eye isn’t good at seeing? Or is it just really bright for an LED…
      Any thoughts on this?

      • the idea is that the light is radiating from a very small area, so it is concentrated, they are also about 3 times as efficietn as incadescent lights.

      • First, while “bright” is a descriptive term, it has no specific technical meaning.
        My experience is that when most people refer to “brightness” they are talking about either intensity or sterance. For these, they are talking about luminous intensity == luminous flux emitted within a specific solid angle (lumens/steradian). Intensity for these devices is typically higher than for incandescent sources that emit more total flux.
        On the other hand, sterance would be luminous intensity/unit area. Commonly discussed as the “brightness” of an entire surface. Unless you place the light source behind some diffusing material (aka. the coffee cup), the apparent size of the light source is very small. (point source)
        If you want to see more information on LED’s and eye safety, you could visit the Avago web sites. They used to be the HP Optoelectronic Division and they have a number of well written application notes on the subject.
