LED - 3W Aluminum PCB (5 Pack, Warm White)

COM-13104 RoHS

Description: So much power and light from such a small package. This 5 pack of “Warm” white 3 Watt aluminum backed PCBs is sure to shed a lot of light on any project you add it to. These LEDs act as any other LED except these little guys require much more power while delivering a light as intense of a thousand suns going super nova (this is an exaggeration but you know what we mean)!

Each LED in the pack sits upon an aluminum backed PCB to help with heat dissipation and emits a warm white light. Additionally, each LED requires a forward voltage of 3.4-3.6V at 700mA.

Note: We like to joke around about super novas and all, but seriously, don’t look directly into the LED.

Features:

Forward Voltage: 3.4-3.6V
Forward Current: 700mA
Viewing angle: 140-150 Degrees
Luminous Intensity: 200-220LM

I found Red, White and Blue. I am the only one missing Green? My plans involve RGB.

  Who needs green light? ;) Plants reflect most of the green light. They utilise mostly red and blue..
  
  Here’s a little image showing what wavelengths photosynthesis occurs on http://www.sd84.k12.id.us/shs/departments/science/yost/Biology/5%20-%20Energy%20&%20Metabolism/chlorophyll_absorption_graph.jpg
  
  P.S I like the direction SF is going, starting to sell peristaltic pumps, R/B LED’s, Constant current supplies, Atlas Scientific probes (K0.1 plz), etc.

    Red, Green and Blue are primary colors, which means you can create any color by blending different amounts of these three.
    
    So, in answer to your question, your plants may not need the green light, but anyone (like me) wanting to create a light with any color needs green along with red and blue.

  Sorry, no green :-(

    Thank you for your answer! Are they not manufactured in green, or did you just decide not to stock them? The number of possible applications of these leds increases significantly if there were three primary colors. So you would probably sell more of red and blue if you had green as well.

Could these work as bicycle headlights? All 5 at once in a little aluminum housing?

Can you run a 12V power supply with these?
- mxgxw / last week / 1
  
  If the forward voltage must be between 3.4-3.6V you can put them safely 4 of them on series, they are going to glow a little bit less but them are not going to require additional wiring. Just be sure that the 12V voltage source can provide at least 2.8A.

    The power supply does not need to provide 2.8A. It only needs to provide at most 700mA, actually a lot less since you won’t be running them at the full current.

      You are right, my wrong. In you put 4 them in parallel you are going to need at least 3.5v@2.8A, in series 12V@700mA would be enough as you said. Sadly I don’t see a datasheet, may be he can put 3 of them in series and over-drive them a little bit (even reducing their lifetime if the he doesn’t care).

This looks like a great product. What is the rated CRI, color temperature, lumen maintenance vs. time, recommended thermal resistance of the heatsink, and maximum junction temperature for this LED. Can you provide the datasheet for these?

  I think this might be it: http://www.vollong.com/UploadFiles/2011/13/2011131951237252.pdf At least the picture matches and the specs can be found in the mddle of the page. A CRI of 60 (for WW) doesn’t seem too spectacular these days.

I used to buy 1 watt LEDs in this form with a built in driver from another source. It was a simple and cheap way to create LED lights. I would like to suggest stocking something like the LED strips that another vendor carries http://www.goldmine-elec-products.com/prodinfo.asp?number=G20003 These are available in a variety of voltages. The driver is built in. You just add the correct DC voltage and you are good to go. I wish these things had proper holes for mounting to projects however.

Supernova? I think not :-) : https://what-if.xkcd.com/73/
Which of the following would be brighter, in terms of the amount of energy delivered to your retina:
* A supernova, seen from as far away as the Sun is from the Earth, or
* The detonation of a hydrogen bomb pressed against your eyeball?
Applying the physicist rule of thumb suggests that the supernova is brighter. And indeed, it is … by nine orders of magnitude.
Need I say more?
Oh, and thanks for the shiny quarter.
