Description: So much power and light from such a small package. This 5 pack of “Cool” 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 cool white light. Additionally, each LED requires a forward voltage of 3.2-3.8V at 750mA.
Note: We like to joke around about super novas and all, but seriously, don’t look directly into the LED.
Features:
- Forward Voltage: 3.2-3.8V
- Forward Current: 750mA
- Viewing angle: 125±5 Degrees
- Luminous Intensity: 160-240LM
- Temperature Color: 6000-7000K

Fair to Good Quality for the price
Used 3 of them so far, very bright, looks to be well made construction will have to wait to check for longevity. Good for Experimentation and such for the price. Would like to make a large light panel for above a workbench doing high detail work, to see if it would be economical to run compared to other light sources.
Do these need heatsinks?
You guys should carry more high-power LEDs. I really don’t enjoy risking it & buying stuff from Ebay. I would love to buy from you guys b/c I trust you and you have excellent shipping costs due to USPS options :)
Just received an email from Sparkfun–about a week too late. I bought 20 of these at twice the price. Aux/driving lights on my motorcycle using 10 degree lens. Stylemonkey–regarding lens, I use this: 1WS-LM10. Four leds in series with a .47 ohm, 1/4watt resistor.
Wavelength looks a little off. 6000nm is ultra-far infrared. I think perhaps you mean color temperature. Wavelength should be 400-700nm. Though, white is a blend of many wavelengths, so this still doesn’t work too well.
Is the example picture with one LED or all five?
Does anyone have any recommendations for lenses to use with these LEDs?
