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 3.2-3.8V at 750mA.
Note: We like to joke around about super novas and all, but seriously, don't look directly into the LED.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

These are very bright. I used one set of 5 to light up my workbench. They are a little difficult to solder. I had to use flux and my iron at a high temp. Once I used the flux, they soldered well. I would appreciate a soldering tutorial if Sparkfun wanted to offer one.
These things work great.
They were easy to set up and produce lots of light. I will be buying more of these
Biased these at 375 mA. Working out great. These are on probably about 10 hours per day, a little over 1 year. No failures so far.
Exactly fits the LEDs used in outdoor LED lanterns from Altair that were on sale at Costco's a few years back. Half of them broke after 3 years, replacing the LEDs will hopefully give them another 3 years. They are working alright for now, cannot say anything about actual product life yet.
I bought these to replace a blown LED module in a cheap desk light. Working well so far and an improvement on the one it replaced.
Not as warm a white as I had expected though.
