So much power and light from such a small package. This 5 pack of red 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 vibrant red light. Additionally, each LED requires a forward voltage of 2.0-2.8V 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.

Um.. I love you guys at Sparkfun, you have contributed so much to the community and you have the best customer service department ever.
But. The title says 3W, but right underneath that it says 2.0-2.8V at 750mA. Umm.. 2.8*.75 = 2.1Watt.
Perhaps not a big deal, but Not Cool guys.
Interesting catch. Thanks for sharing. We'll try to sort this out and change things to reflect what is correct. The supplier provided that datasheet, so we'll have to check with them for clarification on why the data isn't adding up.
Work great! I used 48 of these in my Internet Connect Fundraising Signboard with the Femtobuck LED Driver. I wired them in 2 parallel chains of 3 LEDs for each segment of the light. They are really bright -- you can see them in daylight easily. Biggest problem was mounting them. I tried the Theragrip Thermal Tape, but it didn't work well with curved surfaces. I ended up using this thermally conductive epoxy, but it would be great if Sparkfun could sell epoxy like this in smaller quantities.
These LEDs are insanely bright. They concentrate so much light into such a tiny area they are painful to look at. Awesome.
