It seems like a heart-sink is necessary; what's the SparkFun P/N for that?</p>

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 :)</p>

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.</p>

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.</p>
