You might want to grab your sunglasses, your sunscreen, and a bucket hat because this 3W RGB LED is so bright it's like taking a beach vacation ON THE SUN. Maybe that's an exaggeration, but these are incredibly bright.
This is a 3W RGB LED, basically the same thing you've got on a little 5mm breadboard version, but with huge chunks of silicon that can handle large currents. Each of the red, green, and blue dice can handle continuous ~350mA current draw (with peaks of 1000mA). The light output is 110 lumens (110,000 millicandela) total.
Each order comes with one 3W LED on an aluminum PCB/holder/heatsink. Please note that even though the PCB acts as a heatsink, 3W is a lot of power to dissipate as heat so you will need an additional heatsink or fan or other cooling mechanism!
