This is a 3-9W RGB LED, basically the same thing you’ve got on a little 5mm RGB LED, but with huge chunks of silicon that can handle large currents. Each of the red, green, and blue channels can handle continuous ~350-750mA current draw (with peaks of 2A) so you can drive this at an eye-blistering 9W. The light output is 150 lumens (150,000 millicandela) total at 3W, and ~300 lumens that at 9W.
