How many "clouds" and how bright do these need to be? I've used 3w rgb(1w ea color) leds before and they are pretty awesome(small, wide angle, smooth dispersion, bright) but you need 3 350ma constant current supplys and corresponding switching device per led, or if you use individual 1w leds you can string them in series and save on the supply count and use a higher voltage
I’m planning on three “clouds” with two lighting elements a piece. They don’t need to be terribly bright. They will not be relied upon for ambient lighting. It’s just accent lighting.
I usually just search ebay for 1w led or 3w rgb led and see what has lowest price and free shipping dealextreme.com also I found has rgb leds for comparable price with free shipping
