Looking for inexpensive source of RGB (Star) Luxeon LEDs.
I have an upcoming project that requires lighting a 10' x 10' matrix of 12" square LED driven lightboxes. The only requirement is the capability to display a broad range of color - hence the need for RGB LEDs. I'd like to go with more of a high-output Luxeon star mounted LED (1 or 3 watt) versus using several standard RGB dome LEDs. I figure that I can get away with using 1 Luxeon instead of 6-8 standard LEDs. My question is... does anyone have a reliable source for purchasing these LEDs inexpensively? I've seen several projects where people are getting 1W white units for around $3, but the Tri-color are selling online for around $14-$16 each. Any ideas?
