I'm planning a project to modify my floor lamp to use RGB LEDs. I'm using this lamp:http://www.ikea.com/us/en/catalog/products/80028552
For this project, I'm considering using the Power LED Shield to power one, preferably two of these RGB LED plates:http://www.dealextreme.com/p/30w-1500-lumen-rgb-led-emitter-metal-plate-39960
The green and blue channel require at least 32V, so it seems I need to find a 32V power supply. Unfortunately, I only need three channels, one for each color, so I'm not sure what to do with the four channel. Maybe I'll use it to power a white LED assembly.
Will I be able to power two of these RGB plates with one shield? If not, can two stacked shield share the same power supply?
For 32V, I think I can't use a laptop DC adapter as those supply only 24V. Any recommendations for those?
