A while ago I made an LED-lit candelabra inspired by a computer game I like: http://imgur.com/a/8TjPU - it is powered by a controller intended for RGB LED strips which typically seems to accept 12 V inputs for all three channels. I put three high-power LEDs in series and adapted the voltages to my needs by placing some high-power resistors in series as well. It works but the tubes aren't evenly lit. I can control it from my phone which has an IR emitter.
I want to do it again but using many low-power LEDs stacked on top of each other rather than single high-power LEDs shining from the bottom of the tubes. I will use convex/inverted cone LEDs to give a wide viewing angle. The problem is that the overwhelming majority of remote-controlled RGB LED controllers are for 12 V and 24 V LED strips where as my LEDs will accept something like 2.4 V and 3.2 V (x2). With 100 LEDs in series this will be around 2A per channel, I think.
Any suggestions? I'm hoping to escape doing the complicated circuit building stuff myself (has worked so far :P).
