Has anyone else looked into using Xenon bulb lighting? The bulbs are small like halogens but, don't get nearly as hot. You can actually touch one that is on without getting burned. If these bulbs work for planted aquaria, you wouldn't have the heat build-up issue. I'm just not sure what the Kelvin temp is. I'm trying out a strip of them on my 10-gallon tank.
