I'm currently planning a terrarium build converting what was formerly a home for a pet to a highland carnivorous plant terrarium. The terrarium is a cube with 18" sides, and I'm not sure what the best lighting solution is. I've been looking primarily at LEDs, because they're generally cooler than compact fluorescents and fluorescent tubes seem to be too long for the tank. The best solutions I've found seem to be either corn lights or strip lights. However, strip lights seem like they would be very inefficient at lighting the sides of the tank without it being prohibitively expensive, and corn lights seem like they would have trouble because they would lose much of their light because it would be necessary to put it sideways to get the most out of it. Alternatively, they could be placed in a corner with reflective material, but that would both make it hard to get plants close enough and make overheating likely. Are there other solutions I'm missing? Are either of those I suggested good?
