I've been using "under cabinet led lights" for a while also... I just bought one of the led strips to try out, it's long enough that I can cut it and use it for multiple terrariums. You can bend it or cut it and use right angle connectors. It's almost flat and it's cheap... and you can get it in white or "RGB" which has lots of colors to choose from. Oh and lots of them have remotes to control the lights and some can even be controlled from your phone. I think it's going to work really well for me, thought I would share here since OP will probably be looking at lights.![]()
