It's a Home Depot light. Hampton Bay is the company and it's called "Under cabinet task and accent light kit". They are VERY thin, and they can be used in a "train" series. It's 18" long and only .88" wide. There is even less depth than the width. There is a cord ON/OFF switch and a semi clumsy dimmer pack/power supply. It has a mount if needed but I hang it out the back. The screws it came with mount perfectly to the top of the cage with no penetration.
Also check out "Light Your Reptiles" The Arcadia Moonlight. It is an option I will probably add later on.
