Clear for Life aquariums do not come with a light by default. They do come with a polycarbonate light plate(s) that sits on top of the access openings and is compatible with modern LED light strips.
If you’d like a light, we can special order one for you and include it with your shipment if you're planning on a non-planted tank or tank with no live coral. Otherwise, we recommend the lights from https://current-usa.com.
