I hated the lights that came with my tanks. They are side-by-side so I bought two 20" wide hinged canopies and the above light. One less light to plug in and the canopies and light will work when I get my 20L.
When I need to replace them I'll probably get tubes better suited for plants. The cabomba and narrow-leaf anachris are growing so fast I have to cut them back once a week or the bottom plants are light-deprived.
I also bought some aquarium LED blue light strips that attach to the inside rim of the tanks. They are fully submersible. I run those at night.
