I'm looking for a hood that I can put on top of a 10x20 inch glass lid.
Hopefully, it would be bright enough to grow plants in a (deep) 20
gallon freshwater tank.


After a couple of weeks of looking, all I've been able to find so far
are 10W chunks of plastic at Engulf & Devour Pets, or when online, 500W
marine setups that put out enough photons to compete with collapsing
neutron stars.


Any ideas where I could find a happy medium between the two extremes?
Maybe something around 80 W and under $100?
