Those are standard T12 fluorescent bulbs, I think. They rarely have effective reflectors, if they have any at all. So, the 50 watts you do have is less effective than AH Supply lighting kits, which have very good reflectors. Effectively I suspect you have less than one watt per gallon.

no question they are nowhere near the AH supply kit as far as effectiveness goes.

Yup- seems general consensus is that you're going to have to upgrade your lighting to keep just about anything alive.
