I did a quick check over there but didnt come up with anything - you know how big threads can get on RC. Regardless, what I think is needed is a controlled A/B comparison with variables accounted for, something like what Sanjay does. Numbers that other reefers provide have to be taken with a very large grain of salt.

I am not skeptical about how well they work, but about T5 lamps having a definite numerical advantage over metal halide.
