Power CFL or T5 for 3ft vivarium
The vivarium is 3'x18"x2' and there'll be orchids in there,so I'm wondering which is a better option, power cfls or t5 lighting.
All the power cfls which I've come across didn't have integrated ballasts or were only in the region of 18-23w and of course t5s have a non integrated ballast which makes them more expensive.
However, I have come across a power cfl with an integrated ballast and pretty significant output today and was wondering whether one would be enough for a 3'x18"x2' vivarium. i.e 13,500 lumens
