Re: [APD] 6 gallon nanocube


Twisty (spiral) CFs are far less efficient than straight or "U" tubes, 
IME. Restrike is only part of the problem, as the shape makes efficient 
reflectors nearly impossible. The strong restrike also seems to cause 
them to darken quickly in a hood. [Could be self destruction of the 
phosphors, IDK?]

The AH retrofit systems need to have a 1.6 (or more) multiplier applied 
to the traditional 2 W/G rule, because they use straight skinny lamps 
and efficient reflectors. If the JBJ setup is similar, the 18W could be 
like 29W of ordinary fluorescent light, and probably more than adequate. 
[I have no direct nanocube experience, so free advice is worth every 
penny. :-)]

I would never compare straight tubes to spiral tubes over an aquarium. I 
have used lots of both, and the differences are quite dramatic.
