CFL better than fluorescent?

Again, far different from:
The phosphours, and therefore spectra are the same across all tubes.


Do you not know what "all tubes" means? Or perhaps it's "spectra" you
don't understand?


I stand by my statement but perhaps it needs further explanation. If a tube
uses a SPX65 phosphour (it'll say on the tube) then it doesn't matter if
it's a T12, T8 or T5. That is there are no phosphours unique to CFL. While
it's true there are some phosphors that only exist in T12 size this is
jsut marketing and the ourput spectra of an SPX41 will be the same in
T12 or t5/biax tube.

Or put another way tube makers have a bunfhc of different phosphorus
they use to get different color light. They use these on all tubes
without regard for the tube shape of size - T12, T8, T5 (CFL) alike.

Although that's not strictly true, T12 still reigns supreme in terms
of the more esoteric ones. Only the most usefull are made into T5,
which works out ok for our purposes.
