Re: [APD] GE "Daylight" CF screw-in bulbs?

I used many twisty tubes in their early days in regular aquarium hoods 
(when they would fit).

My experience was that their lifetime was pathetic when used in any 
position but base down, as in a normal table-lamp socket. YMMV.

In a hood, they blacken early and lose considerable brightness while 
still young. The ballasts often died in infancy, too. Maybe they are 
better now, but I suspect not.

The shape means an efficient reflector is nearly impossible to design 
and keep reasonably compact.
