Ok so I'm currently doing something really small with HTG's G3 LED UFO right now, but true to my CFL roots, I'll be running one cfl in my cabinet for now. Just to supplement the red spectrum...
GE now makes "reveal" series CFL bulbs. These bulbs were previously only available in incandescent, and also I think some PAR halogen configurations, but NOT CFL. Now they are. I think these CFL bulbs are probably the best cfl for flowering due and I'll show you why...
The first image is pretty straightforward. On the left is the spectral output of a GE 2700K warm white CFL. These seem to be the choice for flowering up until now... The middle is a copy of the photosynthetic response curve. On the right is the spectral output of the Reveal CFL, as compared to an incandescent bulb... What you see is FAR more light in the red range.
GE sells these bulbs because they claim they produce a different lighting effect that flatters your posessions because of the extra red light... I bought a couple on sale and to be honest, in my living room I saw little difference between the Reveal bulb and the 2700K bulb. Be that as it may, I am confident the reveal bulb will produce better results in flower and wouldn't hesitate to recomend it.
The bulb itself comes in all the same wattages (up to 26watts) that you'd expect to see in a CFL line... Output is a little less lumens (although I hate even MENTIONING lumens after all I've read recently) at 1450 lumens... Also for those who care, I believe the Kelvin temperature is something strange like 2500K, I can't find the datasheet on GE's website where I saw it yesterday...
Anyway, the base of the bulb (see second pic) is a light blue and I'm not sure why but I noticed something cool: It's a good visual indication of how little blue light the bulb produces. When the bulb is on and fully warmed, if you look at the center of the blue base cap, it is difficult to tell it is blue at all. This is because it is being illuminated by hardly any blue light at that point of focus
The credit for all of this goes to CFL weasel on GC
