different spectrum 40w cfl

does anyone know if there are different colored (blue, red) 40w cfl bullbs? i'm trying to be veg and flower color specific, but can't find any bulbs. would they be called something else? help please!

The COMMON 42 WATT CFLs found at Lowes are Warm white, or 2700K for Flowering, they are the Red Spectrum. Mostly for BLOOMING or FLOWERING.
Kelvin is a measure of temperature, as in 6500K, 5100K or 2700K (this is the emitter temperature, not the actual temperature of the bulb itself), and it refers to the color of the bulb; 6500K being a blue light spectrum, and the 2700K being a red spectrum.
5100 is a blend of both. Plants like a predominately blue spectrum during their vegetative growth and like red spectrum light during flowering. Together the 6500K and 2700K provide a dual, or complete spectrum, suitable for all plants during all phases of growth.

You'll need a High kevin bulb for Vegging. a low kevin bulb for FLOWERING.

To the eye, you'll see a creamy colored bulb for warm white and a bright white colored bulb, called cool white, for VEGGing. It is almost a blueish white.

I've looked for bluer 42w cfls, could only find 2700k's. If you have the money, consider a t5-ho tube flourescent. I've noticed more lumens, with less heat, and different colored bulbs are available. They are more pricey than the cfl's, though...

yeah, i considered those, but i have my cfl w. reflector, and my grow is TINY, so that's all i need. just looking for a loophole to up my yield

do you have a credit card so you can order off the internet?
Lowes has some 65 watt OUTDOOR FIXTURES, that come with a good 65 watt CFL for VEGGING, but they need special wiring.
