Compact Fluorescents (CFL) are available in 5000K Full Spectrum to 6500K Full Spectrum Daylight Kelvin temperature range. Because they are in the above Kelvin range they can be used with film that is daylight balanced and of course most digital cameras. They are available in Medium (E26) and Mogul (E39) base lamps.

All values above are approximate incandescent equivalent and can vary from manufacture to manufacture. You should also check the lumen rating to find the right CFL. The higher the lumen rating, the greater the light output. CFL's deliver the same light output as incandescent or tungsten light bulbs but use about 75 percent less energy. 

CFL make great photography light bulbs to use in place of photoflood and quartz bulbs. They are much cooler and produce less heat and last longer than incandescent light bulbs. They will fit many photo lights that where made to use hot lights like photoflood, halogen, tungsten and quartz lamps.

Check your photo lights to see if the CFL lamps will work. You may need an adapter to fit CFL bulbs in your hot light fixture and some can be adapted to use the newer CFL bulbs. There are Mogul (E39) to Medium (E26) base adapters. There are Medium (E26) to Medium (E26) base extenders. If you know of an  base adapter not listed here please let us know. We are looking for more adapters that will allow the use of CFL bulbs in older hot photo lights. As always we will give you credit for your help and input.
