The most reasonable site and soulution I have found for these lights.
“With the arrival of Cool Lights, those wanting affordable, cool studio lighting will not have to go to the great lengths that Richard did to research, design, find parts, custom make sheet metal boxes, etc. in their quest for a reasonable alternative to tungsten lighting! ”

Using two of our special (optimized for video and digital photography) 55 watt biax (PL 2G11) type bulbs, this fixture can put out an equivalent of almost 500 watts of flicker-free (and quiet) light for drawing only 110 watts. It really is the “cool” choice in studio lighting. Two of these units are very useful as part of an interview lighting kit or for a small studio.
The CL-255 comes with 2 High CRI (>87) 55 watt bulbs (available in choice of 3200K or 5600K),
price $179
