I found out about them on the Icmag forums https://www.icmag.com/ic/showthread.php?t=112670
The ballast is a Fullham workhorse 8. It puts out 220 watts, which (in this configuration) will power 4 of the 55watt lamps shown.
The lamps and sockets combined are just under 23" long. These are perfect for a personal grow.
These lights are very bright! Turn them off when you are near the cabinet, or you WILL fuck your eyes up. I wired them through a light switch so i can turn them off easily while I'm tending the plantlets. I also installed 4x23watt cfl that dont run through the switch- so i can see what I'm doing when I turn the main lights off, and spectrum supplementation. The 55 watt pl-l's are 3000k, and the 23watt cfl's are 5000k.
I got these lights+ballast+sockets from 1000bulbs for just over $90 + shipping ($30 to Canada)



Any thoughts?
