(not exactly as shown) Used in most 2006+ SunMaster tanning beds. Super efficient, extremely cool running, state of the art. They are the most advanced ballasts available. Designed to push 1 to 4 lamps in the F71-F74 100W range. Can be used to power two 160W lamps, but is not within specification to do so, thus not warranted for such. (this is a more powerful way to push two 160W lamps than the WH8) Please note: This is NOT a retrofit for other tanning beds, and it wires up VERY DIFFERENTLY. If you are looking for a replacement ballast for a NON-SunMaster bed, and you are not a technician, don't order this ballast. Like all electronics, it is non-returnable for other than defect.
