Our take on the ProSun Cosmolux GSP 9K90 F71 100W #10990 Bi-Pin Tanning Lamps, 4-Pack

ProSun Cosmolux GSP 9K90 F71 lamps are 100W bi-pin tanning bulbs sold in a 4-pack for commercial beds and booths. The F71 length and bi-pin base fit standard 100W tanning canopies and beds that take that format. At $158.99 for four at Spray & Sun as of November 3, 2026, that is about $39.75 per lamp, and it is the only new price listed.

Questions and answers

Will these fit my tanning bed?
They fit beds that take 100W F71 lamps with bi-pin bases. Check your bed's manual or the old lamp label for F71 and bi-pin before ordering.
How often should tanning lamps be replaced?
Most salons replace lamps after roughly 500 to 1,000 hours of use, when output drops noticeably. Home users often replace a full set every one to two years.
Is this a good price for four lamps?
At $158.99 for four, it is about $39.75 per lamp. That is in line with other 100W F71 lamps, but only one store lists this pack new, so compare per-lamp prices before buying.
Can I mix these with my existing lamps?
You can, but mixing old and new lamps gives uneven tanning across the bed. Replacing all lamps at once keeps output consistent.
Are these for commercial use?
Yes, ProSun lists them for commercial use, so they suit salon beds as well as home units.
