Sterilight S810RL, S8Q, S8Q/2, S8Q-Gold, S8Q-Gold/2, S8Q-PA, S8Q-PA/2, S8VQ-PA, SSM-37, SSM-37/2, OEM Quality Premium Compatible Replacement Lamp Bulb, .Guaranteed for One Year

I have a Sterilight UV system for part of my water filtration at my camp. I replace the bulb every year but the OEM bulbs are pretty pricey. These are about half price so I bought 2 so I had one for next year as well. They came quickly and are packaged in a separate round tube with a bunch of strofoam stuffing at each end. the two tube I ordered where loose in a larger box when delivered but have to admit the cardboard tubes the bulbs are in are pretty think and padded so there was no risk of breaking the bulb. Will buy again in a couple of years when needing more.

I have purchased and installed these bulbs in my well water treatment system for years. Purchasing two for less than the price of one from other sellers doesn't get much better.

Packaging was simple, could have been better for fragile light bulbs. But none of the bulbs were physically broken. I got them plugged in to the uv system and they all failed to ignite. Out of the 3 that I ordered. Not a single one was functional

Package was to big for glass tubes. They were easily shifting back and forth inside shipping box. They did not break.

Good fit for my water plant!
