LA Aquarium Perfect - 13 Watts UV G23 Base Light Bulb 13W Perfect Working with Jebao Pond Sunsun Grech Aquarium Filter

This is a great quality UV clarifying bulb that works at top efficiency.

It works great for my aquarium canister. I hope it will last for another year.

The lamp failed after a couple of days in my 35 degree outdoor pond. I questioned the manufacturer and they stated it normally operates at 20-30 degrees Celsius. (68-86 F)

Arrived on time and a good price. Had trouble getting the electrical prongs fully seat into filter receptical. After about an hour it finally went in. Seems to be working ok.

Item works well but only last 6 months

I installed it and it automatically burnt out when the system powered on. Iv replaced this bulb a few times with high end bulbs and never had an issue. I wanted to try this cheaper bulb to save money and you get what you pay as many people say.

Does the job, but doesn't last long!!

Got this to replace the bulb on our "CNZ All-in One Pond Filter System with 13W UV Sterilizer 660 GPH Pump Fountain Kits." So far it has been working great. I was nervous when I first installed it, because I could not see the bulb light up, but apparently most such pumps have a safety switch that prevents the light from turning on unless it is installed in its sealed casing, as UV radiation can cause eye damage. I couldn't see anything coming from the CNZ's observation window either, which made me even more nervous. But the good news is that the bulb must be working because the water in our 100 gallon pond is crystal clear now.
