I love this bulb. It provides great heat while suppling the needed UVB & UVA.

When the bulb arrived I wondered if it was going to work because it sounded like a loose fillament. But when I turned it on, it worked fine. But in a couple weeks it seemed to dim. Then in approx, 5 weeks it wouldn't turn on without tapping the bulb. When we called to see if we could get a replacement it had been over the 30 days so we will try to get it replaced by PowerSun's warranty.
