It's probably nothing but was just curious and wanted to make sure. Is it normal for the uvb light to blink on and off a couple of times before turning on completely??
That explains it then...that's exactly what I have, an ESU. It has a brand new bulb that I just got about a week ago. Thanks so much, DavidY, You're the best!
The tube fluorescents I've used have always blinked when first turned on. I've always used Reptisuns. Don't know what kind of fixture - several different ones over time.
Actually, regular fluorescent tubes like people use often blink, too. I think they do it more when they're about to burn out.
