Do you remember the brand?

It's been a few years.

I used both ESU 7.0, and Zoomed's 10.0 compact fluorescents. When I first fired them up,the uv output was very high(more than direct sun) for about 2 weeks, then it would really go down. The uv was so high that a bunch of my dragons wouldn't even sit under them.

Now I just use tubes(zoomed 10.0, and exo terra 10.0). I have heard of people having problems with the exo terra bulbs too, but I haven't had any issues. Been using them for years.
