Yes, they absolutely are.
I would argue that's THEE most popular PVC cage in the industry right now. I have several of them. A lot of people use Radiant Heat Panels with them (Pro-Products seems to be the go-to brand). I use 65 watt pro products panels in my AP T8's with excellent results.
Many people also like T10's because they're easier to clean due to a few more inches of vertical height.
