Any experience with the Arcadia DHP?

I recently picked up a 3 stack of Vision 222 enclosures, and I'm debating on what method to use for heating. I don't want to use Ceramic Heat Emitters as they get too darn hot on the surface and I don't feel they are safe in the dome cutouts of enclosures. I can't go with Radiant Heat Panels as Pro Products doesn't make one suitable for the space available, and the 28 watt from Reptile Basics won't be enough oomph.

So that leaves me with heat tape and bulbs. I was looking at the Arcadia Deep Heat Projector, and I can't find much info on them. Like how hot do the bulbs actually get? Will they be safer than Ceramic Heat Emitters? I may end up having to just order one and testing it, but would prefer to get some input from anyone who has first hand experience first.

The enclosures will likely be used as growout enclosures for some Boas, but may eventually be moved over to bull snakes.
