I've used both bulbs (100 watt flood bulbs) and Spot basks much more under the t rex. It seems to be stronger. I had trouble getting the basking area warm enough with the powersun - to get to the ideal temperature it would have had to be too close so in the end the basking area was a little cooler than Spot likes. I think another person on the forum uses a Powersun along with an incandescent bulb and that seems to work, but then you're back to a two bulb setup.
