You DEFINITELY need at least a dimmer (approx. $10 at hardware stores), those types of UTH get extremely hot. When I was testing mine on a separate enclosure it got upwards of 113 degrees F! And you need to monitor the temperature under the substrate as well as on top of it. BPs burn so easily, better safe than sorry.
