I’ve been using infrared bulbs on dimmers for years. Not only do they zap less humidity and run cooler then CHE’s. Using a little higher wattage then necessary and adjusting with a dimmer switch results in the bulbs lasting incredibly longer. Just for reference two of my boys from 2014 are well over 1700 plus grams. I use no UTH either. My two boys from 2016 are 1300 and 1500 grams. As a bonus, they’re are all mousers. And all appear to be extremely healthy. Peace
