I have been shoping around for a MVB. All that the stores carry is Exoterra Solar Glo or Zoo Med Powersun. I know most people recommend Trex or Megaray. Does anyone have experience with the Exoterra or Zoo Med Powersum. It will be for a uromastyx in a 40 gallon breeder. Also, can anyone recommend what wattage to get 100 or 160 watt? I would appreciate any help
