Im looking for a good night time heat emitter for my beardie. Its getting a bit too cold at night and i want to make sure that Ash is warm enough. Ive seen some ceramic heat emitters ans some black light heat bulbs and read some mixed reviews so was wondering whats best. I have a 40 gallon set up. Ill post a pic. Ive taken the box at the bottom off lol pic was iust taken at first set up. What wattage and kind of bulb would be good for night time? Thanks
