I have bearded dragons that need light to keep temperatures between 100 and 110 degrees. This lamp heats up to 100 degrees without the need for a dimmer to adjust. I had an equivalent bulb that only reached 84 degrees and am ordering this bulb instead. It works much better and I like that it's smaller so it doesn't rest on the metal grille on top when my tank is a reptile. Time will tell if this lamp will last or not. I ordered 3 to have a spare in case it breaks out quickly.
