I use them on my 4x2 panther chameleons and they have been great. I would recommend this bulb to any reptile owner trying to get an adjustable heat source for seasonal changes or just because you're tired of guessing what wattage to buy. Not to mention you can set your temperature so it can be used on very low settings and potentially last longer. Overall a great bulb. I am writing this review a year after purchase and the lightbulb has just died.
