Review on Reptile Halogen Spotlights Spectrum Reptiles by Jess Gunderson

Got this at 100 watts for my nile monitor's 40 gallon aquarium. The lamp is very weak and does not generate the heat that the electricity should generate. The warm-up temperature only reached 85 degrees. Typically a 100w bulb will heat up around 110-115 degrees in this tank. I don't know what to do with the onions now because they aren't hot enough for all the reptiles I have. The 50w bulbs that I bought from another brand get hotter than the 100w bulbs.
