Use a reptile hood or clamp lamp fixture only. Make sure hood/clamp lamp has a ceramic fixture base for halogen lamp to screw into (no plastic fixtures). Only operate lamp 8-12 hours per day giving your animals an appropriate "photoperiod" (i.e: day/night cycle). Do not allow combustible materials to come in contact with the lamp (i.e: curtains, clothes, etc.). For reptile use only. If outer glass breaks, do not touch any part of the bulb even if the bulb continues to light. Immediately turn power off and let bulb cool.
