250watt Ceramic Heat Emitter. Infrared heating without light. Allows proper day/night cycles for animals. Must be used with a thermostat.
Many reptiles require a heated environment but normal incandescents that are used as a heat source emit white light. This can interfere with the reptiles biorhythmic cycle and cause sickness and disease.
An alternative to using a light emitting heat source is to use the Oz White ceramic heater. This emits heat without the light.
These bulbs are Edison Screw type bulbs.
