The Arcadia Reptile Ceramic Heater Bulb produces and projects high quality deep Infra-Red’ heat far into an enclosure. 
Being Infra-Red, these lamps emit no visible light and as such are the perfect choice for many systems where heat is required throughout the day and night without disturbing essential circadian rhythms with unwanted light. 
The Ceramic Heater Bulb should be used with a pulse thermostat. 
Available in 50w, 100w and 150w.
