Arcadia offer a compact (75mm diameter) Ceramic Heater Bulb which emits heat without a light source in 50w, 100w and 150w. This makes them ideal for a night time heat source but they can be used for 24 hour heating and should always be controlled with a thermostat for correct climate control. We recommend controlling the heat ouput with a pulse thermostat.
This bulb will fit into any E27 bulb fitting that is rated for the correct wattage. Heater elements should be protected by a light / heater guard.
