For sites that need much more heat spread over a wider area. High-output heater for lambing pens, chicken coops or horse stables. Not recommended for use in chick brooders. Due to their high heat output, Carbon Fiber Heaters should be hung higher than heat lamps. This allows heat to disperse over a large area and prevents hot spots. Available in 600 or 1200 watt configurations. (Bulbs and lamps are not interchangeable.) 600 watt heater has 12" diameter shade and 1200 watt heater has 16" diameter shade. Built-in “kill switch” turns the unit off if an unsafe angle occurs. So if it falls or is smashed, the heater is immediately disabled. Protects your buildings, livestock, poultry and pets. Carbon fiber bulbs have a very long life and are efficient—98% of watts become heat. When handling the heating element, we recommend wearing gloves or using a cloth to keep oils from the hands off of the element to maximize the life of the element. Also, do allow water to spray onto the heating element. Requires 110v electrical outlet. Warning: Risk of electrical shock—Connect only to a branch circuit protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot verify that the circuit is protected by a GFCI. Replacement Bulbs (sold separately) MUST be matched to the correct heater. Use 600W heater with 600W bulb. Use 1200W heater with 1200W bulb. The heater has 7.5 ft. of power cord. Some assembly is required.
