  • Heat emitters are possibly the best option as a direct heat source.
  • The benefits of the ceramic bulbs compared to traditional heat bulbs are that they do not emit light (only heat) therefore they produce more heat per watt than a traditional heat bulb that produces both light and heat.
  • Heat lamps emitting light are less than ideal for nocturnal animals, as the light will affect their sleep pattern.

  •  Heat emitters last a lot longer than traditional heat bulbs.
  • Dimmable clamp lamps include a built-in rheostat, which can lower the amount of heat produced by higher wattage bulbs when extra heat is not necessary. Please note that different manufacturers have different recommendations for dimmers and it is always best to follow manufacturer instructions.
  • The highest watt bulb (150W) has the most use flexibility when using a wire cage even without a base lacking a rheostat. A rheostat is helpful because it can control the amount of heat a bulb can produce.
  • The height of the lamp may be raised or lowered to increase or decrease the heat emitted in the cage.
  • Wire cages typically require more heat because the heat is not confined as compared to an aquarium with the same dimensions.


  • One should use caution when using the heat emitters with plastic tote type cages or any plastic accessory in the cage that the heat could damage.
  • The ceramic heat emitters must be used with a lamp base designed for ceramic emitters and rated for the appropriate wattage.
  • A traditional metal heat lamp holder is not sufficient as the wiring components are not adequately protected against the amount of heat produced by ceramic bulbs.
  • Please be very careful when getting your hedgehog out of its cage. The base shown does NOT have a protective shield. Surface burns will result from touching the hot emitter.

Figure 2 – ReptiCare Ceramic Heat Emitter

  • ReptiCare® Ceramic Heat Emitters are the perfect 24 hour heat source for all reptiles.
  • These porcelain heating devices screw into a standard porcelain incandescent socket, giving off intense “muscle-penetrating” infrared heat, while emitting no light.
  • The flat-faced design is more efficient and longer lasting than conical designs which build up excess heat internally, ultimately carbonizing the element.
  • Additional Information:
  • Last up to 5 years
  • Perfect for high humidity terrariums
  • UL/cUL classified when used in conjunction with Zoo Meds Wire Cage Clamp Lamp (LF-10).

FAQ from Zoo Med’s Website:

Figure 3 - Deluxe Porcelain Clamp Lamp

Figure 3 – Deluxe Porcelain Clamp Lamp

Q: What fixture should I use with this heat emitter?

A: We recommend using the Wire Cage Clamp Lamp (LF-10).

Q: Can I use a rheostat/thermostat with the Ceramic Heat Emitter?

A: Yes! A Thermostat or rheostat can be used to control the heat output of this heater.

Q: Is the Ceramic Heat Emitter coated with Teflon?

A: No. There is no coating on this heater.

Q: How can I ensure long life of my bulbs?

A: You can check your fixture by unplugging it and looking at the metal tab in the center – where the bulb screws in. This tab can be pulled slightly  forward to ensure that it makes a good contact with the bulb.

Zoo Meds most popular Clamp Lamp fixture is available in three sizes: 5 1/2″(14cm), 8 1/2″(22cm), or 10″(25cm) diameter domes. They are made of heavy gauge painted aluminum. All three models have a ceramic socket, and can be used with the Clamp Lamp Safety Cover to protect your bulbs, animals, and home.

To receive Full Warranty on Reptile Bulbs and Heat Emitters you must follow the guidelines below:

Figure 4 - Reptle Bulb

Figure 4 – Reptile Bulb

  • If bulbs are purchased in weather less than 60°F, allow the bulb to acclimate to room temperature for at least one hour before use.
  • If the bulb is dropped or dropped while in the fixture, the warranty is void.
  • For maximum life, it is very important to check your fixture/clamp lamp. To do this, unplug the fixture and remove the bulb from the fixture. There is a brass or silver tab (tongue) in the base of the fixture.
  • That tab should be at a 30-35° angle. If it is not, take a flathead screwdriver or butter knife and pull the tab down to a 30-35° angle. Do not pull too far or the tab may break.
  • It is very important that the tab comes into contact with the base of the bulb. If the tab is flat against the socket, it will not come into contact with the bulb and will create an electrical arc and your bulb will not last the 1000-1200 hours that it should.
  • Check your fixture every time you change the bulb. NOTE: Same tab rules apply for ceramic heat emitters and they should last at least one year.
