Zoo Med brand Mini Deep Dome ceramic based clamp light rated to handle up to 250 Watts of heat. It can be used with the included clamp, set directly on the screen top of a cage, or suspended with the Zoo Med lamp stand (works great for suspending it over low enclosures). This fixture is set deep to keep the entire bulb within the dome when using standard sized incandescents or the 100W Powersun bulbs. Includes a switch along the 6' chord, so you can use it with a timer or by flipping the switch.
