Zoo Med brand 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 all bulbs within the dome, including the large sized 160W Powersun bulbs. Includes a switch along the 6' chord, so you can use it with a timer or by flipping the switch.
