Best Dome Lamp Fixtures for Reptile Heat and UVB

Updated How we research

The dome fixture is easy to treat as an afterthought and it is the component most likely to fail in a way that matters. It holds the bulb over the animal, shapes the beam onto the basking site, and sits directly in the path of a great deal of heat. Fixtures vary in socket material, with ceramic sockets needed for higher wattages and ceramic emitters, along with reflector finish, cord specification, clamp strength and whether a guard is fitted. We weighed the stated wattage rating and socket material, reflector quality and beam shape, clamp grip on a rim or stand, hanging options for mesh tops, the presence of a safety guard, and behaviour with dimming thermostats. Smaller domes suit low-wattage bulbs over compact enclosures. Deep, wide domes suit high-wattage basking lamps. Ceramic-socket models suit anyone running heat emitters or higher wattages overnight.
