Zilla Incandescent 20" Dual Bulb Reptile FixtureTwo bulbs for twice the reptile habitat convenience. Thanks to this compact two-bulb housing, incandescent light and heat can fit in tight spaces. A low profile 4" high hood includes twin ceramic light sockets...perfect for daytime and nighttime bulbs. Both operate independently on separate cords with in-line rocker switches. An ideal match for day/night programming with an R-Zilla Power Controller (sold separately). Both fixtures are rated up to 150 watts and are CUL listed. For larger terrariums, place two of these 20" fixtures end to end. Please note that bulbs are sold separately.
