:: The MELW-ACEM-40K-SDT-BK brings the full emergency performance of the MELW Series in a black powder coat finish, the go-to choice for blending into darker facades, soffits, and modern architectural exteriors. Like every model in the series, it combines normal AC operation with automatic battery backup, dusk-to-dawn photocell control, and self-diagnostic testing so facilities stay code-compliant with almost no upkeep. Choose black when you want the fixture to visually recede into the building. Westgate offers the identical fixture in white and bronze for lighter or warmer facades.
