Sigma's weatherproof lampholders are used for outdoor security or aesthetic lighting applications in wet, damp or dry locations. These lampholders fit 1/2-in knockouts in weatherproof boxes and covers. Their rugged, die-cast construction prevents moisture penetration and is powder coated for corrosion resistance. The adjustable lamp head can be angled to illuminate a desired area and can be installed to activate with a switch or using a motion or dusk-to-dawn sensor (sold separately).
