The HSL11 has been engineered to utilize our NEW interchangable LED module while remaining compatible to MR11 halogen lamps. Our Storm Drain™ lens drainage system prevents water from collecting on the lens to reduce cleaning and stop hard-water deposits. Our exclusive AMS™ mounting system offers an extensive choice of mounting options, making this elegant accent light ideal for illuminating mid-sized trees and to cast subdued light onto low shrubbery.
