The E5 recessed direct, at only 2" wide with a 1-1/2" aperture, delivers an even concentration of light in a slender package. Various optics options are offered but for LED, the recommended optic is our WISP™ + HTLO™ lens combination: a delicately frosted opal acrylic captive lens with an insert of a highly transmissive (93%) linear patterned material that obfuscates any LED image.
