ZEUS LITE is a high-performing commercial downlight with a recessed opal diffuser for low glare and IP54 protection. Three bezel sizes, 110, 190 and 230mm, cover 850 to 3,500 lm, with 3000, 4000 or 5700 K selectable. The universal halo surround lets one downlight fit several cut-out sizes, its oversized bezel hiding ragged plasterboard edges on refurbishment projects. Old holes, new light.
