All non exempt wall mounted, commercial light fixtures are required to conform to current standards by January 1st 2020. Most nonconforming fixtures consist of unshielded lights containing bulbs in excess of 260 lumens (20 watts) or partially shielded fixtures in excess of 1,000 lumens (60 watts). Existing fixtures may be shielded or replaced with new fixtures that are full cutoff, recessed bulbs with no light shining above the horizontal plane. Neighborhood Services Staff will be happy to meet with you, to review your site and assist in making recommendations to accomplish the task.
