This exterior fixture from MaxLite has an integrated photocell to help prevent operation during daylight hours. It comes with an 18 watt compact fluorescent GU24 lamp, but will accept all wattages of bulbs with a GU24 base. The fixture has a white powder coat finish, and is rust and corrosion resistant. The compact fluorescent lamp will deliver a similar amount of light as that which is produced by a 75 watt incandescent light bulb.
