Created by Morlite from Philips, Defiant II is a family of die-cast aluminum abuse-resistant indoor and outdoor wall- or ceiling-mounted lighting fixtures, suited for a range of uses such as sports arenas, shopping malls, apartment complexes, transportation terminals, and incarceration facilities. The luminaires have a flat plate for surface mounting and a deep back box for recessed mounting. They have profiles of less than 4" to protect against damage. A keyed outer locking ring secures a convex lens, sealing it to a metal back plate. The light source is a choice of low-energy triple- or quad-tube compact fluorescent or low-wattage MH or HPS lamps with Class P sound-rated electronic ballasts standard. philips.com
