A cost-effective range of robust vandal resistant and energy efficient bulkhead luminaire is suitable for wall or ceiling mounting. An IP65 rating is achieved through a poured gasket seal which, along with a screwed down polycarbonate diffuser, rigidly constructed polycarbonate base and strong symmetric shape protects against abuse. It is ideal where durability and longevity is required, and suitable for interior use in youth centres, housing association buildings and sports areas, and external use in walkways, car parks and loading bays.
