Surface & Suspended Solution
The %A-Line% is ideal for kitchens, because there are no external clips to hold the cover, making it easy to clean. It is also sealed to IP66, and versions are available that are suitable for ambient temperatures up to 50 °C.
Recessed Solution
If a recessed luminaire is needed, %Cleanline% is sealed to IP65 below the ceiling and is suitable for a variety of ceiling types including plasterboard. %Hi-Style% can be used in areas where a lower IP rating is acceptable.
Emergency Lighting
BS 5266-1 recommends an emergency lighting level of 15 lux on the work surfaces and on switches and cut-outs. A Risk Assessment is needed to determine where the increased illumination level is needed.
