Cortem SLED

Hazardous Area Floodlight – SLED
Cortem SLED hazardous area floodlights use LED technology combining compact design, lightweight, high performance in terms of reliability, safety, efficiency and energy saving.
SLED floodlights are characterised by LEDs with optics “square shaped beam” permitting a light distribution and a perfectly uniform lighting in every direction. This photometry ensures Cortem SLED floodlights are suitable for installation in the perimeter areas or wall in all those areas defined as dangerous for the presence of gas, explosive dust, such as hazardous areas Zone 1, 2, 21, 22.
The finned body of the SLED floodlight acts as a heat sink for the LED plate, allowing the installation of greater light output without incurring the deterioration of the LEDs.
Due to their high luminous output and to a white light with a colour rendering index greater than 70, SLED series hazardous area floodlights are able to replace the traditional rectangular floodlights that use discharge lamps, sodium vapour or metal halide, guaranteeing lighting quality and visual comfort.
