EVNL series LED lighting fixtures features high luminous efficiency (lm/w) "COB" (ChipOnBoard) LED lighting system, a Multichip LEDs formed of a LED matrix connected to each other and covered with a layer of diffused phosphorus.
On the other hand, EVNL-B series lighting fixtures and floodlights features a LED plate and the "Ex op is" protection which classifies the equipment as a device with certified optical safety. This is a point of pride for Cortem Group, which confirms itself as one of the few manufacturers in the world that actually certify the lighting equipment according to this method of protection.
The EVNL-B series can be supplied with 10°, 20° and 40° optics (60° and 80° optics are also available for the EVNL-60B series) fitted directly on the LED board, which modify the photometry allowing different concentrations of the light beam.
