LED Lighting fixture DKU B Budgetary series
LED lighting fixture DKU B is intended for illumination of roads (type B, C), streets, courtyards, parks, crosswalks, lanes, parking lots, checkpoints, guarded objects, etc.
Seoul Semiconductor LEDs are used as a light source. The luminaire body, developed by the specialists of our company, is made of aluminum alloy, and effectively removes heat from the LEDs. Thanks to this design, the DKU B LED luminaire has a service life of about 100,000 hours with no more than 30% loss of luminous flux.
