FLOWEX CORTEM
High Bay LED lighting fixtures
The FlowEx explosion-proof LED lighting fixtures combine the constant lighting power of 151 l / W real with extreme lightness, ease of installation and versatility for any type of certified environment. The FlowEx series consists of three lamp body sizes and represents the LED alternative for all those areas where it was customary to install low and medium power discharge lamps up to 400W.
The finned body, patented with Heat Destroyer technology, is made of high-quality die-cast aluminum and acts as an excellent heat sink for the circular crown-shaped LED plate. The central heat sink element allows the fresh outside air to disperse the heat by lapping the surfaces in an ascending movement of air that takes advantage of natural convection.
KEY FEATURES:
- Maximum overall efficiency of 151 l/W real and constant
- Lumen output from 4,784 lm to 27,961 lm.
- Wide range of voltages and powers.
- Optimally designed and certified according to the installation area.
