Optical - a) Asymmetric pattern - billboards, open field, portable emergency and similar lighting situations b) Symmetric - tunnels, gas stations, parking lots and similar applications.
Power - Switching mode and multiple channel constant current design to drive individual LED series connected to the circuit to ensure constant current loading. The Power factor (PF) 0.98 @ 85 watt full load. Over-heat and over-voltage protection designed with self thermal compensation ensures long LED life and optical performance.
