The Lykos 4ft integrated LED batten light has been designed as a direct replacement for single T5 and T8 linear outdoor fluorescent luminaires. Consuming only 20w to provide 2000 lumens, this single LED non-corrosive fitting is an ultra-energy-efficient choice for industrial environments such as garages, public car parks, workshops and food preparation areas which require tough, weatherproof fittings.The integrated microwave and dusk-til-dawn sensor automates the lighting function of the fitting when the presence of motion is detected. With sufficient ambient light, the batten will not switch on even when motion is detected. When there is insufficient ambient light the fitting will switch on when motion is detected - after the hold time has elapsed the light will switch off if no more motion has been detected. The sensor has easy access to adjust daylight threshold settings, hold time (up to 30 minutes) and sensitivity of detection. The sensor can be overridden by switching the power t
