High output technology produces a clean white light and creates a safe working environment, providing over 260 lux at 1 metre. At just 14mm deep for the surface mount version and only 3mm for the recessed unit, these lights can be fitted in a multitude of applications. The Megalux Enviro is suitable for installation in a variety of environments, including refrigerated vehicles. It is also rated waterproof to IP66. The electronics used within the PIR sensor/switch version have been designed to detect the movement of body heat to activate the sensor. Once the sensor has been triggered, the unit will switch on for 5 minutes before automatically switching off, preventing any unnecessary load, thereby extending battery life. If continuous movement is detected then the lights in the vehicle will remain on.
