LED Tubes are an established method of cost effective lighting and energy saving / conservation. Using the radar controlled LED Tube with its’ built in Microwave sensor, the potential savings are multiplied. The unit dims to only a 10% level when left on, rising to 100% whenever movement is detected, returning back to the 10% level after 60-90 seconds. This allows for a small amount of ambient light whilst areas are unoccupied or not in use. Offering massive savings in electricity alone. The LED Tube fits in existing battens with minimal wiring or if you currently have LED Tubes, then they are a direct replacement.
