Changing to low energy light bulbs can reduce energy consumption and simple timers can reduce some of this overhead. But such lighting is still often left on when rooms are empty, as illustrated by the night-time city skyline.

Two products that include Constant Daylight functions are the Dura-Tech DLC100 and DLC200 Lighting Control Modules from DKSH. These modules work in conjunction with multiple DLS1000 sensors to constantly monitor for absence and light levels, adjusting lighting for a comfortable and energy efficient working environment.
