How much can you save with Legrand Lighting Controls?


Lighting is the second largest user of electricity in commercial buildings — and the third largest in homes. Legrand lighting ontrols put you in command of that energy consumption, enabling you to cut usage and save money.


Save with Dimmers

Dimmers turn power on and off 120 times per second, varying the percentage of the time power is actually flowing to lamps. The greater the off time, the lower the light intensity, and the greater the energy savings. Dimming enables lamps to run cooler, so they last much longer for additional savings.

90% 10% 2x
75% 20% 4x
50% 40% 20x
25% 60% Greater than 20x

 

 

Save with Sensors

People often forget to turn off lights, but Sensors always remember - so lights never stay on very long once a room's unoccupied.

Save with Timers

Timers are ideal for electrical loads that need to keep running for a predictable interval - with an automatic shut-off that doesn't require people to be present or remember.

Pool Pump, 1 hp 12 hrs instead of 24 hrs $35
