Hi! Dylan here. For the normal light, you turn it on and off, right? If you put a dimmer switch on your light it can reduce the amount of electricity you use, therefore helping the environment and your electrical bill. Did you know that residential lighting accounts for nearly 15% of the average American's home electricity costs? With dimmer switches, you can dial down the amount of wattage your lights are using helping your bill without losing the comfort of lights. This is Dylan, signing off.
