Dimmer switches provide adjustable control over lighting brightness in the home. These handy devices replace standard on/off switches to allow customizable light levels for any mood or activity. Dimmer switches work by reducing the electrical voltage flowing to a light fixture, enabling smooth transitions from full brightness down to a subtle glow.
There are several types of dimmer switches available. Standard dimmers use resistive load technology to control incandescent and halogen bulbs. Low-voltage dimmers adjust 12V halogen systems. ELV dimmers are made for electronic low voltage lighting. And LED dimmers are specifically calibrated for brightness control of energy-efficient LED bulbs. Each style matches the lighting technology in use.
Installing a dimmer switch begins by identifying the existing switch type and wires present in the junction box. The basic process involves disconnecting the old switch, capping the wires, connecting the dimmer lead wires, securing the dimmer in the box, then testing the installed dimmer for proper operation. Always exercise caution and follow local electrical codes when replacing switches. With a bit of care, homeowners can install dimmer switches to enjoy customizable lighting in any room.
