How to Install A Dimmer Switch?

Standard wall switches provide simple on-off control of light fixtures. On the other hand, Dimmers allow you to alter the amount of power a fixture receives, changing the lighting intensity. A rheostat—a big variable resistor—was used in older dimmers. As the rheostat’s resistance grew, the voltage to the lamp was reduced, and the energy that…


Cat6 vs Cat5e: What’s The Difference?

Computer networking is a complex world. There are endless combinations of protocols, standards, and other variables to consider when building out your home or office network. And if you’re like most people, you probably have no idea what half of those things mean. Fortunately, it doesn’t have to be that way. To get the details…
