Wiring Connections for a Single Light Switch Controlling a Light Fixture At a single light switch often there is an incoming "hot" to the switch and an outgoing "hot" from the switch to the light or other switched device. The third wire could be a ground, or the box in your photo coul...
[2] So it's good for your pocket and kind to the Earth as well. There are two quite different kinds: CFLs (compact fluorescent lamps) and LED (light-emitting-diode) lamps. What's the difference between them, how do they work, and which is best? Let's take a closer look!
In the image above with the splice in the cable, the module will measure the current flowing to all devices plugged into the power strip. Figure 4: For module measurement using a CT, the load wire (black in the US), is passed through the opening of the CT either via a split core ...
Like any other trend, cove lighting design is constantly evolving to keep up with modern times. If you have fluorescent or incandescent lighting fixtures (or no lighting at all), this is the time to learn about beautiful LED cove lighting. Not only are LED strips extremely flexible, but they...
The only time I've had LED lights glow without the switch turned on was when used with an electronic dimmer. Wire installed next to another wire will pick up some voltage, though. Millivolts is all I've ever seen, except in the case of fluorescent light ballasts, though. Don on August...
Additionally, improved technology means that the initial cost of LED lights has been dramatically reduced over the past few years, removing what has been the main barrier for many business owners.There are four main advantages to using LED lighting for commercial signage as opposed to fluorescent ...
size. While larger gauge wire can actually help an amp work a little easier and cooler when driving speakers by lowering cable impedance (resistivity), the impact on signal cables is negligible. That is, it’s inaudible to anyone who didn’t pay a lot for a fa...
Never wire a regular dimmer to an older fluorescent light fixture that is not rated for dimming or a fixture which has CFL - Compact Fluorescent Lamp adapters. Dimming non-compatible fixtures or lamps will cause the fluorescent lamps to over heat and burn out prematurely. ...
How to Replace a Ballast Things Needed Voltage detector Screwdriver Ratchet wrench/Nut driver Wire connectors Replacement ballast 1. Shut off power to the fixture. Do this by turning off power at the main circuit breaker. Once you have removed the diffuser to gain access to the bulb sockets, ...
And, although UV light has more than enough firepower to make a photocopy, it can be very damaging to our eyes and skin. This is why photocopiers use a plain old incandescent or fluorescent bulb to flash light onto the original document. When the lamp in the copier is turned on, it ...
