Lamp dimmers, sold online and in hardware stores, come in a few different varieties. They are intended for controlling different types of lamps, from incandescent to compact fluorescent (CFL) to LED, so it’s important to pay attention to the specifications. These are the main types of lamp...
The central element in a fluorescent lamp is a sealed glass tube. The tube contains a small bit of mercury and an inert gas, typically argon, kept under very low pressure. The tube also contains a phosphor powder, coated along the inside of the glass. The tube has two electrodes, one ...
In the last section, we saw that mercury atoms in a fluorescent lamp's glass tube are excited by electrons flowing in an electrical current. This electrical current is something like the current in an ordinarywire, but it passes through gas instead of through a solid.Gas conductorsdiffer from...
They even make an ideal lamp for SCUBA divers and campers. But how do glow sticks work? While it may seem like supernatural magic, the technology behind glow sticks is actually very simple. Let's look inside a light stick to find out how it gives off such a strong light with no bulb...
A three-way switch has three terminals, and the switch connects the first terminal to either the second or the third terminal, as shown here: You use two three-way switches to control the light, and wire it up as shown below: In this diagram, a normal piece of wire comes from the ...

A conductor is a material through which electricity -- a flow of electrons -- easily moves. The entire copper core is coated with an even layer of phosphor lubricant. Phosphor -- like the kind in light sticks and other glow-in-the-dark products -- is the key to electroluminescent wire....
lamp base, you may need to modify it to fit the electrical components. This could involve drilling a hole for the wire to pass through or cleaning it to remove any residue or dirt. For items like globes, be cautious and select bulbs that don't emit too much heat to avoid fire hazards...
and the wire filament in a lamp all give off light, but they also give off heat. If making light is our only objective, any heat we make is wasted energy. If you've ever put your hand near a typical incandescent lamp, you'll know it gets incredibly hot—far too hot to touch, so...
How to Wire a Lamp Post With a Light Sensor Step 4: Turn the Power Back On Replace the track light and turn the breaker back on. Test the track to see if the light comes on; if not, turn the circuit breaker back off and check the fixture wiring. ...
