A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.

how do you test a single pin fluorescent bulb?

Set a multimeter to the ohm (Omega symbol) setting, then touch one tester probe to each of the pins at the end of the bulb. If the tester shows a reading between 0.5 and 1.2 ohms, the bulb has continuity. Repeat the test at the other end of the bulb.

how is a fluorescent light wired?

To work well, compact fluorescent lamps need to be used in lamps with polarized plugs, where the large prong on the plug is the neutral and is wired to the threaded shell of the bulb socket, and the smaller prong on the plug is the hot and is wired to the brass tab in the bottom of the bulb socket.

how do fluorescent bulbs work?

Fluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted into standard visible light using a phosphor coating on the inside of the tube.

How do I know if my fluorescent starter is bad?

Return fluorescent bulbs to the socket if they were removed to reach the starter. Turn on the switch. If the light comes on and doesn’t flicker continuously, the starter was the problem. If the fixture doesn’t light or continues to flicker, the problem lies elsewhere.

Can you still buy t12 bulbs?

Also effective July 14, 2012 the US Government will make lamp manufacturers to discontinue T12 lamps so if you just have to have T12 lamps you better buy a couple of cases. U-shaped T12 lamps, many 8-ft. T12 and T12HO, and some low-color-rendering 4-ft. T8 lamps will be eliminated.

How do you remove a fluorescent light cover?

How to Remove Fluorescent Light Covers Clear the area of the floor below the light fixture whose cover you want to remove. Grip the upper lip of an acrylic cover at one side of the fixture with your fingers. Work from the stepladder. Loosen and remove pan-head screws, using the appropriate screwdriver.
