How to use LED lights replace compact fluorescent lamp

Before you replace CFL, You must know that what kind CFL you are using. Buy 120V led compact fluorescent replacement, Buy 230V led compact fluorescent replacement

About CFL: A compact fluorescent lamp (CFL), also known as a compact fluorescent light or energy saving light (or less commonly as a compact fluorescent tube), is a type of fluorescent lamp. Many CFLs are designed to replace an incandescent lamp and can fit into most existing light fixtures formerly used for incandescents.

Compared to general service incandescent lamps giving the same amount of visible light, CFLs use less power and have a longer rated life. In the United States, a CFL has a higher purchase price than an incandescent lamp, but can save over 30 US$ in electricity costs over the lamp's life time.Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal.

CFLs radiate a different light spectrum from that of incandescent lamps. Improved phosphor formulations have improved the subjective color of the light emitted by CFLs such that some sources rate the best 'soft white' CFLs as subjectively similar in color to standard incandescent lamps.

CFL Parts:
There are two main parts in a CFL: the gas-filled tube (also called bulb or burner) and the magnetic or electronic ballast. An electrical current from the ballast flows through the gas (mercury vapor), causing it to emit ultraviolet light. The ultraviolet light then excites a phosphor coating on the inside of the tube. This coating emits visible light.


An electronic ballast and permanently attached lamp tube in an integrated compact fluorescent lamp.There are different standard shapes of tubes: single-turn double helix, double-turn, triple-turn, quad-turn, circular, and butterfly.

Electronic ballasts contain a small circuit board with rectifiers, a filter capacitor and usually two switching transistors connected as a high-frequency resonant series DC to AC inverter. The resulting high frequency, around 40 kHz or higher, is applied to the lamp tube. Since the resonant converter tends to stabilize lamp current (and light produced) over a range of input voltages, standard CFLs do not respond well in dimming applications and special lamps are required for dimming service. CFLs that flicker when they start have magnetic ballasts; CFLs with electronic ballasts are now much more common.

Integrated CFLs
Integrated lamps combine a tube, an electronic ballast and either an Edison screw or a bayonet fitting in a single unit. These lamps allow consumers to replace incandescent lamps easily with CFLs.

Integrated CFLs work well in many standard incandescent light fixtures, reducing the cost of converting to fluorescent.


Non-integrated bi-pin double-turn compact fluorescent lamp
Non-integrated electronic ballast for compact fluorescent lamps Non-integrated CFLs
Non-integrated CFLs have the ballast permanently installed in the luminaire, and only the lamp bulb is usually changed at its end of life. Since the ballasts are placed in the light fixture they are larger and last longer compared to the integrated ones, and they don't need to be replaced when the bulb reaches its end-of-life. Non-integrated CFL housings can be both more expensive and sophisticated.

There are two types of tubes: a bi-pin tube designed for a conventional ballast, and a quad-pin tube designed for an electronic ballast or a conventional ballast with an external starter.

A bi-pin tube contains an integrated starter which obviates the need for external heating pins but causes incompatibility with electronic ballasts.

How to use LED replace CFL:

For the Integrated CFLs, You just plug in LED bulbs.

For the Non-integrated electronic ballast CFLs, If it is electronic ballasts, You must remove the ballasts and then plug in the LED replacement bulb. Otherwise, The LED bulb will be fault. But if it is magnetic ballast (means that with starter), You must remove starter, You can remove ballast either not remove ballast, But if you remove ballast, The efficiency will be more better and saving energy.
