Over the past years, incandescent light and fluorescent light occupied the main traditional lighting market. Lighting technology advances with the times, LED light fixture seems to stand out.

How dose these light fixture work? And what is the difference between them?

Incandescent lamp (Incandescent light bulb) is an electric light source that energizes and heats the filament to an incandescent state, and uses thermal radiation to emit visible light.

Traditional fluorescent lamp, the low-pressure mercury lamp, uses low-pressure mercury vapor to release ultraviolet rays after being energized, so that the phosphor emits visible light. Therefore, it belongs to the low-pressure arc discharge light source.

LED light, a light-emitting diode, means that a solid state semiconductor device convert electrical energy into visible light, it can directly convert electricity into light.

We can see the luminous flux corresponding to each lamp types of the same wattage, it obviously illustrate LED light more energy efficiency than incandescent light and fluorescent light.

Fluorescent light, incandescent light and LED light, which is more cost-effective?

Compared with incandescent light, fluorescent light and LED light more energy efficient. Nowadays, LED light lifetime can reach 50000h, but lifespan of fluorescent light just 8000h, the upfront cost fluorescent light is $2 per bulb about half the price of an LED. In the long term, LED light will more cost-effective in the later management cost. So we shouldn’t just consider the price of lighting fixture.
