Generally speaking, LED is the optimum option for lighting retrofits. LEDs have longer lasting life times and consume up to 80% less energy than traditional halogen light source while producing same amount of light. There is a table of the comparison of the main characteristics between incandescent, halogen, fluorescent and LED.

From the table, we can know that LEDs are better than traditional light sources in certain factors.
- LEDs have wide CCT (correlated color temperature) range. Different color temperature brings various feeling and atmosphere.
- LEDs have higher efficacy than traditional lamps, which means LED can emit more light with the same power consumed. The total cost of LEDs is very low compared to other conventional light sources. Choosing LEDs can help you save money.
- LEDs can lasting up to 500,000 hours, significantly longer than other traditional light sources. LEDs are durable as they are just slowly lose their light output over the time.
- LEDs can not only apply for indoor but also outdoor. Some of them are equipped with outstanding waterproof, dust-proof and corrosion resistance ability.
- LEDs emit light with little UV (ultraviolet) and IR (infrared) radiation, which makes them widely used for the goods that are sensitive to heat and the materials subject to UV degradation.
- LEDs are environmental friendly because they are free of hazardous chemical content, such as halogens, mercury and neon. They are also more safer to users without hazardous chemical content.
- Unlike other traditional lamps, LEDs turn on instantly, no waiting around to warm up, reaching full brightness rapidly.
