We use all kinds of lights in our lives, including incandescent bulbs, energy-saving lamps, LED lights and fluorescent lamps. These lights have their own USES and advantages, and today we'll look at the difference between led and CFL.
LED USES cold light source, low glare, no radiation, no harmful substances in use. LED has low working voltage, adopts dc drive mode, ultra-low power consumption (single tube 0.03~0.06W), and nearly 100% electro-optical power conversion. Under the same lighting effect, it can save more than 80% energy than traditional light source. The environmental benefit of LED is better. There is no ultraviolet and infrared ray in the spectrum, and the waste is recyclable, pollution-free, mercury-free, and it can be touched safely. It is a typical green lighting source. At the same time, LED is a solid cold light source, encapsulated with epoxy resin, which is resistant to vibration. There is no loose part in the lamp body, and there are no defects such as easy burning, hot deposition and light decay of the filament. The service life can reach 60,000 ~ 100,000 hours, which is more than 10 times of the service life of traditional light source.
CFLS are also called compact fluorescent lamps (foreign abbreviation CFL lamps) with high luminous efficiency (5 times of ordinary bulbs), energy-saving effect is obvious, long life (8 times of ordinary bulbs), small size, easy to use and other advantages. It works in much the same way as a fluorescent lamp. Besides white (cold light), CFLS are now warm. Generally speaking, under the same wattage, an energy saving lamp can save 80% energy compared with incandescent lamp, the average life is extended 8 times, and the thermal radiation is only 20%. In the non-strict case, a 5-watt incandescent lamp can be considered to be equal to 25 watts of light, a 7-watt incandescent lamp is equal to about 40 watts of light, and a 9-watt bulb is equal to about 60 watts
