Advantages of LED lamps over Incandescent lamps2

1, Energy saving. At present, the light efficiency of LED is about 8 times that of incandescent lamps, that means the same brightness of LED power consumption is only one eighth of incandescent lamps, the use of 40W incandescent lamps, to get the same brightness, should use 5W LED lamps. According to the calculation of 3 hours of use per day, incandescent lamps consume 43.8 kWh of electricity per year, LED lamps consume 5.475 kWh of electricity, the above is only the calculation of a single light source, the more light sources, the more obvious energy saving.

2, long service life. the service life of LED lamps is generally 30,000-50,000 hours, much higher than the 1000 hours of incandescent lamps

3. Green and environmentally friendly. It does not contain lead, mercury and other polluting elements and does not pollute the environment in any way, whereas fluorescent lamps contain mercury vapour, which can cause damage to the liver, lungs and brain even in very small doses and is extremely harmful to the human body and the environment.

4、Safety. Lamp shells are mostly made of plastic, high impact strength, not fragile, easy to transport, safer to use. Incandescent lamps usually use glass shells, relatively fragile, while easy to produce glass fragments, not safe enough.
