　　1. Energy saving: LED is a cold light source that relies on semiconductors to emit light, with ultra-low power (0.03-0.06 watts per single tube), 150-200 lumens per watt, light source lifespan of 100000 hours, and light attenuation of 3%~7%. Semiconductor odor detection shows that it does not cause any pollution to the environment, and compared with cabinet tear incandescent lamps and fluorescent lamps, the energy-saving efficiency can reach over 90%. At the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes.

　　2. Healthy: LED is a green light source. DC drive without strobe; No infrared or ultraviolet components, no radiation pollution, high color rendering and strong directional emission; Good dimming performance, no visual error occurs when color temperature changes; Cold light sources have low heat generation (below 60 ° C) and can be safely touched; These are all beyond the reach of incandescent and fluorescent lamps. It can provide a comfortable lighting space while also meeting people's physiological and health needs. It is a healthy light source that protects vision and is environmentally friendly.

　　3. LED lights are small in size, light in weight, and encapsulated in epoxy resin. They can withstand high-strength mechanical shock and vibration, are not easily broken, and have an average lifespan of 100000 hours. The service life of the lights can be as long as 5-10 years, greatly reducing the maintenance cost of the lights and avoiding the pain of frequent light replacement. It can be said to be a "once in a lifetime"
