LED light output will vary with its chip type, packaging method and other differences. But there is no uniform standard to measure its brightness in the world. Generally speaking, the total luminous amount of LED is measured by the height of a light point in the axial direction, and is represented by (MCD) candles. A LED with a very high degree value does not mean that its light output is very high. To calculate its total light output, you must take its luminous angle into account.

Environmental LED is made of non-toxic materials. Unlike fluorescent lamps, which contain mercury, it will cause pollution. At the same time, LED can also be recycled. Durable LED is completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There is no loose part in the lamp body, which makes the LED not easy to be damaged.

In the process of electron transfer, the energy released by high brightness and low heat LED is mainly concentrated in the range of visible light. Unlike other tungsten filament bulbs, most of its electromagnetic energy is concentrated in the infrared region, which makes people feel very hot. That is to say, LED converts almost all electric energy into light energy, so LED is a high-efficient and low heat product.
