What are some of the characteristics of a good LED bulbs

Currently, the stability of the LED bulbs need to have the following characteristics: 1) Using high power LED as light source; 2) Good heat dissipation structure, that is, an aluminum frame such as the cooling structure to ensure the droop slower, not the light of the apparent failure, within 2 years 3) High luminous efficiency, can at least

currently, the stability of the LED bulbs need to have the following characteristics: 1)

Using high power LED as light source;

2) Good heat dissipation structure, that is, an aluminum frame such as the cooling structure to ensure the droop slower, not the light of the apparent failure, within 2 years

3) High luminous efficiency, at least 40 w can replace the traditional incandescent lamp;

4) Not easy to dead lights and electric leakage, etc.
