LED chip quality

Good quality LED is just made of good materials and no saving are done on them. That's why most often the price is an good but not only indicator of LED chip quality. 


Good quality LED features are:

- Thick metal base
Only massive metal base is able to take out the heat to enviroment. The weight of 50W LED chip should have over 20g

- Copper or alu-copper base
The amounts of heat under the LED chips are so huge that only copper or alu-copper base can dissipate heat 

- Branded chips inside
The whole LED chip is made of tiny LED chips made by only few producers worldwide. The good trustfull producers are EPISTAR and BRIDGELUX

- Gold wires
All the tiny LED chips that form one power LED are conncted by tiny wires. Each breake of this wire can breake the partly or wholy LED chip. Thats why good led chip internal connection wires are made of gold

-Fluorescent materials
The tiny LED chips that form a whole LED are covered by the fluorescent materials to amplyfy its power and get the proper color. The good quality fluorescent materials are often branded and produced in Japan
