As LED market and technology matures, more and more kinds of LED products, quality is getting better and better, but price of LED products in the market now is more and more don't understand, often the same product price will be a difference of more than a dozen yuan even several dozens yuan, do you want to know the secrets of the middle? And look small make up for everyone to do analysis: 

First of all the main the main part of a guardrail tube of the main: lamp bead 

 

LED product price difference reasons: light beads: 

 

Common on the market failure control more better lamp brightness and light bead price in 0.36 0.43 yuan/set of RGB price is 0.2 / set RGBLED application Angle analysis: 1. The former high brightness long life droop small melange effect better dead light rate is low, the latter is brightness low droop obvious uneven color mixture of shorter after 50 ma impact test (conclusion) both the price of each of the guardrail tube on the application differences in 7 to 8 yuan. 

 

LED products price differential reasons: circuit board: 

 

Circuit board, can be divided into fiber half wave fiber flame retardant cardboard difference? 

 

Wave fiber board: flexible well is not easy to break, the damage of the original device is small, long life, copper thick and over current. 

 

Board: just the opposite, if you have any strong vibrations during transport or installation may be so, copper thin, easy to cause in a tin copper phenomenon, even time will corrupt or tube with water vapor. So on the circuit board can save 0.5 1.2 yuan. 

 

Line: should or shouldn't want to now, there has been much debate, of course, add to it is good, is of course the over current is larger, if is 220 v with a 15 m should be a joint problem is not big, do not add words can save 0.6 yuan.
