how to choose led pixel mode
*The size of chip:

The same chip size is large, the brightness is higher , more strong
bearing capacity, stable performance is better, of course the price
performance is better, of course the price
higher relatively，the chip size list as follows:9MIL, 10MIL, 12MIL,
14MIL and 23MIL,etc..
*The efficiency of light eitting, per watt issued LM value is called luminous efficiency. This is an important standard to distinguish whether the led  energy saving.

*The quality of circuit board. The quality circuit board will have an
important impact on the life of the led. The circuit board is divided into aluminum, glass plate, semi glass filber board, paper board Meanwhile Aluminum plate of the best quality. It has best cooling effect,But the cost is too high the led manufacturers only used in high power LED products generally ,Module exposed lamp manufacturers use cardboard Half glass and glass plate. Colorful and full color series have at least use half a glass fiber.

IC(ic control):
*In comparison, IC has a few kinds(such as  ws2801ic), variety of ic are completely different. To take in performance, stability and price are different, resulting in product cost is different.
*Solder: whether the solder soft reflected brightness and ther is no Weldl. This affects the heat and the sign stability.

* Wire:silicagel,containing copper wire.line of ROEN, this is the best line.silica Gel sleeve can withstand oxygenation in a long time,wire body that would be better and soft still, is convenient for the user to install in narrow space, copper can through more current ,not estroyed by large currents. If the wire with UL certification must be reliable quality.

* Shee: the quality of shell can prevent UV, flame retardant .
