The outdoor SD series 

Features: iron box, cheaper than aluminum box, public mold, delivery time is better, many P have inventory, cost-effective

Maintenance: After maintenance, there needs to be a 60-80cm maintenance channel.

Heat dissipation: Because you want to do waterproof, heat dissipation capacity is not so good, the Middle East or very hot places should + air conditioning

Brightness: 5000-6000CD/sqm, brightness mainly depends on the equivalent chip size, the larger the size, the brighter the brightness

C series National Star copper wire 6000, National Star gold wire 8000,

Now it’s P5, P6, P8

Power: The maximum power is 900W/sqm outdoors and 600W/sqm indoors.

The average power consumption is 1/3

Power consumption is expensive, such as Germany’s electricity is particularly expensive, you can push the common Yin scheme

Common cathode solution: reduce power consumption and heat dissipation

Common negative power supply: double brush out, reduce heat dissipation, IC, power supply, lamp beads are not the same, mainly the power supply method is not the same.
