Common-cathode Advantages
Adopt common-cathode solution, power to Red / Green & Blue LEDs separately and reasonably to reduce the power dissipation.
Low temperature rising , Energy-saving , great color consistency
Low Temperature Rise, Low Heat
Under the same condition, the temperature of common-cathode LED
is around 25% lower that of common-athode LED
Low Power Consumption, Environmental Protection
Adopt dual channel power supply tech.
based on different optical characteristics of RGB LED.
With smart IC control system, it distributes precise voltage
to LED and driving IC saving 20% to
30% energy.(Comparing that with common-athode LED)
IP65 Protection Level
Common-cathode solution saves energy and
have great dust-proof and waterproof effect
