Product Description:

Ultra-high brightness light-emitting diode chips AlInGaP and InGaN as a light source, low power consumption, long life of the product, to maintain a reasonable cost products.

Special circuit design, even if the individual LED damage does not affect the normal operation of other LED's, uniform optical distribution.

Using 110-250V constant voltage constant current power supply, wide voltage range.

Incandescent light emitting diode comparison signal lights can save 7-9 times more energy.

Match the existing traffic control logic, light box structure, easy installation.

Features:

High efficiency, long life;

Ultra-thin design, PC material, lightweight;

Novel structure, beautiful appearance;

Moisture, dust; high sealing performance, good waterproof effect;
