We ensure the quality of our products

We care about the quality of LED light. That’s why we focus on every detail of every component that makes up a perfect light products.




Low power consumption

The working voltage of LED is 2-3.6V, and the working current is 0.02-0.03A, which means it consumes no more than 0.1W of electric energy.

Long service life

Under the appropriate current and voltage, the service life can reach 60,000 to 10 10,000 hours, more than 10 times longer than traditional light sources.

High brightness and low heat

LEDs use cold light emitting technology, and the calorific value is much lower than the normal lighting fixtures.

Sturdy and durable

LEDs are completely encapsulated in epoxy resin and are stronger than light bulbs and fluorescent tubes. There are also no loose parts in the lamp body, making the LED not easy to damage.


The LED light source can use the principle of red, green, and blue three primary colors,which can generate 16777216 kinds of colors.

Advanced technology

It successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, etc.
