Product description “Let there be light, and there was light.”
We are passionate about the business of light bulbs. We also always focus on the field of bulb light source systems. Our light source system fields include projector bulbs, stage performance lighting, 3D architectural projection, lighting systems and so on. The core of products & after-sales
The bulb life: The core of our products is to extend the life of the bulb. Because it’s easy to increase the brightness, and many businesses can do this.Production core: The core of our production is to produce big data. Through continuous collection of big data, engineers solved the problems of incompatibility, failure to start, and low brightness. High-quality raw materials are important, but production matching data is more important.Solution: We will respond to customer problems within 12 hours and solve them quickly. Helping customers solve problems is what we are most proud of. Bulb model: RLC-127

We have a team that specializes in testing the service life of bulbs. Engineers will test the bulbs in different series and different environments. At the same time of testing, we will collect the data generated when the bulb is working, and update the bulb technology based on these data. Brightness test
We implement a unique policy for the brightness of the bulb, the brightness index difference of each bulb is within 4% to ensure the consistency of the brightness of each bulb. Color temperature test
We ensure that the consistency of the color temperature index of each bulb reaches 100%. and the color temperature remains unchanged within 3000 hours, the color temperature difference within 5000 hours does not exceed 2%. Technology Application
We share light source technologies in different fields. for example, we apply the light and shadow technology of 3D architectural projection to projector bulbs and stage lighting.Lamp Life：Increasing the brightness of the bulb seems to be an easy task,The most difficult thing to break through is how to extend the life of the bulb.We did it.
