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.

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. 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. 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%. 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.

How should I care for these cotton shorts? These shorts are machine washable. For best results, wash in cold water with like colors and tumble dry low. Avoid high heat drying to preserve fabric stretch and color over time. What material is used and is it comfortable for all‑day wear? These shorts are made from a breathable, flexible cotton-spandex blend that balances comfort and durability. The fabric moves with you, stays comfortable in warm weather or during light activity, and won’t get stiff after multiple washes.
