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.
- Solutions: We will respond to customer problems within 12 hours and solve them quickly. Helping customers solve problems is what we are most proud of.

Extend the life of the lamp
1：Use ECO mode to reduce lamp consumption.
2：Do not exceed 4 hours each time.
3：Each use lasts at least 3 minutes.
4：Do not disconnect the power supply during use.
5：After shutting down, wait at least 60 minutes or the projector has cooled down before restarting.
6：After shutting down, make sure that the cooling fan stops before disconnecting the power plug.
7：Regularly clean the dust inside the projector and around the lamp, and replace the filter.
Bulb life test
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.

This projector is great … the lightbulb went out after many years and we needed a new one … the new one works awesomely.

Used the COOBAN BL-FU240H/SP.7G901GC01 bulb to replace the failed on in my Optoma HD146X. The little screw it came with was too short and would not thread into hole in the lamp housing. I had to remove the screw from the old bulb bracket (thankfully I kept it), and use it in the replacement bulb bracket.Once installed, its a great replacement. The projector is brighter and crisper and like new. 100% recommend as a replacement, just keep the old bulb screw (just in case).

The Cooban bulb assembly was a perfect fit for my projector. My old bulb was getting dim. The Cooban replacement works great. The picture is brighter and sharper. It’s as good or better than the original. I’ve had it in for two weeks. No issues so far. Highly recommended.

Might have just been a dud bulb but it failed in the projector about 3 days after being installed.
