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

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.

I installed this lamp in my Panasonic PT-AE4000 projector. It is super easy to install and it was a perfect fit. It provides a brighter picture than the last lamp I had, which I paid 3 times as much for! It comes well packaged and they even provide a screwdriver and a protective glove to wear. I recommend wearing the glove while handling the lamp, because finger oils can reduce the life of the lamp, even on the back of the glass.

Our original bulb lasted 7 years and in the last year or so it started to fade. I ordered this one given all of the positive reviews. Upon arrival the new bulb was amazing for a few months, now, less than 6 months in the bulb has faded. Not sure if there is a warranty (perhaps I can get a replacement), but the bulb has failed. The colors are washed out. Going to get a bulb from another source.

Purchased just before Christmas, had only been used for about 20 hours and the lamp died. Worked with customer support and received great support and a replacement lamp.

Probably the best option as replacement for my Optoma hd143x. Lasted me over a year using the projector 10-14hrs a day as a replacement for tv. Hopefully this 2nd one I ordered will have the same result.

I was happy to see an actual Osram bulb inside and now my projector is bright again - thank you Cooban. My last replacement bulb from a more expensive company was not as good a quality so glad to have found this one.

This bulb was to replace the one in my Optoma GT1080. The bulb recently was replaced by a generic one (returning right away) and decided to give this one a shot and as soon as the picture came on screen, it was beautiful, bright and very vibrant. It actually reminded me of when I first bought the projector. Hoping it lasts as long as they say.Great, great item.. Glad I now have a reliable brand to go to in the future. You will be pleased with this one!

I received the bulb and realized that it matches the original part while it does not match the photo in Amazon.However when I tried to install it, I found that the power adaptor does not work -- when inserted in it is loose. It turns out that the two pins are smaller comparing to the original part. Also it can be inserted oppositely which is another problem.I had to replace the wire from the original part to get it to work!!! Once it is back to work, the light and quality of picture looks as good as before (probably brighter, since it is new).

This lamp was easy to install into my Panasonic PT AE-4000 projector in our home theater in our basement. It is a dark area with padding on the walls and 7.1 speakers. The old lamp had burned itself out and stopped working. This lamp was reasonably priced, easy to install and brought back the brightness and clarity that we previously had. I recommend this lamp!R.
