--These have high failure rate -especially the controller
if you mean the UT controller which integrate the 200W power in it . yes, the rate is higher than 20% after 3 years.
There are 2 or 4 60 watter power module and a mcu and a screen and a fan. no matter which part is broken, the controller is "failure".
please consider the controller run every hours for many years. not like TV or washing machine.
Please you can compare with your office lighting, it is only 8-10 hours. how many light broken after 6 years?
Please it not means we should stop improve it. in fact, we develop a new structure of the controller, there is no fun and power. the fail rate is as following .
1, 1.2% at first open package.
2, 0.3% in first year.
3, less than 0.05% in 3 year
The reason of 1.2% is because shipping problem.
1, screen connect loose
2, screen damage
3, CPU connect loose
4, others no-human damage (less than 0.1%)
One advantage of our light is the price. it is because we ship it from China directly. save almost half cost.
the disadvantage of shipping is broken during the ship.
I think it is our mistake, we should design a more strong connection way. please we are improving it.
The 0.3% is almost all screen. there is line in the screen or no screen.
Please we completely understand the trouble of fail, contact us, we will help you solve it ASAP.
Sorry again for that.. ....
