A three years has been passed since these LED tubes were installed on the 36W T8 battens, and still all of them have uneven brightness like this. One of the tubes flashed, and one didn't worked at all. I've seen only a one very new tube that lighted smoothly.
As the result, the light level in the parking lot, is very low.
In general, these LED tube can be considered EOL, despite they still operating, because they produces very little light.
