ᐅ Omlöpp LED significantly uneven brightness in display cabinets

See attached photo. The kitchen is finished. Everything is wired. Omlöpp round LEDs in the display cabinets, and as you can clearly see, there are significant differences in brightness. How can this happen, and what can I do besides buying multiple lamps and testing them? Especially since it’s not easy to pull the cables again because it’s an island 🙁

Are there any small films or something like that? But then each would just get darker, and there would still be differences...

I’m grateful for any tips.

It seems to me more like two different color temperatures rather than brightness levels. Warm white in the center, the others cool white. To understand how this can happen, you need to ask the manufacturer in China. Make a complaint and test before purchasing; pay attention to the same manufacturer number and production date.
