.You may have to remove all your Edge-lit led panel light from your product list as it takes problem after 1-2 years
As you know,some led panels will be yellowing after working 1-2years,
because they are all edge-lite series with LGP(light guide panel) inside.
However, most of LGPs are including PS more or less, which is the root cause of the yellow color.
BGT Back-lit panel is using lens to instead of the LGP, which can make higher light efficiency
and more even light than similar products. Meanwhile, we can offer a 5 year warranty
So if you have some replacement projects, BGT' Back-lit panel is the best choice.
Below is some simple comparisons for your reference:
More details will be forwarded if required, thank you!
Nice day!
