Why does a Rubber Waterproof Flexible Strip Light turn yellow and fall off after being used less than one year?

1. I have purchased a kind of waterproof Flexible Strip Light on the market. After I have been using it less than one year, why does the light's rubber appear yellow color and to be falling off? And it smells after long working time. If you used the light not even one year, could the problem be poor workmanship and bad rubber material of the light? Maybe!
In this situation, it could be that the rubber of the strip light is not of good quality, maybe the product's quality is substandard, maybe ageing or harsh environments like kitchen and boat usage are the reason. It easily gets dirty or dusty in that environment. After a year in the kitchen where you always cook, there will be always oil and dirt around the light. If used on a boat it's the same, there's always water and fishy spray around. This all may cause the changing of the light's color to yellow.

2. Regarding poor quality of the rubber, before purchasing this kind of light, read the product description carefully and check for a good rubber quality without any other materials mixed. To find a seller with a good reputation is very important too, a well known seller is the first choice.
Another situation is that the ageing may turn the strip light to become yellow, break and fall down. Naturally, everything will become old and nothing lasts forever, especially if the application environment is very harsh.
Below are two ageing Flexible strip light pictures for your reference.
