Question
Just checking, Is the items I bought meant for direct exposure to the sun, will it degrade turn yellow over time if directly exposed to sun and rain. Many thanks.
So far it works great. Just not sure if the product I have chose n was meant for outdoor application.
Answer
FL140-300 is designed for common usage. We have CP and CG models that is designed for solar.
Material for CP model is PMMA and CG is Silicon on Glass. CG model is higher durability in outdoor condition and high temporature.
