You might want to rethink the covers on those lights. Heat is the number one issue with LED's and those with the proper drivers will reduce light output as heat increases. You will notice the rear of the light is a finned heat sink. That is there for a reason.
Your plastic might act like an insulator on the light and prevent it being able to shed heat while in use.
I did an experiment with one of these lights and filled the body with epoxy to make it more shock resistant.
It died (thought it might) and was due to the heat soak. Mind you this was no fault of the light I did something to it that went way beyond its design so the fault lies with me.
