LED Strip Lights

I've got some cheap weatherproof LED lights that are prone to rapidly failing. First a color stop working at first, followed by more colors and finally the LED will not function at all.

At first I thought the urethane covering the LED strip was causing them to overheat, but I just did an experiment on a small section where I slowly peeled back the urethane while the LEDs were on. Just as the urethane is pulled away from the center of the LED, it stops working. Pressing it back in gets it to work again. It seems the PN junctions are exposed and the urethane contact is needed for them to work.

I think the LEDs are not burning out, but losing contact with the urethane over time. My question is, what sort of LED tech requires urethane to operate?

Anyhow, I can't recommend the weatherproof ones since they don't last.
