All our LED neon flex is constructed using silicone rather than PVC. Silicone is more resistant to weathering from extreme temperatures and UV exposure, meaning the material will not yellow or crack. Silicone material also offers better thermal conductivity than PVC, allowing higher powered (brighter) LEDs to be used.
Our neon flex can be sold as cut lengths with soldered flyleads and glued end caps, or by the roll.
