Security Outdoor Solar Motion Sensor Light 10W 20W COB LED

Purchased the 10w sensor light around 2 years ago and have been pretty happy with the quality and performance except for one thing and that is for such a reasonably expensive light, it uses the same type of sensor as a $20 light and the plastic fresnel lens on the sensor disintegrates over time which then stops it working. Thankfully I was able to find spare sensors on eBay to replace the existing sensor which then required a bit of fiddling/soldering to replace it but is now back up and running
