“Great light, instant on, very bright and robust. It is fitted in garage and I have knocked and broken glass fluorescent tubes. This LED tube is robust with a metal spine and plastic surround and is well made, I doubt a knock would damage it. On my lights it was a simple retrofit of the led tube and starter. Only thing to watch it is very snug in the fitting. My previous 5 foot tube was 1498 mm this being 1500 mm makes tight but not an issue.”
