30mm thick Fluorescent Clips

These are clips I used in My Philips ceiling light where I replaced the (TL5C) 18mm thick circular 300mm TL with a 30mm thick LED ring replacement.

These clips are a in place replacement. I got the replacement 300mm LED ring from Aliexpress, it wasn't really a common item. It ended up just as expensive as a new fluorescent, which is odd.
