I have had waterproof LEDs from amazon in my T8s for over 3 yrs now with no issues. Super easy to install and clearly marked where to cut to length with scissors. Just have AP cut a groove for them ($5-10) and instal your lights before assembling the top of the enclosure. I think there are pics of mine on my profile from when I set them up a few years ago. 3528 LEDs will fit the 8mm groove AP cuts for their lights. They fit very snuggly, I didn’t use any additional adhesive to keep them in the groove aside from the adhesive on the back of the strips in the event that I should need to remove/replace them. In my other enclosures without recessed grooves for the strips I secured them using the Lexel sealant that comes with AP enclosures.
