I have used "waterproof" led strips off of eBay and amazon such as (eBay Link), they do work for the most part but are bad for being submersed or exposed to very wet conditions. I was thinking of putting the strip into some aquarium style tubing such as this (Home Depot Link) and simply sealing off the ends with some wax or thick glue. The only thing I am worried about is heat build up as some strips use around 3 amps for 15 feet, which can get quite warm to the touch. So the real question here is, Do you guys think it would be okay to just leave air in the tube? Could I possibly fill up the tubing with mineral oil or some similar substance? is there a better way to make these strips submersible?
Thank you guys for your help!
