I searched but didn't see this specifically. I've got a couple of really old (early-mid '90s) UK lights with halogen bulbs from when we first got certified and needed lights for our advanced open water certification. I think one has 8 C cells and the other has 8 or 12 D cells, and the things burned so hot they could only be switched on under water. Each has a single halogen bulb.
Has anyone converted these to use multiple bright LEDs? If yes, any tips, pointers, references or directions? If no, any suggestions on doing a conversion, or where to start? I started realizing I could stuff a lot of superbright LEDs into the D-cell light and it would have a long burn time. As it is, these lights have just about no value otherwise and have been sitting in the closet for years
