Here is the solution you seem to be looking for to eliminate LED reflection. Goto ebay and type in "Carplite" in the main search box. They sell HPS or Green colored filter covers for 50W LED lights. Also have Custom sizes if needed for other types of light frame sizes. I used them and made a world of difference. I bought one at first just to try out and bought ten after that. Got the best worlds of using LEDs with the color of HPS to better penetrate the water and reduce glare. They are made from transparent plexiglass so much much more durable than tint/film. And you can easily remove these in seconds if you want the bright light back for clear water. Much cheaper alternative than going HPS with all the extra bulbs, capaitors, genny, difficult wiring and weight, etc. Hope this helps, just wanted to share what I have found to everyone who had the same issues I had.
