Ocean LED A3 Pros in water for 3 months with no growth on lens

I just pulled our  2005 Boston Whaler 13 Sport out of the water to give her a wax and was happy to find that the 2 Ocean LED A3 Pro's that were on the back had minimal growth on the lenses. All I had to do to get them clean was wipe them off with a cotton cloth. No scrubbing or polish needed. I am very impressed with their resistance to the harsh South Florida salt water environment. Nice work Ocean LED
