I use the 5m Led Strip to my aquarium to illuminate, because I had no desire to squander 2X 58 Watts per hour..
After a few weeks of testing I can only say good no problem with water / moisture and the Aquarium (2mX50X50CM) is completely illuminated with this strip, and much nicer than before.
My AQ lighting now consumes 18 watts per hour.
