I bought these lights approx 12 months ago & normally I'm not one for writing reviews, however as I was giving my pond a spring clean and finally pulled out the lights that gave up the ghost many months ago, I felt the need to warn anyone against buying these lights. Initially, when I bought these lights they were fine. All was well until after a couple of weeks 1 out of the 3 lights stopped working completely. I was a bit cheesed off, but to be honest I couldn't be bothered with all the fuss of getting them out of the pond & sending them back so I left the other 2 working lights to do their thing. About 2 months later, the 2nd of the lights began breaking down and slowly but surely the individual bulbs stopped working and within 4 months of purchasing all 3 had died. I know these lights were only budget so you shouldn't expect too much, but if they don't work as underwater lights then this should be clearly detailed on the packaging - they are clearly NOT water-tight. I'm back in the market for some new lights & think I might spend a little bit more & get some decent ones - don't waste your money on these.
