I just replaced one of my Finnex Fugeray Planted+ LED lights (48"). This unit lasted 3.5 years working flawlessly attached to a timer (thus, not using the on-off switches) and illuminating a tank for about 10 hours daily. I have 6 more of these units 36-48". I love them!
The light actually still works, but sometimes (often) its intensity is very low, and a few hours later it may increase (or not); as is, I deem it unreliable and it may just quit anytime.
Although I am somewhat upset that it broke, I would say I got my money's worth and more.
