Why every 5 years? I have been looking into LED lights and I have read from some sites, 3 years, some say 5, others says when they burn out.
My understanding from using LED's with sign installations for commercial businesses is that LED's wont technically "burn" out but they do fade over time, most LED's I have seen are rated for 30-50,000 hrs of burn time which is well over 3 years of light if ran 24hrs a day, 7 days a week. The spectrum of the LED wont change either due to how they are made, if it is made to produce blue it can only ever produce that colour. But white LED's are made with phosphurs which turn a blue led into a white one, so the white will change to become blue over time but that doesn't seem to make me want to replace the whole unit every 5 years.
Just curious as to what everyone else thinks on replacement time?
