This is quite an interesting page I found on the subject of lighting very high ceilings but the interesting point is way down on the page.
It suggests that unlike all other fluorescents T5HO uses a 'programmed start' electronic ballast and will only degrade (lumenwise 5-6%) over its lifetime!!!
The others are on 'instant start' electronic ballasts or magnetic 'flicker' ballasts which as we know do reduce lifetime.
It also suggests that MH lights degrade a lot quicker too!!!
Any thoughts? Please note we are talking T5HO here and not T5.
