Anyways, I think what I was trying to say was that while you may experience a 25% loss in one year, I, as well as a few others, have experienced less with HQI/M80 ballasts.
I agree, your experience does suggest that. It is an interesting finding and it would be useful to have more side-to-side comparisons to see if it really holds true. I'm not necessarily a proponent of electronic ballasts. They're just what I happen to have. Frankly, I don't know that they live up to all their hype, but that is another issue.

Maybe when it's time to replace my bulbs I'll spring for 3 HQI ballasts and compare 4 bulbs on IC ballasts to 3 on HQI over a year.
