Interesting info, really glad they did the study! However I don't feel it was really anything new or different from what we have been telling people for years. It is nice to see someone else collaborate what we have stated: properly seasoned bulbs - dimming does not reduce bulb life span. I am really glad they specifically called out the burn in period (while 100hrs is excessive or double what we recommend) I guess I am a little surprised the bulb degradation was not as high as I expected after the simulated 1 year time span, I suppose that is because most people run them longer than (going on memory here) 7:15 per day. I expected it to be closer to upper teens to low 20's after 1 of use. I look forward to the "next year" of usage report. I imagine different ballasts would cause different amounts as well. I'd say that would be a good study, but many of the T5 ballast manufactures are out of business so it is probably a moot point. What did you all think?
