4 years average
I get on average 4 years out of these. I write the date on them when they are installed. I do this with all the bulbs I install. If one burns out quickly I know that I might have a Ballast problem. I replace around 300 bulbs a year, 13 different types in 7 locations. So writing the date really helps.

I am very satisfied with this transaction. Two of the bulbs arrived broken. I completed the required documentation to report this. Replacement bulbs were received immediately. All other 18 bulbs were working just fine. Thank you.
