I've just worked out that the Thorn SRS fittings (Series resonant start, they don't have a starter but are pretty much instant start) are 44 years old. Based on the same 10 hours per day useage, that's 110,000 hours and I've never known a ballast fail!
My own workshop ( for the repair of Austin 1100's) is lit by a dozen or so Crompton twin SRS 5' fittings. These date from the mid '60's and weigh a ton. Luckily, I have enough T12 tubes to last a lifetime and they don't fail very often. T12's also work much better in the cold then T8's.
Cheers
Nick
