A few of my church buildings have 1970s vintage Sylvania Lifeline F40T12 in some of the closets, that rarely get used.  I've pulled these out to add to my collection and put in newer T12 tubes.  I have quite a number of Philips, GE, and Sylvania (and some off brands) from the 1980s and early 90s as well.

I just changed out 2 1997/98 vintage EoL Philips F32T8 700 series 3000K  tubes last night at one of my buildings. These were the first gen Altos and they lasted quite well.  This was the only series of Philips Alto tubes that I have been impressed with.  Sadly, when Philips converted things to the Alto line, their T8s really suffered for durability when it comes to their cathodes.  The cathodes have always been very weak in the Alto T8s and many would break off at the ends, rendering the tube useless after a few minutes or hours of use.  I've dealt with hundreds of these.  As the Alto series progressed, it seemed that so did their weak cathode issues.  The cathode guards were fine, and sometimes these guards would extend the life of the broken cathode tubes, and sometimes they would even run so hot during EoL that they would melt the sockets or occasionally even blow an electronic ballast fuse.   

My supplier stopped selling the Phillips tubes because of the weak cathode issues and all the returns he would get.

The Philips Alto series has a long lifespan of around 45,000 hours. The nominal life of my T10 lamp is only 6,000 hours.
