I now have to report that one of the lamps has failed entirely. So
that's just 16 months of life, maybe 2 hours a day = 1000 hours. Boo.

Had a 350 lm 4.8W Aldi fail the other evening but this one is on 24/7
and the quoted life of 20,000 hrs is about 2 years 3 months. I'm not
sure when it went into service, for some reason I didn't write the in
service date on it.

This bulb was in an enclosed ceiling fitting and currently the
overnight voltage is around 255, better than the 258+ it got to the
first night after they started line work and rerouted the 33 kV feed
to the local substation. We did drop below 253 (the upper limit) for
a few night but it's gone back up again.
