 I'm talking of course about artificial illumination.  (Yes, again.)
Not sexy?  Too bad.
 Recently a conventional light bulb that had escaped my purge revealed
itself by dying.  I replaced it with the latest generation of Philips
LED bulb that requires about 1/14 (!) as much energy for the same
light output and is specified with a lifetime of 50.000 hours, which
amounts to some 50 years of average use.
 Today I replaced two fluorescent tubes--one had died--in the kitchen
with LED tubes.  Those require 1/3 the energy and Ledvance specifies
them with a lifetime of 75.000 hours.  You do the math.
  From a 20th century point of view, those figures are totally insane.
When cheap LED lamps became common a few years ago, I thought that
was the end of the line, but even LED lamps have made significant
further progress in beam angle, energy efficiency, and lifetime
within just the last few years.  Anybody who is hoarding lamps for
use in a few years will be sitting on obsolete technology in no
time.  Buy today, weep next year.  Between the crazy pace of progress
and the ever absurder lifetimes, keeping spares around no longer
makes sense.
 It is utterly stunning progress.
I am having to replace my 100 watt equivalent 15 watt actual LED bulbs in my office building every three years or so.   I have about a hundred light fixtures in can lights, both inside and outside (mostly inside). I use the lights about 50% of the time.
Evidently, the LED bulbs in the can lights is causing the LED electronic circuit board to overheat since the bulb is upside down, base up.  Many of the LED bulbs that fail have discoloration and cracks in the base.
So 50% X three years X 8760 hours / year = a life of 13,140 hours per LED bulb.  My previous usage of incandescent bulbs was a life of about a year at most.  Plus more heat for the air conditioning and electric bill for the building.
I have some 150 watt (70 bulbs) and 200 watt (90 bulbs) LED light fixtures inside and outside my warehouse, about 20 of them.  I have yet to have any failures on these.  They do have a huge heat sink on them as the fixture weighs about 13 lbs.
