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.

If it saves enough money to pay for itself (including, to be sure, the
labor costs for replacing them), then using them makes business sense.
Even if the asserted life is hooey.

Perhaps there are can fixtures designed to use LEDs.

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.

Currently unavailable -- but others are shown further down the page.

The size was interesting -- 17 x 15.7 x 2.4 inches
(length/width/height). That's a lot of light in a small package!
