Yes, well, that's /always/ the excuse, isn't it? "You bought the wrong

Fukushima was designed properly; it just wasn't positioned too well.

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.

This is a combination of them being upside-down (and even the crappy ones
say on the datasheets that they can be used in any direction, even though
they usually can't) and the design of the cans which are intended for
incandescents.

Look for the Cree lamps that are marked "Good for Enclosed Use."  They will
run twice the cost of the cheapies but last much more than twice as long.
(And of course the labour for relamping gets saved too.)
