Those chookfest bulbs are doing just what I'd expect from 12V bulbs
in a 28V circuit -- way too bright, and then a drastically shortened
lifespan. (The right bulb can last for years; the wrong one for
I'm not a big fan of the surgery involved in LED conversion, though
I understand why folks do it. Particularly if they, like Emil, have used
the wrong bulbs and found themselves replacing them all the time.
Somewhere, I have Oshino's write-up about bulb rated voltage and
bulb operating voltage, but I do remember the lifespan varies as
some power of the ratio, and it makes a huge difference. (There
are also formulae for derating brightness, etc.)
