…the contractor-grade FEIT incandescents installed when we built our house enjoyed a MTBF of about five years; the FEIT halogens (‘high-efficiency incandescent’) i stocked up to replace them after traditional incandescents phased out are on the order of six months MTBF…
…while i question whether the manufacturing and distribution of ten fourty-watt halogen bulbs really emits less carbon than one sixty-watt incandescent running for the same duration, at least the spectra are unchanged: i’ve yet to find any LEDs which offer acceptable black-body spectra and i specify the things professionally…
Every halogen bulb I had, claimed twice the life of a typical incandescent. I’m not disputing your experience because we were inflicted with some godawful trash, just that the carbon expectations were likely made on these claims
…my experience before ‘high-efficiency incandescent’ halogens was the same: i have thirty-year-old proper halogen lamps either still going strong or which have been replaced only once over that period…these little A19 halogens, though, have an such absurdly-short duty cycle that they’re viable only by virtue of stocking up dozens of cases for pennies on the dollar when they were phased out a couple of years ago…
…i do hope that we have respectable consumer bulbs available in perhaps five years after those few hundred halogen bulbs are gone, but i’m not optimistic as poor spectra appear inherent to LED technology and the market seems to have settled on ‘good-enough’…proper incandescent bulbs are of course still available for specialty applications, but they’re not easy to get…
