I replaced one hard-to-get-at bulb at my parent's house with an LED bulb some time ago. So far, it's working great. I'm not expecting to need to replace it ever again. And, if the new bulb saves my Dad from teetering on top of a ladder, perched on a chair, perched on a stack of phone books, because he "doesn't want to be a bother and call me to change it" ..... then frankly I don't care what it costs.
But, I'd say that, at 20 bucks or so a pop, they're not yet ready for prime-time, quite yet. Hopefully in a few years.
“So far, it’s working great. I’m not expecting to need to replace it ever again.”
Don’t be too sure. Two years ago I bought a 5 watt LED spotlight at Walmart for my front porch. It had a large cluster of LED’s. Since LED’s are are low voltage, the light also contained electronic circuitry to to step down the power from 110 volts AC to to low voltage DC. The circuitry gradually failed within months, one LED segment at a time. So, even though the LED’s may be touted to last a long time, the power supply may not. Great Chinese product, huh?
