Thanks. Fluorescents are cheaper, but I have decided on the
Costco leds.
They may be cheaper to buy, but the LEDs will be a LOT cheaper in
the long run when you consider their energy consumption AND their
life expectancy.
I don't buy the advertised life of any lighting. I just and another
pig tail die today. I've lost more of them than incandescent bulbs
in the last five years, despite being outnumbered at least 3:1.
But it's not even a debatable issue.
My LED's have already outlasted any fluorescent tubes I've ever had by
at least 2 fold.
I would bet the farm that I'll get another 10 years out of them.
A safe guess would be 20.
But 2-fold isn't anything close to the advertised life. We'll see but
I *highly* doubt you're going to get 10 years, much less 20. Heat is
a killer of semiconductors and those LEDs run *hot*. If you want to
extend the life of the medium screw base LED "bulbs", a beer-can
heatsink (cut it up to look like a fan radiating away from the base)
will probably double its life.
I've never had a tube last more than 18 months without starting to fail.
