Jury is still out on that one.
I've had to replace several CFL's. It's always been the driver
electronics that smoked.
LED drivers have lower output voltages, but the input side has much
the same vulnerability.
25,000 hour LED life is meaningless if a power glitch can take out the
Time will tell.
Heat is the enemy. When venting around fixture is poor CFL always fails
premature. Yes, electronics failure. So far none of LED bulbs failed in
my place going on almost a year. I expected ones on the GDO in the
garage would go first(vibration) but they are still working yet.

If they last long enough to recover the upfront $$$. From what I've seen
with the claims made on CFL versus how long they really last, and how fast
other crap consumer stuff fails these days, I'm not going to be the one
to find out.
I have not had any problems with CFL's interfering with the radio, but
they usually have an electronics failure long before the tube goes bad.
When I started using the LED bulbs, radio interference with Two Meter
Ham Radio became a serious problem. Dimmable bulbs seem to be much
worse than non-dimmable.
I installed a 60 Watt equivalent LED bulb in a staircase where it is
hard to access the fixture. That fixture's wiring happens to make a
good antenna, so I had to try several bulbs to find one that did not
interfere. That bulb is a Phillips non-dimmable. Another that had only
a slight amount of interference, was a cheap WalMart soft white
Well, I just found out that my local Home Depot sells LED bulbs with a
candelabra base. They're only 25 watt equivalent (compared to the 40
Watt incandescent we have now), but they're dimmable. But, they cost
$17 $Cdn each, and that's pretty pricey if I have to buy 6 of them.
The guy at Home Depot says that the package says "dimmable" on it, but
that I may have to replace the dimmer switch anyhow because old dimmer
switches might not work with the relatively new LED bulbs.
But, he also said that Home Depot here in Winnipeg has only been
carrying LED bulbs for the past 4 months or so, and he's seen a steady
decline in the price of LED bulbs over that time. Every month or two
there's a drop in the price of the bulbs they're getting in of about $2
on a formerly $20 bulb.
He also said that 60 watt equivalent LED bulbs with the medium Edison
base were down to $12 each now, and given their long life, it might make
sense for me to replace the CFL bulbs in my hallways with LED bulbs. I
wouldn't replace them all at once, I'll just start buying spare LED
bulbs to replace the CFL bulbs I have now. He also said they have a 100
Watt equivalent LED bulb, but it costs $27, and that's still a bit too
pricey for me.
Consider yourself lucky you don't need 42 of them!!!
Just relamped a large chandelier at the office.I sold them for $9 each
and still made a small profit. Imported them myself from China..
Needing 42 I had to buy 50. Dim fine on a Lutron dimmer. (but only to
about half bright - the dimmer can't reduce the output any farther)
Can you post which Lutron dimmer you purchased and whether or not it
worked properly with LED bulbs. If I'm going to have to replace a
dimmer switch, I might as well get one that I know works.
I know the dimmer I bought for my mom's dining room chandelier barely
fit in the electrical box. Are the new dimmers smaller?
Haven't bought them yet because nobody keeps in stock the color I want
(Ivory must be out of fashion now, but that's what I want to match the
existing switches and outlets), but what I am looking at is the Lutron
Maestro C.L.* These are programmable for minimum and maximum light
level, fade-to-off delay, and... (I forget the other options). They are
large (I've seen other colors in the store) and would be a tight fit in
a single-gang box, but I assume that they must be NEC compliant. About
$30. The Diva models look similar and are a little cheaper, but I don't
think they are as programmable.
*MACL-153M-xx (where xx is the color code).
I now have Lutron Maestro dimmers installed for both the dining room
(four Feit BR30 LED bulbs) and the living room (eight Feit BR30 LED
bulbs). Haven't really had the living room ones on for more than a
minute or two, but one or more of the dining room ones -- one at a time
-- will change brightness from time to time. (These specific Feit bulbs
are listed as compatible with that Lutron dimmer on the Lutron Web site.)
I've had the Maestro's installed for over 10 years, and I'm currently
using one of them with all LED bulbs (PAR-30's, for the most part).
One should treat the switches gently, a soft tap is sufficient to
activate the switch. Hard taps can break internal plastic bits
that disable the main switch (fortunately, when this happened,
I called Lutron and they sent me two new units gratis).
They're available in 30 colors (including ivory) on amazon for $28.75 each.
