You've actually had an LED bulb die on you? Was it always on?

I hope so. Having worked in the semiconductor industry, I know what they do to

Hopefully buying at Costco helps. They should take them back if they fail early.

The Christmas lights still aren't affordable given the amount of use.

LED Christmas lights look terrible too

Agree, but I think they are getting better

This is the first year I've seen some that look halfway decent.

Same. My neighbor got some clear C9 LED replacement bulbs that he is working

The thing I like about LED strings is that you can string together like 100 of

This sounds crazy. Who spends $800 a year on lightbulbs? $66/mo?

I can tell you who doesn't anymore...workindev.

Buton777

That is light bulbs + energy

workindev

1/7/14 12:42pm

ahh, gotcha.

Here is the math for a single 60W bulb at 1 hour per day for a year

workindev

1/7/14 12:50pm

So LEDs cost about about $4.00 for 10hr/day/year ... if I did the math right?

I've had CFLs go out on me, but I have more confidence in LEDs.

1/7/14 1:24pm

There was a 100W equivelent floodlight at Costco

workindev

1/7/14 1:31pm

Nice ... $24 light bulbs

1/7/14 1:36pm

Glad to hear the Costco bulbs look good. I saw them last week and almost picked

So you can use the dimmers with these ones?

Iman23

1/7/14 1:01pm

yep.

jdub

1/7/14 1:03pm

Yes, but it doesn't get quite as dim. Probably down to maybe 25%
