Walmart now selling the cheapest LED "60watt" lightbulb: $8.88

If your cfls are buring out quickly you have some serious wiring and or electric phase issues. That's why they burn out quickly. Got an arc somewhere? That cfl will burn out in a second.. clean electricity and a new cfl will last a very long time. I've been over two years now with my cfls except my security light. I was an idiot and put a cfl in that. It lasted a few weeks. They don't do well in the cold nor on and off type situations. The only other one that went on me was in my garage where I discovered the moron that owned my house previously put flooring over the electric line. That cfl might have saved me from a buring house one day..

The reason you're seeing such mixed results with the longevity of CFL bulbs is that unlike incandescent bulbs, CFL bulbs have a "cooling down" period in-between uses. CFL bulbs need approximately 15 minutes between turning on, and turning off in order to last to their maximum longevity. When you're turning them on, or off more frequently than that they're going to burn out much, much faster.

Personally, I prefer incandescent bulbs because of the warmth and gradient of the lighting they produce. Bulb makers agree, we're hardwired to find comfort in warmly hued lighting.

Do you by chance know what's failing? Is it the bulb or the electronics? Or is it perhaps just the number of operations of the start-up circuitry that's taking its toll, as in, it's good for so many cycles, and that's about it?

It's the bulb. It's turning it off & on too frequently that wears it down. You could get a greater amount of cycles if you spaced them out as opposed to cycling it more frequently than once every 15 minutes. They need a period to cool-down between cycles.

In my case that's horse shit. My burned out bulbs are in a room that has the light turned on maybe once, or twice per evening.

I have seen people try to berate me for having "dirty" electricity or something, but WTF am I supposed to do about THAT? I shouldn't need to fucking rewire my house (or move) just to accommodate a shitty-assed expensive "light bulb".

Then, you probably have an electrical problem. Shrug

Who berated you? Wtf is wrong with everyone? No one berated anyone. Its typicak that homes have shitty wiring. No body does a good job at anything anymore. That's not your fault but you should want to correct it. I found shitty wiring in my 20 year old house. There was no logical reason for what I found other than a moron didnt care or pay attention.

Some of the CFLs out there are absolute crap. I was just reading reviews of some of the off-brand CFL flood-lamps pending putting up an exterior fixture at our barn, and it's clear that the cheap stuff just doesn't last. That's been my experience as well.

I've been using limited numbers of CFLs for a few years now and they die. I stopped replacing them.

As for what fails, I don't know how they are made, but I assume they have caps like most FL power supplies, probably made in Malaysia and probably crap. Cheap, tiny caps would also support the theory of not working well well turned off and back on without a chance to cool. But I've never looked into how they are made and don't care. The light sucks, they suck, I'm not replacing them for most things.

Caps are a common failure point for many electronics. Dell got smacked down by that a few years ago with their GX280 series of computers. About a dozen caps on the motherboard would pop their tops after about 2 years of use.

That's what I was talking about before though, I bet the actual light emitting part for these bulbs is fine, it's their embedded power supply that's failing before it's time. Much the same way the CREE bulbs will fail. The CREE component will still work, just it's PS will fail. They have to build some failure point into the bulbs, otherwise people would replace all their bulbs and then never have to buy another bulb again.
