This has been my experience also. Just about our entire house in on CFL (twisty) bulbs now, and my experience has been that they don't last any longer on average than an incandescent bulb.

I'm hoping the LED's will last a lot longer.

The bulb I bought has a 10 year warranty, if it fails send it back with the receipt and they will replace it, I plan to collect.

Good news!!! I just found this story on the Blaze!!! There is a loophole for incandescent light bulbs. It seems that heavy duty ones are exempt from the law!!!

Hopefully you won't be able to collect on that warranty Grumpy but I would hang on to the receipt anyhow. They probably bank on the price coming down below the price of shipping long before the 10 years if by chance it doesn't last.
Those rough service bulbs have been around forever, all they bought in the steel mills but I'd bet the price has gone up. They seemed to last just as long if not longer than a regular bulb but didn't seem to give off the same light, they even had some that if the glass broke it was held inside a safety coating. We could drop a 250watt bulb straight down onto a train rail bounce it up & catch it & it would still work. 8-)

CFL bulbs are junk. What people tend to forget, is that CFL bulbs have too many factors that will effect the life of the bulb which is why a CFL will rarely last its rated life. Like mentioned, the weak link with an LED bulb would probably be the circuitry of the bulb. Putting the power supply aside, there is very little that could effect the life of the LED it self. Trust me, I am in no way supporting the government in it's socialist push, I just can't see burning a 60 watt light bulb when I can burn 10 watts for the same output and a much longer bulb life.

A 75W incandescent bulb has an average life of 1,000 hours. 10 of them used in a row will last 10,000 hours. If they cost $0.50, then the total cost is:

10 bulbs x 1,000 hours/bulb x 75W / 1,000W/KW = 750 KWH
750KWH x $0.12/KWH = $90 to operate for 10 expected lifespans
10 x $0.50 = $5.00 to purchase
Total cost = $5 + $90 = $95

If a 75 Watt equivalent LED bulb consuming 11 Watts and costing $24.99 lasts 10,000 hours (1/4 of its rated life expectancy), then its cost is:

1 bulb x 10,000 hours/bulb x 11W / 1,000W/KW = 110 KWH
110KWH x $0.12/KWH = $13.20 to operate for one quarter of its rated lifespan
$24.99 to purchase
Total cost = $24.99 + $13.20 = $38.19

If it lasts, the LED bulb (though ridiculously priced up front at $25 vs. $0.50) is the much better buy for the long haul. The break even point comes at about 3,750 hours of life for the LED bulb, which is less than 10 percent of its 40,000 hour rated life expectancy.

I still haven't seen an LED that looks good. You could give me a lifetime supply and I'd still say they are crap until they can light up a room instead of a spot on the ceiling.

And I can't tell you how many CFL's I've replaced. I have them in my kitchen overhead lights and they might last a year or two.

To be honest tho only real thing I have against CFL bulbs is they aren't supposed to be used in a enclosed light fixture, all of my house lights are boob lights and I dont plan on changing them to accommodate the bulbs.

I'm only posting this because I am so surprised, however this will be my one and only LED.


First shot, LED on Left , 40 watt incandescent on the right.

Next shot LED on right 40 on left.

I put 6 CFLs in a light bar across the top of my bathroom wall...3 of them died in a year. Naturally I did not have the receipt. I was not impressed.

Wow... I have been replacing my incandescent bulbs with CFLs as they die. Been using CFLs for about 3 years. I have only had to replace one out of 10 or so.. Maybe their production isn't consistent...

We have the same arrangement, and we are having the same results.
