    I bought an inexpensive one online a few years ago specifically because of my disappointment with enclosed CFL type bulbs (globes and R20/R30 replacements.) I wanted to be able to quantify and compare a few brands. More engineer toys...

    I agree that some brands may have ballasts that can better handle the increased heat in an inclosed fixture, however I tried two different brands and both failed in a short time in my enclosed fixtures. My solution was to swap out the fixtures for some open ones and I have not had a lamp failure in those locations since. Maybe I should try again. What brand CFLs are you using? Since swapping out the fixtures I have discovered that you can buy CFLs made specifically for enclosed fixtures. However I'd rather not pay the price premium for those bulbs if there is something that works that I can get locally.
    I'm using the EcoSmart/n:Vision/Commercial Electric (all three are the same bulb/model #, with a new name every few years) from the big orange store. They are relatively inexpensive, instant on, and have shorter dimensions than most others which makes them better for retrofits. I use a mix of 40W and 60W equivalents in bathrooms. About the only negative I've noticed is that once in awhile one will have a noisy hum that I can hear and I'll pull that bulb. But that is just a couple out of many dozens.

    I also use some Sylvania micro-mini twists for tight applications like inside some ceiling fan globes. They are about 3x more expensive per bulb, but have worked well where replacing the fixture wasn't an option and I needed to pack the most possible lumens in the tightest space. They are instant on.

    I didn't like the Lowe's store brand CFL's when I tried them, they weren't instant on. I've relegated the one remaining to a closet. I've got little good to say about the GE's--oversized so they don't fit well; not instant on so if you have several in a fixture it looks cheap; short lifetime for a CFL although still several times that of an incandescent.

    I also haven't read much favorable about Feit CFL's so I avoid them. Often when folks are complaining about CFL's I find that they are using Feits, but I haven't used them.

    I think its the short cycling that is killing them in the bathroom. The CFLs in the bathroom last for years (usually) before failing, so I'm not saying they fail right after I install them, but on the same switch I have incandescent bulbs that last just as long or longer.
    Could be, but I haven't noticed any short cycling problems with the CFL's I've used so far. In fact I've noticed more problems with incandescents in that regards. Nearly all incandescent filament failures occurred when I flipped the switch on rather than later in operation. This was particularly true when the bulb was outdoors or in a cold house. With incandescents the thermal cycling seems a likely culprit. The filament is going to have a vapor pressure (however small) and will lose a little mass to be deposited on the glass each time it cycles on/off.

    The one thing I did notice about the GE CFL failures was that they were usually the opposite of short cycling. When the kids were very little we left the hall bathroom lights on for them and/or their closet light at night. We were getting only a few thousand hours out of the CFL's in that service. These were the 60W equivalents as memory serves.

    I've converted two out of three of my AA maglite's to LED's and have been very happy. The conversion kit was about $8. I don't mess with the switch provided for the rear cap in the kit since I had read it was problematic. It's been a great upgrade for camping/etc. since I tired of replacing batteries and bulbs in the maglites. Hated having to swap those tiny bulbs in the cold at night. The maglite bulbs dim as they are failing, and that was an annoyance too. I noticed that the bulbs lasted about twice as long as the batteries, which is pretty poor. I'm pretty sure that this will pay for itself in bulbs alone...while the battery savings are much greater.

    Of course, I've been using dimmable red LED's for astronomy for ~15 years. I still use the original one, bought a second one for my wife. The little 9V that powers them sometimes lasts for years.

    Got to Love them Toys, I can get a good price on them if someone needs a light meter.

    I have noticed that Thunderstorms cause the Filaments to open, Because of vibration, Rough Service bulbs have a more secure Filament holder within the bulb.

    Thanks for all the different input about the different bulbs.

    Now I am thoroughly confused about what are the best.

    But that is a good thing...

    AAAs suck, Go for the AAs. AAAAs cost more than AAs.

    Can You say RIP OFF ?

    The AAAA is used in the Medical devices that the people on Medicare use.

    They are a big waste of money that them folks just don't have.

    I save a big amount of money by staying away from doctors.

    I am not afraid to die, That is part of Life. Screw the Blood suckers...

    I never heard of the AAAA, but I have used N and Z cells. Yes, AAA's suck, but in this LED flashlight, they've lasted years!

    I'm not afraid of falling out of a plane either Don, but its the sudden stop I fear.

    They put 6 of the aaaas in a 9 volt battery , they use them in the blood pressure testers.

    Buy them for the blood pressure testers they are $2.50 each.

    Buy a good 9 Volt battery and you get 6 for $5.00.

    Same Battery, 6 for the price of 2, Go figure...

    Take a 9 Volt battery apart and take a look.

    Make sure you are setting down, When you look...

    last time I dismantled a 9v battery was after I tongue tested it when I was younger, and smashed it to bits after that MF bit me (MF= mighty fine)

    Old school 9V batteries had Hearing aid batteries in them.

    They seem to target us Old folks.

    Guess they think that we have a lot of money.

    Most Old folks did have money, Before paying the Doctor bills...

    I was Kidding: NOT

    maybe a boat payment.
    The doctor bills Medicare 400 bucks, they pay the doctor 68 bucks, my secondary pays the doctor 12 dollars 6 months later, and then the doctor sents me a bill for 9 dollars
