Do these really last 100 hours?

I haven't actually timed them, but I burned one for about 8 hours one night, and couldn't tell that the level had changed much from the unopened ones. I would say they do. Keep in mind, it's a CANDLE! You can't read by it's light, but you can keep from tripping in the dark.

Yes. They last very long too. My daughters bday was over a week ago and she's still playing them =]

There is no guarantee printed on the material. In my experience, they lasted about 12 - 20 hours.

Another spot on Amazon site specifies these are rated to last 70+ hours. Just last week I got a Restoration Hardware catalog and saw LED candles - the cheapest was $19/EA but they specify the candles last as long as 1,000 hours. Had there been better information at Amazon site at the time of purchase I would of not bought these HOWEVER I do have a supply of Eneloop SANYO rechargeable batteries here at the house so will just bite it. Technology has made great leaps in LED lighting in the last couple of years there is much better alternatives.

I've had them a month and have used them for hours at a time and they are still working. I didn't think they were gonna last this long to be honest. They take watch batteries in case you were wondering.

They work good for me. To be honest I don't remember for how long thy are given, but my son uses his computer extensively and after 6 months, still works 4 hours mainly looking at videos on the net.

They are hit or miss. Some last just as long as Duracells, but for the most part, they do last long at all.

I assume so but they should last for years. My mother uses hers 10 to 12 hours a day for nearly two years.

They are designed to last approximately 30-45 days. However, I have seen customers that have gotten much more time out of them. An average usage time would be about 2 months.

No idea... But when they worked, I loved them.... Then they didn't, after about 15 hours of use.

I've had mine about a year, use them every day for at least 3 or 4 hours. Still perfect.

These last as long as the higher priced ones. Being an obsessive record keeper, I can tell you exactly how long they last. I get 7 to 10 days from them, in the summer, and 5 to 7 days in the winter. No clue why there is a difference with the season, unless it is due to heat being on. (I have 2 Siemens hearing aids.)

4 to 5 hours I believe... depends on what your doing with them, constant music shorter battery life...

Yes, you throw them away after one use. That being said, they last for ~12 hours.

Are you asking whether they fade with age, or whether you can put them on a dimmer circuit? They are supposed to last a long time: "50,000 hours". That's almost six years, full time. If you mean on a dimmer circuit, I don't know, and can't easily try. But they may work well. They don't cost much, so give them a try.

Yes, they do last several hours, especially if you have a small insulated bag, or wrap in something insulating like paper towels in a small case. I use a large eye glasses case, or a small make-up container. If the weather is not going to be over 50 degrees, you should be able to get longer than that. You can also request a room refrigerator in your hotel room for a nominal cost.

Don't know, I haven't had to replace them. But it's my understanding they last or thousands of hours.
