According to the package 5000 hours. I don't remember when I bought mine, but I use them to light my easel when painting, 8 hours a day and it's still working.

The Chromolux Full Spectrum bulbs will last 3-7 years depending on the average daily use. They are an excellent value and the most beneficial form of lighting.

I've used mine for several hours. I havent timed it but I've been very happy with my purchase. They will also provide a light beep to let you know before they die to plug them in.

Regular batteries (AA I think) and they last a pretty long time. I've had my first set about two years now and maybe have replaced batteries once, maybe twice. Wear them an average of 9 -12 hours a week.

Depends on what kind of batteries you are using. I have two on my light. They seem to last about 2.5 to 3 hours before I need to change them out.

About three hours. I use them in the gym. I had a long workout one day and they pooped out when I was finishing up.

I would say 6 to 8 hours. I usually have them in the vapor through the night while my kids sleep

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

It really depends on how much you use them but I can say that i use them for around 2-3 hours a day and with that frequency they last about a month.

It depends in what do you gonna use them. In a hand lamp about 6 hours without turn it off. But they are the best. :)

Not long, a couple of hours. But I use them at work so I put them in the freezer before I leave for the day so I am not sure on the exactly how long.

I cannot answer that fully. I have not left them on long enough for them to lose charge. I have the manual at home. So I would guestimate 15 hrs? Maybe more, maybe less. Best bet is the manual, what it says, but if you don'g actively correct them for a long period I would think it would hold charge a little longer

Mine has lasted at least a couple of hours. I haven't needed it longer than that.

five to six hours is the best I've gotten from them. If your getting 4.5 hours of use out of them you're doing ok. I've had 2 sets and they both got about 5 to 6 hours of use before I had to plug them in. Bob

They last a normal length of time. Do not recall how many hours. More importantly is that the light is not very strong. Depends what you need them for but they do not illuminate very much.

Less than 4 hours for mine. The battery really does last a long time. I've had mine for several months and use them for up to 4 hours or more at a time, a couple of days a week. I have only had to charge them a couple of times so far. I am impressed with the battery in these.
