How long does the lamp stay lit on a full charge?

After it's fully charged it last awhile. The longest I've had mine on was 1hr 30 mins

It seems to work as the instructions describe, 8 hours on low, 4 hours on high. http://www.dpled.com/en/Proinfo.asp?ProID=2041

I would guess several hours, I didn't keep it in constantly after a charge, but using it 20-50 minutes at a time a few times a week, it lasted over a month for me.

I am not sure about how long it is. I have had this "new" lamp for 4 years now and it's been working great.

I agree with previous answer. Fully charge it when you get it -- it has indicator lights showing when it's fully charged -- can take about 4 hours every time. I use mine in gloves, and if it's on max heat it fully discharges in about 2 hours, but lowering the heat extends it to 4+ hours. I got a spare pair that I keep charged as well.

The battery can be recharged but I don't know how long the charge will last. However, since the light is only on for about 10 seconds I believe it will last for quite some time with moderate traffic (on/off frequency). Furthermore, since the charging panel is detachable so you can place it separately from the lamp, in a location where it perhaps will get some sun light. The panel I have is only getting direct sunlight for about 1 hour per day and this is enough for the battery to stay charged.

According to the User's Guide, in the Normal Power Consumption mode, lamp life is up to about 4,000 hours; in the ECOPower Consumption mode, lamp life is up to about 5000 hours. Lamp life will vary depending upon mode selected, environmental conditions, and usage. Brightness decreases over time.

Don't know how long it lasts if left on for a long time. We use it all the time and it never shows signs of dimming. We let it charge about every six - eight weeks.

I've only used mine twice, with the rechargeable battery, and each time never had a problem with the battery running down in the 4-5 hour period used. The lamp puts out adequate light to see by for walking around and for reading. The high setting is better for reading while the low setting is fine for walking around.

Not sure of the actual run time per charge, but then I have not had it on for more than 6 hours before putting it back on the charger. Light was still burning brightly when I recharged.

With the batteries new and fully charged, it went on the high setting for three hours with almost no dimming. After five hours, it had gone down a little, enough that when you plugged it in it got noticeably brighter, but still way more than a regular headlamp. I left it on during the day to let it drain after that, and found that 12 hours later (so 17 hours total), it was still on - faint, lower than the lowest setting on my camping headlamp, but enough to see by in a dark house. It took somewhere between four and six hours to charge after that.

Mine can last all night long and into dawn if I have them only on motion detector mode. If it is on continuously and is FULLY CHARGED I have had the light stay on for about 6 hours.

I have had it a long time but in fairness I don't use it continuously as I do another lamp in my bed room. It has not failed yet. I'd say it has been at least 6 months. The electrical is the only weak link I am still trying to find a dimmer. It is worth the cost

I'm not sure how long it takes to fully charge; I've left it charging for up to two days and the charging light never shut off. My guess for how long actually it takes to charge is like half a day or something, but that's pure speculation. And to answer the other question: Yes, as long as you're reasonably careful.

About 3 hours is probably the longest I've used the lamp (I use it in my sewing room). I use CFL 120v 14w and don't recall that it got hot.

Yes, very well. I accidentally left my light on for over 8 hours necessitating my first charge. It took less than 4 hours (I was gone for that timeframe) and its back to full charge.

Mine was fully charged and the light was still on. There was no problem with it at all.

I did a test on mine which is about 18 months old. On a full charge, 3 lights illuminated on the side, it lasted 27.5 hours. It was still illuminated but about 1/2 the brightness of a full charge. You can easily get 24 hours of useful light out of this.

Ray, I asked the same question and never got an answer. The first time charged, I let it go for 8 hours and the red light never went out. If I use it for any length of time, I charge it for at least 8 hours. I have it marked on my calender every 4 months to charge the battery and most all the time, it does not need the charge at all. This is the best lantern I ever owned. This is what worked for me. I hope it helps.
