I plan to put it by my bedside because I can't sleep in total darkness. How long would it last?

They will last all night and probably 2 to 3 nights. They are powered by three 1.5 volt lithium batteries and can get pricey. However, they are nice and soothing. They contiuously change colors

If you turn it off when your not using it you will get a lot of life out of the battery.

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.

It lasts almost 10 hours continuously, I put it on before bed and when I wake up it's still going.

Hello FP,it would last up to 4 Hours depending the brightness you use on the screen

A long time. I've left mine on overnight by mistake and it was still delivering some useful light.

it lasts approx. 5 hours. that's why i bought more of them to put around. when the power goes out at night it helps to find your way around the house right away, then i just keep a few in where i need them so i can swap out if i still need light longer. the 3 leds in the front are very bright to light stairs & hallways, i like this model the best of the ones that i have. started looking into a back up power supply and/or a solar generator but didn't buy any yet but it would be good to recharge power for an extended outage.

Find the answer here: http://www.medelert.net/ . They say it is about 30 minutes. It would be better if the light were not recessed, but protruded with a very bright LED and a lens that allowed it to shine in all directions.

That depends on the setting. I've never had it on long enough to go out. I usually use it on the brightest setting and have had it last >90 min without dimming. I believe the manufacturer states that it can last 2 hours on that setting. Lower settings will obviously last longer.

Caution is always the best route to take. I have left the lamp on for 8+ hours I cannot advise on leaving it on 24/7. You may consider a light sensitive night light for 24/7 use.

At least 1.5 hours on high, but over 2.5 on low. This light is blinding even on low. I glued some diffuser film to the face of the frame with instant glue to remove the mild hot (bright) spots. It turns night into day. Buy the second battery if you are going long. Warning -This light (LEDs) just shut off without warning when the battery is discharged. Usually at the worst time.

Since this light uses an LED bulb you can expect 5 hours out of the 4 AA batteries it takes to power it. The bulb itself will give you 100,000 hours or about 10 years of use out of it just keep enough batteries on hand and you'll be fine

Leaving it on continuously in a light-use situation, I doubt I was able to get it more than 4 hours.

It will last as long as anything else there is out there, and it's as bright as anything else there is. Having said that the brightness is best at first and then it fades over time but this type lasts with at least some glow for hours. It's not the same as a light but it's paint, so at least there is some slight glow after quite a while. If you want it to continue being pretty bright then you will have to recharge it often with a bright flashlight or the sun etc.

It lasts 4-5 hrs on medium power, its a very bright lite, I like it. If you babysit the power button it could go longer.

I have mine plugged into an electrical socket all the time. I bought it for when there is a power failure at night. When the house power goes off, the flashlight will turn on. Not only will I be able to find it, but I will have light on high for around 2 hours and if I keep it on night lite setting it can last up to 15 hours.For $7.99 it is a great device for safety when emergencies happen. I am not sure how long it takes to charge from the dead state as I have always kept it plugged in since I received it.

you can probably use a timer with this lamp. i keep mine on all day with a low-wattage nightlight bulb in it (7w) to keep a little light in the front foyer of my house all day. turn it off when i get home, then turn it on again before bed to keep a little light by staircase to illuminate steps. depending on the size wattage bulb you use, it illuminates enough light to serve its purpose. i use mine not as lamp to be visible from the outside (it's in a corner table in my front foyer by my front door) to be used as a low light just enough to illuminate the area for which it serves. but you can use a larger wattage bulb to produce more light. mind you, the lamp is small (see dimensions w/ ad) so it would never light up an entire room. they make this lamp in larger sizes as well. it is a beautiful, well-made lamp. the glass globe is beautiful. this was an excellent purchase for my needs and well-priced. i am sure you will not be disappointed. good luck!

They will last through the night but only one (or maybe two) nights. The battery would quickly be extinguished and you would probably spend a lot on replacing the battery every other night. I also use a nightlight but I use a small light that plugs into the wall with a nightlight bulb in it. I also have one of these GE Metal Shade With Flower Design Incandescent Night Light 51386 which works really well. Hope that helps! These Mushroom lights are still fun and are really good for a few hours a night!
