How long should I change the light?

I charge mine overnight about once every 6 months. Never had a problem doing that. It's an 'emergency' light that gets used to illuminate dark closets, garage projects, or use when the lights to out (i.e. rarely). Doing this charge cycle has (in my opinion) never damaged the battery and the light is always bright and lasts a long time when I need it.

We have had our light for 1 year. We don't use it very often and have only charged it twice since we have had it and it has never gone dim but when we did we charged it overnight.

Real easy. YouTube how to change those head lights. That's what I did. Took about 5 min each. No joke. Easy stuff

We live in he mid-west I remove the lights (we have 5) for the winter and replace them with pvc caps. Change them in the spring.

The batteries are already in the light. Just place the light where it will get direct sunlight for 3 - 4 days, after which you can turn on the light in the proper mode that suits you. These lights need at least 10 hrs of sunlight a day.

It varies, as you can set it for how long you want the light to be on. Not sure what the longest time is, but ours is at 3 minutes and it is no problem at all. We love this light.

yes! i just replaced two in my garage after a period of dealing with 48" fluorescents that came on slowly or not at all until some time in the wee hours of the night. The replacemrnt procedure is very simple and should take no more than 10-15 min. per unit

When the lights comes on to change it, you can simply clean out the filters yourself then reset the light. When the filters get too bad or if you don't want to deal with all that, you can change them but they are expensive. I change about 6-9 months or when the filter is really bad.

the light can be set to stay on for up to 15 minutes when activated by motion. I have had mine over a year and have not had to change the bulb yet. I expect it to last several years.

It's a little button battery. I didnt use it/paid it no mind.Put on your calendar to change after 6 months (or maybe 8 months for one person and two cats?)If your light is lit, just remove the button battery.

You will need a UV light or an LED light I recomend the LED light it's quicker LED light is only 20 seconds

Depends how long you leave it on. If you leave it on all night, probably a couple of weeks. It gets dimmer as the batteries die.

Seems to be about 3-4 hrs. It depends on how bright you run the screen and what you are doing.

Usually new bulbs have a total of 900 hrs but by the time they reach 800 they have lost a lot of life ... I change mine every 800 so it depends on your preference !

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

Actually, I don't think you can replace the bulbs. LEDs are usually good for about 25,000 hours. That's about 20 years.What did you have in mind.I don't know about you but I'll be ready for a new technology magnifying glass way before that.Batteries will be your issue depending on how much you use it not the LEDs.You need a really small Phillips screwdriver to replace them and it takes three. The cover is real bitch to get off. You need a really small Flathead screwdriver to pry it off. Thank God the screw is held in place in the cover or you would probably loos it.A small screwdriver set & a couple of rounds of changing batteries and it's no big deal.

It's a motion detector light, so I don't see why it should stay on for 2 hours. Mine is set for 10 minutes, or so. I've had mine for a year or two, and haven't yet replaced the bulb.
