Have them on two flags. Come on at dark and last thru dawn most of time. Depends on how much sun they get during day I had to buy 5 and return 3 to get two that worked out of box.

I can not say for certainty and I would not want to lie. I am not awake before dawn. I only know the lights come on at dusk and are shining brightly (a "white" light, not a "warm" light) at 11 pm when I go to bed. I do believe it is important for the solar panel to be located in such a manner to receive as much direct sunlight/charge throughout the day to perform the best at night.

Seems like it will last all night if you have it in full sunlight during the day. Mine gets less than 6 hours during the day and is still on, though it be dim at 4am.

Keep in mind, the U.S. Flag Code does not "suggest" lighting at night, it mandates it. It also only states the brilliance be "sufficient to make it easily recognizable." If the light is bright enough for someone to recognize it as our ensign, it is good. Leonard Jackson, SMC(SW), USN, Ret.

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.

I bought this light to illuminate my American flag on the pole in the front yard. It gives a very bright light, considering it is only a 75 watt but even though it does a great job of making the flag look beautiful at night, the light does spill over onto the house somewhat. It is not a tight spot, yet I would not consider it a flood. It lights the flag and part of the upper house. I have it aimed at the flag from a short side distance so that could make a difference. There is no electricity available right at the flags base so had to do it this way. The bulbs are readily available in Home Depot for a little over $5.00 It would cover a 10' width easily, and a little more. Very bright.

It stays on constantly from dusk to dawn. We are using ours as a flagpole light and it's very bright.

I used it out in the field while hunting, very bright and if constantly on, lasted one full hour. If used off and on, went one week between charges. Hope this helps, great unit and want the next size unit.

Well, after a month but not using it every night...it's still on the original set. Since the lights are LEDs, it should go for a very long time.

The light is suppose to last longer than a month. I know it's suppose to have a year warranty on it. I've seen customers have them last a couple months, maybe up to a year. It just depends.

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.

Also be sure not to twist the end cap too tight or it will not work at all if this happens just loosen it until it turns on other than that its a great light very bright the charge on the batteries will last 2 to 3 weeks until it needs to be recharged depending on use .although i have had mine sitting for 3 months and it still has a charge with occasional use

Takes a while to charge, so i just let it charge at night. But the good is they stay charged for a long time. My husband charged over a week ago. he barley uses them but we went fishing and the light they are used for worked and bright.

I always leave it on charge overnight. Sometimes a little longer, and it seems to be ok. It is a very powerful light, but the instructions say to only turn it on for 30 seconds at a time, I guess it's because the drain is high, and it gets hot. So, for a quick look around, it's great. But not for continuous use.

It still seems to be 100% durable. It comes on every night. It is the light that illuminates my U.S. Flag, so I would clearly know if it wasn't working. I like this light.

The charge does decay. If you charge it over night it could get you out of a pinch during the day.

Yes, they tell you to have it off when you first set it up to get charged. It lights the flag well, but I don't think it would bother stargazing if it was on.

You won't need to leave it charging. I Charged it one time since I got it a month ago, used it at least 10-15 times, and the light is still bright green.

Hello,It takes about 30-45 minutes to charge. A problem I and a couple of people have had is the charger finishing before the standard battery is fully charged. This light appears to be only good for a short trip about 45 minutes on low. Another problem is the mount. You can look at my review under KRB on how I made a mount.
