How long does 'glow-in-the-dark' feature last before it 'burns out' and won't ever glow again?

I put mine in strips on the stairs so the kids wouldn't trip when coming down at night. The stairwell is pretty dim during the day, but the strips still seem to glow bright enough through the night. If it's still dark-ish when I go up to wake them for school, I can still see the faint green glow. I'm happy with them.

The average LED light lasts between 25,000-50,000 hours. In figuring this, if you use the lamp for an hour a day, every day, the bulbs will last over 68 years. There is also a 1 year warranty that comes with the lamp. If you would like to email the company, the address is: info@spheregadget.com and a representative will contact you within24 hours, according to the site. PS...I Love mine!!

I can't tell you exactly since I usually keep it on for no more than 4 hours at a time, then I will recharge it. I've had it on for 4 hours straight at the high setting without it dimming at all. I suspect I could get at least 6 hours at the lowest setting.

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.

You are right. It does not glow no matter how much is sprayed on. I will never buy it again.

I have left it on for extended periods but have never timed it. It is guaranteed to work for 3 years at above above normal use (9 hours a day for three years) with no change in lights or battery. It has a dimmable dial switch that allows for every level of brightness between off and ultra bright.

If it's a tritium sight you should be able to see it in the dark. That' why their called"night sights". They may be old. The radioactive element lasts about 10 years and .may be dead. I would send them back

Nah, I'm front ct and have had my light out at night in the single digits and teens and had no problem. Just keep it in my jacket pocket until I need it and pull it out and use it for about 30 min or so each time and it worked np. Probably used it in these Temps about half a dozen times this winter.

I've had mine two years. Ovevthe past 6 months, I've taken to leaving it on all day (on the weekends when I'm home). I use it like a regular lamp. No problems.May not want to use it as a reading lamp during the evening in the case it keeps one awake.

If they are given a good half hour charge before the lights are turned out, they glow for very long time. Upwards of an hour and a half to two hours.

I've seen a notable drop in the effectiveness after a year and a half. Even though the bulb still glows, it wears out, producing less UV. I suspected recommended 1 year swap out is based on the the bulb is guaranteed to be still effective (producing enough UV) for a year... after that it'll drop off and become useless despite even it still light up.

Sorry for the late response. The on button glows, which is a little star. It wouldn't really be enough light to see it in the dark though.

Due to the way I was using the lights, I turned one on at 6:00 pm and at 9:30 pm it was still shining. It wasn't as bright as at first, but was still bright enough. They are NOT a one time use. My 'test' light still shines when I turn it on. They have batteries and an on/off switch. I don't see a way to access the batteries for replacement without breaking the casing, so once the batteries are dead, then the light is disposable.

No, I have the lights on whenever I use it and it's lasted for 10-12 hours every time

I had mine up for about a month before it started to flicker and dim. I put up with it working sometimes and finally went to lowes and bought one that works all the time.

I haven't had that issue with mine either. I use mine mainly for edging which puts a greater strain on the battery. My battery will normally last between 30 and 45 minutes and all lights go out. I would definitely call their customer service and ask about it.

Not sure if it burns out, I haven't had it long enough. I will say that the batteries last for about 50 hours, at which point the light begins to really dim. Changed the batteries and it's working great again.
