Does this light drop to 25% after 5 minutes of continuous use? I want to use as a bike light.

I've been using mine for about 3 months now, about 40, 5 sec. uses per night at high power. I've had no problems with the switch, and I've not noticed a decrease in brightness over that time (in reply to the question of whether it drains the batteries while off or not; I've never had it on for 5 min. at a time). I love this flashlight.

I've experienced no problems whatsoever with this light. No light drop off after 5 mins.or battery drain with the light off. Batteries appear to last about 6-8 hours continuous use on high beam. My light begins to fade just as the batteries are nearly exhausted, as you would expect. The light beam while brilliant has a short range, no doubt the cars would see you, but a bike light may work better for you.

I found it dropped from high beam to low beam immediately, within a second or two of turning it on. This started after I had it a few days and tested it for an hour or so each night. I consider it to be defective. I bought two, they both had the same problem. I would not use it for my bike. I'd get a special bike light. In some states a special bike light is best, due to laws regarding size, intensity, and color of bike lights.

I have not experienced any drop-off after 5 min. but I did experience far more important problems. The light drains the batteries while off! Do not buy this product, great brand but really a grat fail as well!

I did a discharge test and it went for ~ 4 hours before the light intensity started to drop. After 5 hours the intensity dropped faster but even after 7.5 hours it was still putting out useable light. I'd post a photo of the discharge plot but I can't see how to do it for this product.

Dear jenny paul - I have read the other reviewer, but to be honest - our sensor went off after 5 feet. I guess it depends on were you place the lamp, but still in all, it is bright and working great for us. Hope this helps!

I had the same experience. It operated great for a couple of weeks. Then one day I noticed it was on in total day light. It eventually went out and operated fine that night. A couple of days later it just stopped operating completely. I just returned it for a refund. It's a great light, just what I wanted, and worked fine then just quit. Go figure????

Hi Kan, I used it during two wreck dives (plane and boat) 45 minutes each time. It did not die or anything. In fact I took the batteries out for cleaning and then put them back and they still run. This will run for about 3-4 hours with no break. It's a great light for the price, just don't drop it!Michel

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.

I just want to add onto what Energy Guy said. Yes. Flipping the switch for 3 seconds will leave the light on. The only interesting thing is, when you wait 3 seconds and flip the switch again the light comes back on even without motion. I thought I was going to have to wait till the morning till it reset itself, but, after about 5 minutes of a constant on, it reset back to motion.

not sure about the exact amount of time. I bike from NJ to NYC it takes about an hour and ten minutes and I have used the light on high beam mode for that period time without any signs of low battery. I considered to be pretty reliable.

I bought mine a couple months ago and the light worked for a couple of hours then never again. It was an electrical issue, not a bulb issue. I wouldn't recommend it....

I just looked at mine and yes it is burned out. Thx for bringing it to my attenchion. I'll have to keep an eye on it. I have had this light for about 4 or 5 months now and l don't know when it went out. At this point I have had it on for 18hrs a day since I got it. Everything els is running fine.

I have used this light for diving and usually get closer to 1 hour of use per set of batteries. I usually change them better dives. When they Hey low the light does not dim. It will just shut off.

I work ten hour shifts and have yet to have had a need to run the light for longer than 15minutes. Additionally, I will toggle with the buttons and switch from one setting to the next and so on. I even play around with the strobe light function. I have not used it for longer than 15minutes at any single given time. Just to be on the safe side I always have the second battery in my cruiser. And I charge the battery every night when I go home. Hopefully this helps!

Im not 100 percent sure but ive left my lights on over night by accident and it didn't kill my battery. But every bike is different.

When I left the light on, after about 3 minutes it would turn to a lower brightness then and not go back to the 1600 Lumens. Therefore, I returned the light. I have another Maelstrom flashlight that is very good, but the MMUx3 had problems. Therefore, I bought the Eagtac MX25L3C 3500 Lumens. I have been buying flashlights for a while, but after this beast, I have rested the wallet. Good Luck.

I always gave mine a few seconds rest every minute; that said, I would say yes. That would be at its most powerful setting; I never bothered with the lighter settings. Hope that helps! :)

I ran mine for 2.5 hrs on the brightest mode, just to see what it can do. Didn't see any drop in intensity and still had battery left. How much don't know. My other lights are over $200.00 each so was real impressed with how long it lasted so far.

Unable to answer this question due to only occasional use of this lantern. So far I have not had to use this lantern for a long continuous period of time.
