Stay far far away from this light.  5 out ot 6 failed..that;s an 83% failure rate

I ordered 3 of these from the seller RubberDuck.  When I got these and tried the  first one, I thought I had struck gold.

When this products works...which I will discuss later,it is truly an amazing product.

Although in the brightest mode, it can get rather hot.
The rest of the modes, including medium, low, pulse and SOS (yes SOS) are great.

However, then I ordered 3 more.  And when I got those, none would work past the first time I put in the batteries.

They simply flashed one time, and literally quit working.

Then I went back and tried the other two, and they also would not continue to work.

So 5 out of 6 failed to continue to function.  Occasionally, after pushing the button 40-50 times one would work a few minutes
but then it quit.

To be fair, the seller Rubberduck immediately refunded my money, even before I had a chance for UPS to pick them
up with a free return service...so my hat is off to Rubberduck as an honest seller.

JUST DON'T BUY THIS LIGHT...it is junk

Purchased 6 lights. The first failed within a month and the second failed 6 months from purchase. The lights are on for the recommended time -- 3/4 hours per day. The color of the light itself is really pleasing as it's not too yellow. Unfortunately, the rather short life of these LED bulbs makes them not a long term solution. I'll be looking for another brand at this point.

(Update 1/28) -- and now we're at 7 months from purchase and three more have gone out. I've since purchased Philips Soft White LEDs which are maybe another $1-2 more per unit, but I have had zero issues with them so far.

FINAL UPDATE:  Complete JUNK.  Typically people buy two kinds of lights in this category a good one with a good warranty that may cost a bit more but you get reliability and support or they buy a cheap one probably imported that may fail but works and is cheap if it dies no warranty you throw it away and you buy a new one.  This one looks like category one but is category two at best.

If it was 5 or 10 bucks might be a good deal.  Mine seemed nice but it died.  i contacted warranty support and after several days received a response with very basic instructions. i.e. make sure you have new battery, is it tight, clean the threads etc.  responses were very slow takes a few days to get one.  Finally since it was obviously dead they suggested i return it to the seller for warranty support.  Amazon return said it was past the 30 day return period.  They said so sorry you can return it to the manufacturer in HONG KONG no joke.  here is the address they gave me.

Needless to say AVOID.  buy a 4sevens a fenix, anything else but this.  if it breaks you'll regret it.

END:

I'm a big fan of these small bright lights, you can get a bigger light you carry in your pack or car etc but the one you have on you beats the one you have in the car on on the pack but just don't have with you when you need it.  you also find that you will use a light like this all the time.  Put this in your pocket and keep the other one in your pack, car etc.  You might wear this one out before you every have a need to turn the bigger one on.

UPDATE: 1.5mo old and it died.  Seemed really well made.  changing to 1 star, two days with no response from warranty support.  If customer support comes back will edit again.  However at this rate I'll go back to a 4sevens quark and never look back.

Osram is a German company and once would assume they have good products but unfortunately this one is NOT!  I bought 5 of these from two different sources and when I opened my first light, it worked, excellent.  Opened the second one, the LED output was dimmer like at 25% so it is a dud.  I put the second one to use in an area that does not require bright light so it serves the purpose and it is the only one that still working at 25% light output since early Summer.  The 1st, 3rd, 4th and 5th one all DIED within months, some failed within 2 to 4 weeks.  For the price I paid, I do not recommend them at all.  I even emailed Osram/Sylvania and they told me they will send me 5 replacement coupons for all the trouble I had encountered but guess what, I got nothing from them, NOTHING!  So they made a inferior product and the customer service sucked on top of all.  DO NOT BUY this product, the failure ratio is just too high.

I have been through three of these flashlights in less than a years time.  After contacting Maglite, they instructed me to send them the light. Not the answer I was looking for seeing as there was no offer to send me a replacement in the meantime nor was there an offer to pay shipping. All three units came from Fleet Farm in Cambridge, MN as I felt I had no choice but to just continue to return them as they went bad. Out of the package they worked great. This light has a rotating bezel that serves as both the on/off mode and focusing ring. After +/- a month of use, the rotating the bezel would fail to illuminate the lamp and I would have to resort to tapping it in my hands to get it to come on making it complety unreliable. All three units were the same and now it resides in my desk.

The bulb/charging section is the same used by thousands of cheap Chinese night lights. And they rarely work.
We purchased 4, and 3 were dead out of the box. I even put NiMH batteries in them, but no luck. I tried a new and charged set of NiCads in all 3, no luck. Evidently they do little quality control during manufacturing, and Maine (importer) does no QA at all before shipping them to Lowes.
The LEDs are surprisingly low output (for the one unit that worked) - we measured them at less than 2 lumens. A normal AA flashlight produces about 150 lumens. It's barely visible at night. It basically lights up the unit itself, but is much too weak to shed light on anything else. No, it won't help you find the steps. In fact it didn't even light up my hand 1' away.
To make matters worse, they're using 1960s technology Ni-Cads, which will usually only last 5-6 months in the very best of conditions. They could have used NiMH, but that would have cost another .10c per battery - a cost they were not willing to absorb. The newer NiMH batteries last about 30x longer than NiCads, and their shelf life is upwards of 10 years. And they run in extreme cold and hot, unlike NiCads.
An finally the electronics section of this unit is full of hand soldered electrical parts, hand soldered because automated circuit board manufacturing would have produced working units at the increased cost of about .05c/unit. All electronic parts are of horribly sub-par quality with broken wires, loose battery connections, defective charging circuits, and defective/low rated LED bulbs. Again they could have used reliable capacitors and transistors and solar panels, but all told that would have added another .15c to their manufacturing costs.
As an electrical engineer, we took one apart just to see what the issue was. Some parts were actually manufactured in the 1980s, and the capacitors had leaked and rotted - apparently before assembly. The transistors are of a 1978-ish design, and when the "tech" soldered them to the board she broke one of the stems rendering it inoperable from the factory. The solar panel was micro-split in 3 places, and one of the units was never form-finished at all. And it was assembled and shipped to a Lowes store in that condition.
Now I know we owe the Chinese $trillions of dollars, but must we accept this normal sub-par exports from them? Come on Lowes, who's doing your buying over there? Look at the other reviews - most only work for 3 months, and most don't work out of the box (like mine).

Stay away from this light. It is garbage. It stays on all day. You can't shut it off
 Second one..both new..company won't stand behind it. I wish there was a class action lawsuit.

The light was fine.  For just enough time that the return window closed on me. (it closed 3 days ago).  The light just inexplicably stopped working.  I have tried everything to get it to charge and turn on.  Nothing.  In hindsight, I should have sent it back instead of trying to see if I could get it to work.  I would have had two days to send it back but now, I can't.  I WOULD NOT recommend you to purchase this light.  It obviously has a very short working life.

45% failure rate in the first year for all bulbs installed.  Makes for VERY EXPENSIVE light bulbs

Well let just start with, I am an actual customer. 25000 hours? not on your life. At best 250 hour. Maybe they had a key stuck on the keyboard when posting the specs. Do not buy these! You will waste your money buying junk that will ultimately fail, well ahead of life expectancy. I purchased multiples of these to replace cfl's throughout my home. With varying output and design. This NICEYOU 11W A19 E26 100 light bulbs are absolute junk. One failed and ! gave the benefit of the doubt and purchased a replacement. When I should have replaced every one of these because every single one of them are failing. They suck to say the least. I would never purchase from them again. These guys are selling 1%'s at best. I buy so many leds for my home. This is definitely the cream of the crap crop of my LED purchases. You been warned.

The light quality was good.  I purchased a 10 pack.  I installed  8 of the 10 in my kitchen.  After 15 months, 5 of these 8 have failed.  Packaging states average lifespan 50,000 hours.  15 months is 365*1.25*24 hours = 10950 hours.  So if I never turned off the lights, they lasted less than 22% of the estimated lifespan.  The lights were on probably 6 hours a day.  This means lasted less that 365*1.25*6=2375 hours  2375/50000 = 0.0475.  They last less than 4.75% of their advertised lifespan.  Do not buy.

In searching for a LED high output bulb for the back up lights on my 2016 Rubicon, I came across this manufacturer. Given the ratings, very high, I thought I'd give it a try. Everything is as expected and the light out put was excellent as reported by many. However, in less than 6 months of very infrequent use of this vehicle, one of the two LED units failed. I contacted the seller and was advised that is was past the 30 day return period and the 90 day warranty period so I was out of luck.

In the approximately 180 days I've had these LED units in the Jeep, let's just say I drove it once per day (which was not the case), and each day that I drove it, I averaged 10 times of putting the Jeep in reverse turning on the reverse lights and each reverse incident lasted 10 seconds, this would mean these two LED units were turned on for a total of 5 hours. That is 5 hours of run time and one already failed. Not even close to the 100,000 hours these LED units should last. The actual run time is much less as I typically drive this vehicle less than three times per week. So the performance numbers are even worse.

Be advised that many if not all these aftermarket units are NOT up to the durability standards of the OEM manufacturer. Who makes a LED that should not fail in 100,000 hours and yet can't last 6 months of intermittent use?!!! And given the numbers of reported failures here on Amazon, this appears to be a design / manufacturing factor of a low grade product rather than random failures of a quality manufactured product.

I purchased this based on the high rating as well as the higher cost hoping it would have the quality but that is not the case.

I would not recommend this product as the durability is pathetic. It is completely worthless to have a LED light that has high output but lasts just a few hours and fails at the most inopportune time.

Will look into the Phillips LED reverse light unit as that manufacturer has a 12 year warranty compared to this Chinese unit with only a 90 day warranty.

I bought three (3) of these blackout flashlights. Two failed in 2-3 months and the third failed in the fourth month. DO NOT BUY these flashlights if you want it to last longer than a few months. Neither the flashlight part works or the spot light. We had them plugged in the wall outlet all the time, so the battery charge is not an issue. Prior to purchasing, I verified that it was all right to leave them plugged in so that they would come on in the event of a power outage. They were used for nothing else, were not abused and quite frankly, was never taken out of the wall socket. Again, don't waste your money. We have since bought other plug in outage lights that have a stated one year warranty. Seller said it "should" last a year, but was not willing to replace the three I bought that FAILED. DO NOT WASTE YOUR MONEY. DO NOT BUY!!!

I bought 25 of these lights to light a shop all of  them have failed. They worked for 60 to 90 days then 1 by 1 they started a flash like a strobe I had to replace all of them.. WHAT JUNK

One bulb just died after 3 months.  I wrote the date of installation on the base of the bulb.  I recommend the same to see if the claims RE the LED lights lives up to the hype.  Perhaps the LE company is one to steer away from. I'm sure any item of this sort can have an occasional defect, but we shall see how the other bulbs hold up.  Have not tested their 3yr warranty yet.  UPDATE:  2ND BULB FAILED AFTER 3MONTHS 4DAYS... THINK I WILL STAY AWAY FROM THIS BRAND.

At the time of writing this review there is a 40% failure rate. Of the 10 bulbs that were in the package, 4 died within weeks of being installed. 4 are installed, and 2 are still in the package. I will never buy LE lighting products again.
