Incredible light
I use this flashlight everyday on the job and I love how it indicates the battery is going low by flashing three times. When this happens I turn the light to the lower brightens level and it will keep working for hours.

Stopped working
I purchased this light less then a year ago and it intermittently stops working. Battery is fully charged. I turn it on once removing from charger and it will work. When I turn it off it won’t turn on again. Battery shows fully charged but it won’t turn on. I have to keep plugging it in and removing it several times before it will turn on. I really like the flashlight when it worked.

Fine product
Definitely one of the better lights as far as quality and durability goes and the light it emits is crisp and allows for good visibility. However, a more focused beam would be nice as sometimes that is needed. The long life of the battery and the fact it is rechargeable is great. Good product.

Great light output. Unreliable functionality.
I am a security officer guarding a Gas and Electric Company. In patrolling the perimeter of several locations, I usually need a strong flashlight to illuminate the area. I bought this flashlight at Home Depot because it had the highest lumens and was also rechargeable. After about a month of use, the flashlight would sporadically not turn on. If I remove the battery and put it back in, it would usually turn on. After having it in my pocket for a few minutes, it would no longer turn back on until I removed and replaced the battery. I finally realized that the zoom function on the light was causing the problem. I used electrical tape to keep the focus to the tight Focus and lo and behold the problem was solved. That is, until today. Now it no longer turns on and I am frustrated with how to rectify the problem.

Super bright
This light is bright as the sun and seems to be super durable. I keep the charger plugged in on the dash of my van and plug it in at the end of the day.
If used all day I could see the run time being a problem though. Bottom line though for the size of this light it is extremely bright.

I have not dropped it or exposed it to water yet.

I've had this right at six months using it to inspect and service fire systems.
Appears the LED is burnt out.

After six months the lithium battery does not charge. I have a $70 useless object.
