Question: What is the run time?
Document: I got this flashlight for backpacking since its waterproof. But after reading the fine print when I got it it only will run for 4 hours* on high. so I mounted on my shotgun instead.
We always run through flashlights very quickly. Usually the batterys go dead and they are usually hard to replace. This is a pretty nice flash light for the money and it comes with a recharger. it's pretty bright and my dad likes it.
This light just surpasses all others. Yes, it turns darkness into daylight. Yes, when it's humid outside, you can use it as a lightsaber. (you can see the beam) Although there is no adjustable focus, I see no need for it since it's basically a spot light with a flood light. I haven't tested this light in the long run but as of right know, (10 min from putting in battery in flashlight and blinded by the light while typing) it's soo awesome.
Excellent visibility with this multi-function light. Consider it for purchase; you will likely really find it worth your time and money.
Gives a strong beam and the rechargeable battery seems to last a long time even if it just sits in the car till needed.
The light would not turn on to bright. Replaced the batteries and allowed it to charge for the required time, but it still did not work properly. Returned with no issues.
I should have given more attention to the negative reviews. Battery would not charge at all rendering the flashlight completely useless. Waste of money and time...
Unfortunately, the flashlight did not work when I received it. I followed directions exactly as far as charging time and battery placement, but it didn't even turn on.
Make darkness and night time become daylight in an instant! This flashlight is compact, lightweight and very useful for anything you might want to see in the darkness.
Here was my initial review:  The actual light beam functions are great. But here is the downfall, each time you turn on the light it switches functions. So at a time when you need the constant beam, it could be doing the strobe.
Answer: yes
