Question: How does the seller get-off saying this is a 1600 lumen light, when it only uses a 1000 lumen LED module, AND it doesn't even use 10W?
Document: The flashlight is not even close to 1600 Lumen. I have a 630 lumen Stinger LED HL and it's brighter that this. It came without instructions so you have to figure everything out on your own. The 1000 Lumen  flashlight they have seems to be brighter and better than this one. A nice feature is that it's zoomable, for a pinpoint or broad beam and comes with a 3-AAA battery adapter for regular batteries or you can use the 2-CR123 or rechargeable sticks.
The flashlight was made with precision and quality. It's bright enough to light my way through a path that was pitch dark. I'm not so picky about whether it's 1600 lumens or not, but I have another 1000 lumen cree flashlight and they have about the same output. Anyways, my review is not really about the flashlight, but about the seller Meca. The charger that was sent to me was not the same one that was displayed in the picture.
TRUST THE 1 START REVIEWS. Do not think that you will some how get lucky and get a good one. The seller claims 2 things that are just not true. 1st. they claim it's 1600 lumen. My @$$. My costco cheap 300 lumen flash lights blow this thing out of the water. 2nd and most important to me is that they claim to have a run time of 2-3hrs. Not even close.
This allows it to work again. The button is one that reacts to a light touch to switch modes and also to press all the way down to turn on or off without selecting another mode.So point is search Amazon for Ultrafire 1600 which i see brings up the same exact flashlight for HALF of what it is selling for here.. and also there are some versions that come with the rechargeable batteries. I would get that instead it is 12watts and probably uses the LED to its full potential.
Not even close to being 1600 lumens. Not even 1000 lumens, not even 600 lumens. False advertising. Bezel rattles. Very surprised that its not even close to being what the description says. I could say you pay for what you get, but even though this was very inexpensive I've bought many cheap lights that were at close to advertised specs.
The old saying you get what you pay for holds true. After less than 2 dozen uses the switch fell apart.
I experienced no problems with either. If you don't use an 18650 battery with this, it will be even dimmer. I have 18650s I salvaged from a laptop battery and attached protection circuits to, and I'm quite happy with the brightness. I'd probably only use AAAs if I were using it as an indoor flashlight as that would still light up a room very well in the dark.The advertised brightness is an outright lie. There's no confusion about that at all. 1600 lumens is genuinely impossible with this LED.
Despite the fact that my 4 units took 35 days to arrive from China with no way to track them, these units are highly overrated. They are not even close to 1600 LM Lumens. I have a 500 lumen Walmart brand flashlight that is 3 times brighter than these units. While the zoom feature is nice, when you zoom in to a tight beam you can actually see the LED silhouette on the wall and it is square????
The good: Well made. Neat idea for the focus.The BAD: NOWHERE near the advertised 1600 lumens. I would say it would be a MAXIMUM 400 lumens! The focus works well but when fully adjusted to the spot setting the LED can be seen as it were in a projector.I'll be retuning this even though I have to pay for the shipping.You know what list of mine NowAdvisor will be on.NowAdvisor1600LM Lumen Zoomable CREE XML XM-L T6 LED Flashlight Torch
I don't own this light but it is clear that it is crap! No light in the world produces 1600 lumen from 1 battery! If you want a quality tacticle flashlight that is properly spec'd and works every time and is incredibly bright AND runs off AA bateries.... buy the Fenix LD41. It is now upgraded to 680 lumen and the number is correct. This light is an absolute tourch and projects a beam >220yds. It will literally light up your backyard!
