Skywolfeye 2 Sets 4000 Lumen Rechargeable Flashlight with 4Pcs 3.7V 18650 Battery and Charger, Ultra Bright Adjustable Focus Tactical Flash Light Torch, 5 Modes for Camping, Hiking, Outdoor

The lumens are good on this, very bright. It is disappointing they were not able to accomplish this without using a standard battery. Now I have to deal with this unique battery design and hope I don't lose the included charger that works with this battery. If they needed the unique battery to make it work they should have made it internal and used a standard micro-usb charger built into the device.

I was surprised at how bright they were and how long they stay charged. They have the square grid look when zoomed on but quite bright. Doubt it's as many lumen as they claim but i expected that. Great value for money though.

These are my all time most favorite flashlight for all time! My husband bought some fancy high powered ones that get super hot with a ton of batteries but he and my sons always grab these which I bought for ME! So I'm buying more because they are always being used!

I liked the size, the brightness, and the ability to focus the flashlight to a wide view or more intense view of a particular area. I think I have order 6 of these and given two as gifts. A great buy!

Light works great, and both chargers work great also. They work with One or Two batteries charging at a time.

Good thing I have 2 one for parts. I had 1 of the lights fall of my kitchen table and then would start to flicker when I turned it on. I replaced the batteries with fully charged ones and same thing. Honestly you get what you pay for. If they were durable I would like them more. The flashlight was less then 5 minuets old. Another thing is they use a plastic lens instead of glass and the top piece of the flashlight is not on tight so it loosens and the plastic lens falls out. I think these are a big POS. better buy American made product.

Bought these because the “8k lumen” caught my eye.I picked up a 4k Lumen flashlight recently and was quite pleased, so figured I’d see if I could be twice as pleased with this; should have quit while I was ahead.This set comes with 2 lights, 4x rechargeable batteries (2/ flashlight) and 2 AC pluggable chargers. You have everything to gift one if you’d like or to use them for yourself in two different locations.The point though was the light output. I don’t have a light meter to get a real measurement, so I just compared their brightness with another Cree bulb-based flashlight I had handy. I could have compared with the 4k, but the other was closer.The other Cree flashlight uses just a single AA battery, so it’s getting a lot less voltage than these lights... I figured the little guy would be blown away by these flashlights. Uh, no.Now, don’t get me wrong, they ARE bright. Nice white light, but no way 8k.Turned them on and shone on the ceiling. Turned on my other little light and pointed into the middle of the light beam on the ceiling. If they were truly 8k, I would not be see my little light’s beam....I could.It’s a crude test but effective. An 8k light should wash out any and all other lights... in particular just at a 4’ distance from source to surface.... so that’s a fail for 8k.Regarding other attributes, the lights are nice.Machined, blackened (anodized?) aluminum.Pocket clip.Very solid feeling grommeted slide for wide/narrow beam adjustment.Long enough to feel good in the handButNo O rings on any screw point (bulb, batteries) so not waterproof.Unnecessary disassembly points. You can take the front ring off to take out the convex lens, but that exposes the (apparently non-replaceable) bulb, and unless you break (and then can find a replacement for) the lens, this is just another water ingress point. Also extra disassembly point below the battery/pwr button access that appears to be there just as an extension they put in to make the light long enough for the two rechargeable batteries...my best guess.There is also no indicator for battery orientation. Usually the negative goes towards the spring terminal in battery-powered devices, but the spring is inside the flashlight behind the bulb... if you loaded the batteries negative side in to put the negative on the spring, you’d be wrong. They go positive side in first as is normal with most flashlights (which have the spring on the cap) so the spring is just confusing.Overall, they’re nice. It’s two full sets of a fairly bright flashlight. Decent metal build quality, but not 8k lumen output and not waterproof.

They are darn bright, don't seem to drain the batteries very fast and they look to be well made.
