Life Mounts Tactical Rail Mount Flashlight - 3.5 in x 1.5 in, White LED - 1,000-Foot Beam & Multi-Mode Helmet Flashlight - 360-Degree Side Mount Helmet Lights - Weatherproof Design for Tactical Gear

Really well made and intuitive flashlight design. Super easy to mount on any arc rail and the flashlight itself is able to be dismounted from the mount within seconds should you need it freehand. The construction is sturdy and thick enough to handle a couple falls though I feel like the mount has some weak spots like the pivoting mechanism which doesnt feel too sturdy. That being said, the mount DOES have a pivoting feature so you can adjust the light to whatever angle you want it to shine on from your helmet which I found super handy. As for the light itself, it is definitely bright enough for indoor/cqb use. I have not tested it outside so I cannot say how far it is able to project. The flashlight does have a focused beam mode and a floodlight mode that can be switched back and forth simply by moving the head of the light forward or backward, useful if you need focused light or just a lot of it All in all, this is a fantastic tactical helmet light for all airsofters or cosplayers ESPECIALLY for the value you are paying for, it is absolutely a steal when comparing to other tactical lights. Military or LE may find use for it as well but I am neither so I'll let the professionals decide for themselves on this one.

Decent little flashlight for my ballistic ACH helmet. Has 3 modes, bright, less bright and strobe. Also the diameter of the light coverage can be adjusted easily. Works great for my purposes

The light started doing that cheap flashligh flicker after i started using it. The mount works good though on my cheap little camo helmet with a nvg10.

The only light that is bright enough to walk my dog at night and still be able to have a free hand. This is a tactical light like the military uses on their helmets. It is very durable and only uses an AA battery. I have both the version made for a dog leash and this one bought as a spare after several years. I bought this one when the one made for a dog leash wasn't available. It can be mounted onto a dog leash with a piece of velcro.

works as advertised with zoom able light control. it uses a single AA battery and mounts on my helmet rails just fine

Amazing value for the price, fits snug on my arc rails without any wobble and feels very sturdy and well built

Holds a charge, but needs more lumens.

Nice and bright for about 15 minutes. Then gets dimmer and dimmer. Can’t even walk one mile with it. It goes out before I get zero light! Another piece of junk!
