First off, I really wanted to like this light. The idea seemed really cool - a super bright light for your helmet that was easily detachable and could be used as a hand light. Awesome.

However, there are some major draw backs to this light. First off, it's huge. It covers an entire side of your helmet. If you have a leather with any kind of upward bend, it's going to be difficult, if not impossible to mount. The size makes mounting difficult, ruins the aesthetics of your helmet, and is also an entanglement hazard.

The biggest drawback though is that the light doesn't sit very securely in it's mount. Even a light forward shake of the helmet causes the light to fall out of the mount. If anything were to bump the light from behind, the light would fall out of the mount. The light could easily get separated from the mount during a house fire and you may never find it again.

I returned this and got the streamlight version which is more than half the size and stays securely on your helmet.

Used it at a couple of fires now and it is very bright I mean very very bright it's nice it mounts great to my Karnes 880 helmet and keeps my profile low and lasts for 3 to 4 hours as advertised my only problem with it is my friend got one from a dealer here in town and even though both our packages are identical his light seems a little brighter I thought it may have been a bulb difference (like in reference to color temperature) his is slightly bluer than mine which makes me question whether or not I really have a Cree LED and ended up with a knock-off??? If you're buying this for fire service you'll definitely want to look at the rechargeable batteries with the chargers here on Amazon you can pick a decent set up for 20 to 30 bucks and it's really nice to swap them out every tour or after each big fire or event. If you want to buy the non rechargeables they're $30 for a set at the grocery store here so that's why went with the rechargeables

This setup is awful. First of all it’s huge, and very heavy for a helmet mounted light. With mount and batteries it’s a little over 10oz. That’s a half of a 20oz soda hanging on one side of your helmet!

The worst part about this setup is the slidelock clamp. Although it keeps the light from falling out, it allows the light to freely spin and there’s so much play and wiggle room that it rattles around and makes an irritating noise. Also only attaches to the helmet with 2 finger tight screws.

At this price you’d think the light comes with batteries, right? Wrong. That will be an additional purchase.

If you’re going to go for this type of setup, you could buy the same sized Fenix TK20 light, that comes with a battery, is USB rechargeable, and offers 1000 lumens as opposed to the 200 this one offers, and then a separate blackjack mount for the helmet for about the same price.

This was my 2nd, and definitely last FoxFury product

I really want to like this light setup. The biggest and most serious drawback is the mount. You are limited to only certain spots to mount the light, and on top of that if you have a face shield on your helmet you can forget using this thing. Would've really like to see a mount that I can move to the top and the bottom of the helmet freely in a quick situation like some of the other less expensive mounting options out there. The fact this this is a fixed mount isn't bad, but seriously limiting to those who have face shields on their helmets since you cant mount it where you really want it.

Oh and did I mention, if you wear glasses and you got the light on.... that crap will glare off your glasses right back into your eyes at 200 lumens if mounted too far back....

Hoping someday the mounting for this series of lights gets better, but I will be returning this, as I simply can't use this properly with a face shield on.

I've only used this item for several weeks and it has already started to develop problems. The light flickers and dims with the slightest of jarring, usually when I remove/insert it into the holster, which is quite frequently. Everything else about the light is fantastic, this issue being the sole exception.

I would like for FoxFury to reach out and replace this item, if possible, and I will update my review.

Update: It appears some dirt/grease/whatever was on the positive contact (the one closest to the lamp inside the flashlight). I cleaned it off with a technician's screwdriver and it appears to have alleviated the problem. Updated to 5 stars.

I haven't had this light very long and haven't had the opportunity to use it much. What I can say is that it is well made and bright. I'll update the review after some good hard use. I'm using it as a helmet light for firefighting. Several other firefighters at my department are using the same light and I thought I would give it a try. I also like that it can be taken out of the mounting bracket very easily to use as a hand held vs. helmet light, making it versatile in that aspect.

Good luck finding batteries for this flashlight. They do not come with, and ordering them through Amazon has been weeks and I still don’t have them. There are as good units out there that don’t use such obscure batteries.

So far so good. I haven't used this light in a building fire yet but have been next to a large semi-trailer fire at night. It was super bright and had no issues. I like the green flashing light on the back of the light to let those behind me know where I am. Removes out of the mount easily with one hand to use as a handheld light as well. I still have the original batteries that were included but I also ordered "TangsFire® 4pcs 18650 3600 mAh 3.7V Li-ion Rechargeable Battery + 1pcs charger", which seem to work great in it as well. Much cheaper than replacing the CR123 batteries.
