This light is not worth the money in my opinion. It is bright but with no focal point, it is not good for distances. I always recommend Milwaukee, but not this light.

Outstanding!
After I purchased the 2111-21 model I didn’t think Milwaukee could top off such a great, rechargeable headlamp, but they did with this one. Only had it for a day and I love it. Not the biggest fan of the the huge battery I have to carry on the back of my head, but for that many lumens/brightness I can live with it. Plus the front part is so slim and small, it makes up for it. You did it again Milwaukee.

    Does not work on full brim hardhat
    I bought this light and tried mounting it on my full brim hard hat but the head band would not stretch enough and the wire harness from the battery pack to the light was too short. I bought a Milwaukee full brim hat hoping it would work better but it also didn’t work properly. I had to modify the light to make it mount on the hardhat.

      I've been wanting a headlamp for a long time. This one works like a charm. I do not use it with a hard hat since I do not have to work in a dangerous site or anything like that. The headlamp stays on my head really well; not feeling loose and such. The battery on the back also helps to balance the lamp quite well. It's heavier than the lamp itself, but I don't feel any pulling forward/backward. There are 4 brightness levels; the dimmest is usable and the brightest level can blind me if I look at it directly. It's brighter than my 100 watt equivalent LED light bulb.

      Works fine without a hardhat. The only problem will be hiding it from your "friends" that want to "borrow" it! Rechargeable using a micro-USB connector, and comes with a very heavy duty looking USB cable for charging. The head lamp has clips to attach it to a hard hat, but it also works fine without the clips directly on your head. I used it on my head (no hardhat) without the clips. The top strap is removable if you don't want to use it. The battery is in the "lump" at the rear of the light. The light can change tilt so you can adjust it to be pointing down or straight ahead. It does not change focus. The run time is pretty amazing - supposedly 25 hours on the lowest (eco) setting. Down to 2 hours on the very bright (600 lumen) setting. I think the feature I liked best is that it has a separate on-off switch and a hi-med-med low-low switch, so you don't have to cycle through all the choices like many of these things do (and then I always miss the setting I want!).

      The MILWAUKEE 600 LUMENS LED USB RECHARGEABLE LOW-PROFILE HARD HAT HEADLAMP is a terrific product that solves the battery issue once and for all! I LOVE the idea that this is USB RECHARGEABLE which ELIMINATES the need for batteries and one charge will last a long time. I actually keep this near my nightstand because the power goes out on a regular basis and I love knowing that the headlamp is ready to roll at a moment's notice. The different light settings and the adjustable strap means you can use this headlamp WITHOUT a hard hat which is another plus.

      I have been a builder remodeler for 49 years, and as such I have many opportunities to use a tool like this MILWAUKEE 600 LUMENS LED USB RECHARGEABLE LOW-PROFILE HARD HAT HEADLAMP, BLACKS. Anyone in the trades using a hard hat, or even in need of a headlamp, will find that this headlamp works very well, providing high illumination of their work. Also, no batteries to replace, it’s rechargeable!

      This is one of the best rechargeable headlamps out there. It is very bright and the battery really does last a long time. The light has 4 different brightness levels. The only negative is that I can't get it to mount to my bike helmet. I received this MILWAUKEE 600 LUMENS LED USB RECHARGEABLE LOW-PROFILE HARD HAT HEADLAMP, BLACKS for free to write this review.

      The MILWAUKEE 600 LUMENS LED USB RECHARGABLE LOW-PROFILE HARD HAT HEADLAMP works very well. The light has 4 settings from 25 lumens to 600 LUMENS. With run times of 2 hrs to 25 hrs. The headlamp comes with a charger cord and 4 hard hat clips included in the package. The light has a wide flood pattern so it lights up the area very well. Very nice light.

      This is a review of the Milwaukee 600 Lumens LED USB Rechargeable Low-Profile Hard Hat Headlamp. I really like this lamp so far. I have the older model from Milwaukee and the two lights are really different. What I like better about this one is that it is a little more comfortable to wear with the battery in the back. The weight of the other one wasn't awful, but it was noticeable, and this one I don't feel at all. I also like less modes in the new one. The new unit has four levels of brightness, and it remembers which one it was set at after you turn the light off. Really nice. It probably only needs two modes, since the lowest two settings are really dim. It illuminates a really nice angle of about 140 degrees. On full brightness you can clearly see over 20 feet away. The only thing I don't care for on the light, is that the power button is really tiny. Good luck turning that on while wearing gloves.
