Rated 3 out of 5 by from Does not work with full brim hard hat Overall quality and light output is well but does not fit around full brim hard hats. The band is fully stretched to the max and will lose its elasticity over time. The power cable is also stretched putting to much tension on the entrance/exit points of the battery and light. To help replace the stress is to put the battery off to the side but no longer feels balanced on your head. If you are in the trades not sure if it will work with non full brim hard hats. I’m assuming it will since Milwaukee includes hard hat clips. Do not recommend for full brim hard hats.

Rated 5 out of 5 by from 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.

Rated 3 out of 5 by from 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.

Rated 1 out of 5 by from Lens turning color Exceptional and extremely bright light for a headlamp. I have purchased this headlight for my husband who is constantly repairing machinery. He has had this headlight for approximately a year and is noticing that the interior of the lens is turning a blackish grey, almost like it is being scorched on the inside. Disappointing considering the cost of this headlamp.

Rated 5 out of 5 by from Best light to use when hands are needed Bought this about 6 months ago. A bit hesitant to pay so much for a light. Sold when I made my first entry into a work area where there were no lights. This unit is amazing. The color of the light output is balanced and natural. The weight is comfortable once getting used to it. Mine is worn against the skin with no hardhat. No perceptible heat from lamp or battery. Nice to be able to recharge without spending more on batteries. Over time, the battery is loosing some capacity to charge (minimal), but this is expected with these types of batteries. Overall, I continue to rely on this lamp for working in low light situations.

Rated 1 out of 5 by from Cord from battery to light too short. This will not fit my hard hat correctly. The power cord is too short causing the battery pack to be off center in the back to ensure the light says centered in the front. Had to buy the other 450 lum rechargeable lights. Would love to get one with a longer power cord between the battery and light. Pics to follow.

Rated 5 out of 5 by from Best in the business Like many others, I’d been waiting for a USB rechargeable headlamp from a tool maker, something robust and durable. Milwaukee delivered. I have this model, the previous model, and a flashlight and stick light that use the same battery. They’re all incredible tools. Admittedly, I seldom need a hard hat, so that’s not an issue for me. I can see why those who need this to work with a hard hat would be frustrated. If you need hard hat compatibility, go with the previous model, the one with the battery in the front. Over all, I am beyond satisfied with this product.
