        A:  If the battery isn't inserted properly it could bend the tabs in the battery holder portion. You may need to check those tabs and re align them. Be sure to align the battery properly when changing batteries.

          Make attic work easy
          This Milwaukee light has revolutionized my attic and crawl space work. Number 1, Milwaukee is a trusted brand and always makes quality products. So it is with this light. I have several head lamps which are hot, and uncomfortable to wear. When I saw this neck light, I was a little apprehensive because I was afraid it would get nasty from neck sweat. Ironically, it doesn't cause you to sweat and it is not uncomfortable when wearing in hot applications. It is comfortable and fits easily around the neck. It is equipped with a Lithium rechargeable battery that can be used in other Milwaukee products in this line. It comes with a battery and a USB charging cable. It is charged with a standard USB-A to USB-C phone charger (included). The battery life lasts a long time, so you will wear out in an attic before the battery does. Charge time is about 2 hours. The light itself boasts 400 lumens and it is bright. There are 2 lights one on each side of the neck. This creates a lot of light for your application. There are 2 settings for the brightness of the light. The lights are on a swivel head which allows you to direct the light where needed. This is far superior to the head lamps because it is hard to keep the head lamp position where you need it to go. The lights swivel up and down. This light is water resistant, dust resistant, and is fall rates at 6 feet. It fits snug around your neck but not tight. I highly recommend!

          Surprisingly Useful!
          I own several high-quality flashlights and headlamps for the home use and for backpacking/camping. I also have several small work lights and one large one. They are all useful and all have some drawbacks. This is the light source I didn’t know that I needed. And, due to a winter rain storm, I have already found it more useful than I expected! Flashlights require one hand to use and headlamps often don’t do a good job of providing light to where you want it for close work. Work lights leave your hands free and can spot a particular area well but also require a solid place to put them and often need to be adjusted while you work. This dual light neckband leaves your hands free, allows you to see a wide area in front of you, and in a lot of circumstances gives you light where you want it without your having to think about it. On a recent stormy night, I needed to access a shed which has combination padlock. Entering the combination is a pain without good light and the padlock is much easier to operate with both hands free. Using the neck light, it was easy to enter the combination, open the lock, and quickly get what I needed from the shed. This neck light has two lights and each can be adjusted upwards or downwards independently. So, it is possible to illuminate a large area vertically. The beams are also relatively wide; so, you will still get a good horizontal illumination. Good to Know: 1. This light is best at illuminating things near your body to about 10ft away. For things like setting up a tent, cooking at a campsite, crawling through a tight crawlspace, etc. this light is a good choice. Light falloff is noticeable after 10 ft and you will probably want a different light source beyond 15 ft. or so. If you need to see a good distance away, a tight beam flashlight or headlamp are probably better choices or use them in addition to this light. 2. The on/off button light has a color coded flashing light which indicates charge levels. 3. This requires a unique Milwaukee battery. I would rather this used standard size and readily available rechargeable batteries. 4. The charging port is on the top side of the unit and the “snap shut” battery compartment opens to the top as well. Both make me wonder how water resistant it will be if exposed to significant rain. Conclusion: This is a surprising useful light! For me, I expect that it will replace both headlamps and flashlights for many uses.

          What a great accessory!
          The Milwaukee 400 Lumens LED REDLITHIUM Rechargeable Neck Light is ideal for illuminating the table work area right in front of you. I have use several lights that mount on your helmet or headband, but this beats all of them hands down. I am a crafter and not that young anymore. So, I need plenty of light. The description says it has two light levels but I would describe them as bright and even brighter. You don't want to shine these on someone's eye! They charge fast and you don't need to buy batteries.

          Amazing light!
          This neck light is amazing! It fits comfortably around my neck and stays put. The unit is really solid and sturdy, and the fit and finish is perfect. It came with a USB-C charging cord, but requires a USB charge adapter for an electrical outlet. When charging, a bright ring around the power button illuminates to indicate the charge status. The lighting is fantastic and can be adjusted between high and middle level brightness. The middle level is bright enough for most purposes and allows the battery to last up to 8 hours. The high brightness is very strong and can run for up to 2.5 hours. Each light can be adjusted up or down, as needed. I’ve had a head-mounted LED light for years. It’s pretty good, but no where near as adjustable and comfortable as this neck light. I highly recommend this product, however it is a bit pricey.

          Excellent pre-charged light source
          Keeping both hands free, this light is a rapid problem solver. The package is easy to open, and it comes pre-charged. Within two minutes, you can have it out of the box, around your neck, turned on, and be at work with no other light source. I used it to finish spending compost on a newly reseeded lawn, and it had plenty of charge to complete the project. I found it to be comfortable around my neck. The two beams of light can be directed Independently, straight ahead, or anywhere between about 90 degrees up and about 90 degrees down. Recharging is easy using a USB-C charger, which are ubiquitous. The charging cord is red, like the device, and the color helps to identify it as the cord for this item. This would make a thoughtful gift, as it can be used for so many tasks, be it walking a dog, bringing in mail, taking out trash, getting firewood, or working in a dark indoor space.

          Works Great! More comfortable than a headlight. Not for extremely close work
          Works Great! More comfortable than a headlight. Not for extremely close work This neck light works well providing general lighting in front of me for jobs that are a foot or farther from my face. For extremely close work, my hands create dark shadows when wearing this necklight so I use a light on my forehead instead. The necklight is quite comfortable. I can easily forget that I am wearing it. It weighs just half a pound and lasts for hours. Then I can either plug in the USB-C cable to recharge the battery inside the neck light, or pop out the discharged battery and pop in a fresh one. [Home Depot carries both extra batteries and an external charger, but I use my necklight as my charger.] The necklight doesn’t move when I turn my head to the side, but its light beam is not so focussed that this is a problem. The neck light provides a wider beam for more general area lightingthan the focussed 600 Lumen Spot beam on their head lamp Milwaukee Model 2116-21 for visibility up to ¼ mile. I can aim one or both LED lights up or down or one up and one down as appropriate. I leave it on the low setting most of the time. When it wakes up it remembers my last setting which is nice. I just hold the button down briefly to tell it to change brightness levels. I much prefer the long press to having to toggle through each brightness setting every time to find the level I want. It is easy to find the control button by feeling for the raised circular switch to change the setting from low to high or high to low, but I have to take it off my neck to check the battery level. The ring around the control button changes color to indicate the level of charge in the battery; however, it is impossible to see while I am wearing it even if I try looking straight down. This necklight is good for both work and play. It is also great for camping. It lights the path just in front of me while I go to the car and leaves my hands free to carry a load of stuff back to our campsite. Overall, this is a well designed, rugged light that just works right so I don’t even have to think about it

          A Fantastic Neck Light from Milwaukee
          This neck light by Milwaukee is the Redlithium 400L is rechargeable and provides 400 lumens and keeps the charge for 8 hours of run-time at the lower lumens of 250. The high run time is 2.5 hours and can be changed by pushing on the power button. The power button always lets you know how much charge is left before recharging with the USB cord. Uses a USB- to USB-C. A connector for charging is not included but we have plenty so it wasn’t a problem for us. The neck light sits comfortably on my neck and is very bright, but not too heavy. The neck light can be used in place of a flashlight for many situations. I can use it for crafts when more light is necessary and my husband can use it for his projects in the garage. The light is moveable up to 130 degrees. A great light to have handy! Lifetime Warranty provided. Made in USA

          An alternative for those using a forehead close work light...
          Milwaukee REDLITHIUM 400L Rechargeable Neck Light, is a novel addition to no hands use lighting for mechanics and hobbyists. I've used for years small forehead lights with an elastic strap. They comes in handy getting light on equipment while working close-up and still have two hands free to hold tools. The neck light serves a similar purpose, and wanted to try because forehead lights aren't always ideal. A forehead light moves with your head, when working, can throw the light off. I found a light on the shoulders around the neck moves less. The light is more stable because your body moves less when working up close. This is a rechargeable light and comes with a provided USB cord that connects to a power source. The light unit as expected, slips around your neck and rests there with two articulated LED lights that move up and down and your body directs it with slight movements left to right. The light source has two brightness settings, high/low and can run for 2 ½ and 8 hours, respectively. It weighs nothing once on the shoulder, comfortable, and importantly, doesn't require keeping your head fixed to point the light. When using it, I quickly forget was wearing it, worked in a more natural way. This is an alternative to other personal lights around and should give it a try, too.

          Amazing High quality neck light
          This neck light is the high quality you expect from Milwaukee products. The two lights rotate 130 degrees and shine very brightly with up to 400 lumens. They run 2.5 hours on high mode. It’s drop resistant up to 6 feet. Rechargeable so you don’t have to hunt for batteries and says you can recharge them up to 2,000 times. On low, it’s 250 lumens and runs up to 8 hours.
