            Not sure, I would contact Milwaukee. Sounds like a defective light if the batteries are good.

                  We love this light , it works great and the light from it even on low in a home at night without power is more than sufficient and also with the adjustable surround light, it is great for any situation we have encountered !!!

                    Love my Milwaukee Tools!
                    I have several Milwaukee M-12 tools, and this CP2.0 battery fits them all. I have been using M-12 tools since they first came out, and I have yet to have a battery completely die. I have used them until they were discharged, and then recharged them, but so far, none have completely died. Considering how Lithium batteries are, I'd say that is pretty amazing! The Milwaukee chargers tend to be fairly quick at recharging the batteries too. I love all my Milwaukee tools! Thanks Milwaukee!

                      Outer battery casing is made of very cheap quality
                      The Battery's quality is too cheap. I am a DIYer, which means I don't use my tools for living. Despite not using it so often the battery lasted me only 4 months before the outer plastic casing and inner cells broke apart and it became unusable. The sad thing is all my M12 tools are pretty solid, but the battery is the weakest link. I am so disappointed with my purchase.

                      Hello, this is Elise with Milwaukee Tool. Jag, thank you for your review. We’re sorry to hear that your experience was not of the standard that you expected. We would like the opportunity to explore your feedback further. Please feel free to contact us directly at socialmedia@milwaukeetool.com if you would like further investigation into this matter. We look forward to gaining resolution on this for you. Thank You
                        Very bright
                        This honestly exceeded my expectations. Very bright and well balanced with a 4ah battery. I have a fairly large yard and wanted to be able to see to the woods at the edge of the property, I figured since I already had M12 tools I'd give it a try. I couldn't ask for more. See pics for an idea of what kind of light output you can expect.

                          Nice light with 3 levels of lighting. Also like the adjustment to light only 180 degrees instead of 360 and in you eyes. Like the hock in top of light for hanging abilities and has notch in middle to stabilize light when hanging. The only problem I see with light, is that it won't stand on it's base unless battery is installed. All in all, another quality Milwaukee product.
