I have the Icon puck light, and it's been seeing a lot of use as I swap the suspension, control arms and some other stuff on my wife's Mazda.
The brightest 2100-lumen setting is a lot of light (which is great for these aging eyes) and it supposed to last 2.5 hours, but I generally wind up using the 1000-lumen mode, and it has lasted for a day of work being on a fair bit (rated for 5.5 hours) a couple days. There's also a 280-lumen mode that says it will go 12 hours. I love that it charges with USB-C, and seems to charge relatively quickly.
People will grump about lumen-accuracy, and I have no idea about that, but the medium/1000 mode for the Icon is definitely brighter than the 700-lumen mode on my Milwauke Rover (2367) Service/Repair light.
The Icon is bigger than the Braun light, and more expensive, so some folks might prefer the Braun,
