I use a similar one that HF sells. It is a Braun rechargeable. I keep one on the Mill and one in the house. I've tried many other types and styles including ones that you wear like a head band and this one work best for me. I have 3 4 foot Led shop lights hanging above my 2 lathes and Mill and as good as they are I seem to never have enough light in the right place. My pocket magnifiers all have LEDs built into them. Can you tell I am an old guy? LOL I have gave several to friends and family members. https://www.harborfreight.com/390-lumen-led-rechargeable-magnetic-slim-bar-work-light-56329.htmlI think I've purchased five of these at this point: https://www.amazon.com/gp/product/B0877794DG
No cord, long battery life, very bright, magnet strong enough to actually be usable. I don't know what I'd do without them. BrightEST? Who knows? I haven't tried them all...
