This cordless sewing-machine light will give you 3 levels of brightness and allows the flexible neck to be pointed where it's needed most. It runs for many hours at a time. This brilliantly-lit (but always cool to the touch) LED, light-fixture attaches by velcro; but resides in a cradle for easy USB-C recharging. It's easy to see how much life is left with the green power indicator. The Flex is for sewing situations when you need a better light source. Perfect for older sewing-machines and older eyes.
