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.  "See your sewing in a whole new light".
