Nifty little clamp-on LED lite featuring a bulb which pivots from straight ahead to straight down.
The bulb lasts darn near forever and the battery is good for up to 8 hours of continuous use--more for intermittent usage.
It comes with a battery and we throw in 2 extra at no charge.
The last time we checked, these were $2.97 at a "Big Box" store.
Wear it on your cap or lapel. It is the only lite which shines directly down--so you can see even with bifocals.
