This easy to use, cordless, battery operated light gives you a third hand when cooking outdoors in the evenings. Simply clip it to any cool surface and point the light right where you need to see. It operates on 2 "D" cell batteries. When clamped onto the grill, is it easy to adjust to the desired angle. This light enables the chef to properly judge doneness. It's also excellent for use as an outdoor reading lamp; for accent lighting or as a work light. Puts light where you need it . . . . . safely outdoors. Clamp other places you need a light - auto, basement, attic, under the dining umbrella, camping and R.V.'ers.
