Read in the dark with the Mighty Bright Triple LED Book Light. It features three ultra-white LEDs that spread light evenly. Clip-on to books or magazines or use as a free-standing task light. The sleek and compact design has a telescoping arm for maximum adjustability. Stow the arm away for travel or to tuck into a backpack. Fully collapsed, the unit doubles as a bright flashlight. LED lights never need replacing. Takes three AAA batteries (not included).
