Our Super LED Light Sticks are 8" long by 3/4" in diameter. They have an attached cord. They use easily replaceable batteries (3 X AG13 included), and create striking visual effects from three modes: Steady on, Blink, and strobe. Each LED Light Stick will run approximately ten hours on one battery set.
Photos below, while not of our white color stick, are representational of the two flashing effects.
