We have not found a more comfortable illuminated baton yet. Conduct-O-Lite has made this excellent tool for conducting in dark pits, etc. Approx. 10" long with the illuminated end measuring 4". Color: white with black accents. Turn knob at the bottom clockwise and counter clockwise to turn on and off. Light emitted is white. 2 AAA batteries included. New batteries have tested to last for 2 hours continuously.
