This long tube fluorescent work light uses a single 15 watt fluorescent bulb rated at 7,000 hours of use. This light has two switches. A rocker switch to turn the unit on or off, and a manual starter switch. To turn the light on, turn the on/off switch on, and then depress and hold the manual starter switch for a few seconds until the fluorescent filament heats up. At that point, release the manual starter and the light will come on. To turn the light off, rocker the on/off switch to the off position. For hands-free use, the light has a single plastic hook on the end that rotates 360 degrees as well as a pair of metal hooks that can be rotated all the way around the high impact lamp tube. This unit has a 25 foot 18/2 SJT cord.
