Work lights are used for a wide variety of applications from illuminating small work places to large job sites. A series of such lights can be arranged to facilitate technicians at work. They vary in the type of illumination source they use - LEDs, fluorescent lights, halogen lights etc. Typically, these lights can work for long hours and have different setting options that can vary light intensity. Sometimes dual mode power switches also serve this purpose.

As these gadgets find usage in different working environments, it is necessary that they are robust, water resistant, shock resistant and portable. There are both corded and cordless (battery operated) varieties and the latter are best suited, as they can be moved from place to place without the intrusion of wires and the need to look for electrical sockets to plug in. A few models allow both corded and cordless operations. Another beneficial feature of these lights is their flexibility, which allows precise positioning of the device. There are models that come with adjustable legs that enable the device to clasp on to almost anything. Features that prevent heat emissions and hazards that may follow are vital.

Most of the battery operated models come with built in NiMH rechargeable batteries. ABS casings and rubber bumpers provide the necessary resistance against impact. The compact type of work lights can be kept in vehicles for emergency situations. Work lights are also used in remote locations and for rescue operations too.
