Dual beam
Worklights with dual beam combine two light groups with different lighting characteristics in one housing. Usually, a combination of a flood beam with a switchable spot beam is used, whereby the flood beam is usually used as the main function and the spot is only switched on when working in a specific area. An example is a dual-beam worklight on a forklift truck, where the area in front of the vehicle is generously illuminated by the flood and the spot (directed upwards) is only switched on when the load is lifted.
On headlights with combined low beam and high beam, dual beam means that the low beam remains on even when the high beam is switched on.
