Dual beam
In the context of a work light, dual beam refers to the combination of two different light distributions or light functions within a single headlamp.
The lamp features separately controllable light groups, which can be used to produce different beam patterns. Depending on the model, the light groups can be operated individually or, where applicable, together.
Two light distributions in a single light
A dual beam light can, for example, combine flood illumination with a more tightly focused spot. This allows the light distribution to be adapted to different working situations without the need for two separate lights.
Which beam patterns can be combined and how they can be switched depends on the specific version of the light.
Dual beam is not a beam pattern in its own right
Unlike flood, trapezoid beam or spot, dual beam does not describe the geometric shape of a specific light distribution. Rather, the term refers to the technical combination of two light distributions or lighting functions within a light.
The actual illumination pattern produced must therefore be assessed on the basis of the respective beam patterns and, where applicable, the lighting diagram of the light.
The article beam patterns of work lights provides an overview of the most common beam patterns.
