Barn doors allow the emitted beam to be separately restrained in each of the four directions and provide improved glare control.
A cylindrical anti-dazzle attachment also restricts the view into the luminaire and reduces glare, but without the flexibility of barn doors.
The anti-dazzle attachments are usually externally mounted on the light head. Glare limitation increases with the size of the anti-dazzle attachments. The black painted finish absorbs light and reduces the luminance contrasts.

The honeycomb anti-dazzle screen is used to control the beam and reduce glare. Honeycomb anti-dazzle screens are used where there are high demands for visual comfort in exhibition areas. Its limited depth means that the honeycomb anti-dazzle screen can be integrated within the luminaire. The black painted finish absorbs light and reduces the luminance contrasts.

The cross baffle is used to reduce glare. Cross baffles are used where there are high demands for visual comfort in exhibition areas. The black painted finish absorbs light and reduces the luminance contrasts.

A framing attachment allows various contours of the beam to be adjusted. Reflector-lens imaging systems make it possible to produce a sharp-edged beam. However, a blurred projection results in a soft-edged beam. The separately adjustable sliding components can, for example be used to create rectangles on walls in order to highlight objects crisply around their contours.

The term "gobo" refers to an aperture plate or image template through which light is projected by an imaging projector. Gobos make it possible to project lettering or images.
Reflector-lens imaging systems can be used to create crisp images or even soft-edged transitions using blurred projections.
