Parabolic Aluminized Reflector lights, or PAR lights, or PAR cans, are used when a substantial amount of flat lighting is required for a scene. A PAR can is a sealed beam PAR lamp housed in a simple can-like unit. Like an old-fashioned automotive headlight, the reflector is integral to the lamp and the beam spread of the unit is not adjustable ...
Sealed beam PAR lamp. When the lamp burns out or breaks, the whole assembly must be replaced. A PAR lamp consists of a light source, with lens and a parabolic reflector with a smooth aluminium surface determining the spread of the beam. The most common sealed beam type combines these three elements into an integral unit.
A color scroller, color changer, or "scroller" is a lighting accessory used to change color gels on stage lighting instruments without the need of a person to be in the vicinity of the light. [5] It is attached in the gel frame holder on the outside of a lighting instrument, immediately in front of lens assembly.

A beam projector is a lenseless stage lighting instrument with very little beam spread. [1] It uses two reflectors. The primary reflector is a parabolic reflector and the secondary reflector is a spherical reflector. The parabolic reflector organizes the light into nearly parallel beams, and the spherical reflector is placed in front of the ...
