Let there be LIGHT
With light breaking through the darkness, a unique space and period are revealed on stage. Light is indispensable to the theatre, but how much do you know about different lighting instruments?
It is the most common kind of soft-edged light, named after the lens it uses - which is invented by French physicist Augustin Fresnel. Its beam has a soft edge and will spread a considerable amount of light outside the beam. The beam can be adjusted into larger or smaller circle by sliding the lamp closer to or farther away from the lens. This kind of lighting instrument cannot project gobo images, but it is a cheap way for stage lighting, especially at close and medium ranges to the subject.

Its beam is bright, intense and durable, but it cannot be focused or given any kind of sharp edge. It is suitable for a wide range of duties, especially band shows with smaller budgets, due to its low cost and light weight.

It has a longer body than Fresnel, with all of its lenses mounted in a movable barrel that can be slid back and forth, hence the light it produces can be either hard- or soft-edged. Having a reflector shaped like an ellipse, it can focus light more precisely with little spill. This sharp beam enables the light to project gobos as well as using shutters to project a specifically shaped light beam. Ellipsoidal is suitable for projections and for lighting at medium and long ranges from the subject.

It is a movable lighting instrument operated by an operator to emphasize or illuminate or follow a specific performer on stage. Size of the light circle is determined by the iris. Theatres of different size shall need follow spots of different size. The distance from the follow spot to the stage, throw distance, is required in order to determine which spot is needed.

Barn doors are a set of flaps that can be swung in front of the lens of lanterns producing soft-edged light, masking off part of the light emitted.
Part of the light emitted is masked off (before barn doors are used, the lighting area is circular in shape; it becomes rectangular after barn doors are used)
