Lasers work by shooting a really tight beam of light through some fancy mirrors and out the front. Lasers for stage lighting generally have mirrors that allow you to move the beam of the laser around to make shapes in the air and on surfaces that you aim the laser. LED stage lights come in four main types. PAR cans, spotlights, striplights, and "moving head" types. The very best actors have good technique and exceptional talent. Acting techniques, like projecting your voice and movement on stage, can be learned and finessed, improving any talent.
