We are offering here the spot lights that are an effective way of illuminating a whole room, as they can be usually adjusted to point in a direction of choice, changing as required. They are more complex than directional light and point light and essentially borrow stuff from both. They are most commonly used in concerts, musicals and large scale presentations where highlighting a specific mobile individual is critical. They are sometimes located overhead on catwalks. They are used in front of lights to project a picture effect upon the stage. The spot lights are made in various designs.
