"The light processing components of a projector consist of the projection lamp, which determines the highest brightness output, and color wheel, which controls color performance. Theoretically, a higher wattage lamp can produce a brighter image while the color wheel’s RGB purity must be controlled in order to reproduce colors accurately. Light transmission, and therefore brightness, will be compromised when it is necessary to meet pure color requirements. So instead of pursuing high lumens, projection brightness must be controlled within an appropriate range to increase color accuracy.
