Eco mode on projectors
A high luminous flux, measured in lumens, is generally a quality feature when buying a projector. It determines the maximum image brightness. However, you don't need that very often, and a reduced-light mode is then sufficient. Projector configurations often offer this as Eco mode or power-saving mode, and it differs significantly from dimming the image using the brightness control. In Eco mode, the projector lamp receives less power. As a result it produces less light and the image becomes darker, but this also means lower power consumption, less operating noise and a longer average lamp life.
Lower power consumption and longer lamp life are economic and ecological arguments for Eco mode. But a reduced-light mode is also immediately noticeable in a pleasant way, because it reduces the projector's operating noise. As the projector lamp also produces less heat at the lower brightness of power-saving mode, the fans in the projector don't have to run at full power either.
