In daily household use, projectors are generally more power-saving than traditional TVs of the same screen viewing effect, and the power gap is more obvious when pursuing a large-screen viewing experience. Many users mistakenly believe that projectors with built-in light sources consume more power, but in fact, the power consumption design of household projectors is more energy-efficient compared with LCD and OLED TVs. The specific power consumption is affected by screen size, brightness gear, and device type, but the overall power-saving advantage of projectors is undeniable in most usage scenarios.

Taking mainstream household devices as an example, a 55-inch smart TV commonly used in families has a power consumption of about 120 to 180 watts during normal operation, and a 65-inch TV can reach 200 to 250 watts. In contrast, ordinary household LED projectors only consume 50 to 100 watts in standard brightness mode, and even high-brightness smart projectors rarely exceed 150 watts. When watching videos for the same length of time, the power consumption of the projector is far lower than that of a large-size TV. Especially for users who like 100-inch large-screen viewing, using a projector can save nearly half of the electricity compared with a 100-inch commercial TV.

Moreover, projectors have more flexible energy-saving modes to further reduce power consumption. Most projectors are equipped with eye-protection mode, eco-mode, and silent mode. After turning on the energy-saving mode, the device will appropriately reduce brightness and power consumption without affecting basic viewing, and the power consumption can be reduced by 30% to 40%. When the projector is in standby state, the power consumption is almost negligible, while the standby power consumption of smart TVs with various background functions is slightly higher. In the long run, using a projector for home video watching can effectively reduce household electricity costs.
