Lamp projectors draw 250 to 400 watts, several times a TV of similar picture size. LED and laser projectors use a third to half as much and their light sources last far longer.
A typical home projector (250 W) costs $0.046 per hour, or about $2.75 per month at 2 hours a day in the US. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |

How to lower the cost of running a home projector
- Use eco lamp mode. It cuts power by 20 to 30 percent and extends lamp life.
- Watch in a dark room so you can run lower brightness.
- Unplug it between uses. Some models keep fans running in standby.
In standby it draws about 1 W, which adds roughly 9 kWh ($1.61) per year if it is never unplugged.
