As mentioned on the previous page, the Optoma HD143X has a lamp life of up to 15,000 hours. This is in what they call their Dynamic power mode – that is, their most economic ECO mode. ECO Mode has a lamp life of up 10,000 hours, while the Bright, full power mode comes in at 3,500 hours.
That 3,500 hours is typical of lamp based projectors at full power. Now, with a projector this bright, you won’t really need to keep it at full power unless you’re watching during the day. ECO or Dynamic will be suitable for night viewing, when your room is fully darkened.
So, utilizing the projector’s ECO modes, you should expect the lamp life to be anywhere between the low end 3,500 hour and high range 15,000 hour mark. It’ll all depend on how well you pay attention to the power modes you are using, and utilize the ones that are best for your lighting conditions.
