A:Answer It last a long time like maybe 8 or 9 years but i personally feel like it's a ripoff to spend $20,000 for something i'll never be able to use again after a few years. And after a few years before the lasers go the projector will get dimmer. So if it's 2700 lumens which is low to me, it will be like 2300 lumens down the line and lower. They need to make these projectors more advantageous in pricing.
