Roughly 6-months after Optoma unveiled its CinemaX P1 Smart 4K Laser Projector, the company is back with three new offerings. Two of these models are Optoma laser projectors with brightnesses that reach up to 4,200-lumens. To put that into perspective, CinemaX P1 has a brightness of 3,000-lumens. Massive 300-inch screen sizes can be achieved and 30,000-hour runtimes yield a theoretical lifespan of around 40-years when watching a full movie each day.
