SEO meta: How to pick a budget 4K projector — real lumens vs claimed, throw distance, lamp costs, and the honest parts that matter.
Budget 4K projectors have never been better or more confusing. The spec sheets lie in three predictable ways, and knowing them is the difference between a home theatre and an expensive flashlight. Here's what actually matters, in order.
A "$800, 3000-lumen" projector claims its LED-source number, not ANSI lumens. Real-world usable output on budget 4K units runs 1,200-2,200 ANSI. In a light-controlled room, that's plenty. In a living room at dusk, the cheapest models wash out. If you can't darken the room, spend up a tier — or budget for curtains.
Budget projectors are mostly long-throw: a 100-inch image needs 8-10 feet. Measure your wall-to-lens distance BEFORE buying, because the projector that "fits any room" on the product page has a very specific opinion about your ceiling. Short-throw costs more; it's worth it in small rooms.
Bulb-based budget units need a replacement lamp at 4,000-6,000 hours ($50-150). LED and laser units cost more upfront and outlive the projector. If you watch daily, do the five-year math before choosing the cheaper box.

The best budget projector is the one whose throw fits your room, whose real lumens fit your walls, and whose lamp math fits your watch habits. The spec sheet knows none of this about you.
