ANSI Lumens vs. Light Source Lumens – Which matters?
ANSI Lumens: Industry-standard measured brightness (9-zone average). Always reference this metric.
Light Source Lumens: Raw output of lamp/laser module (often inflated). Actual image brightness ≈ 30% of light source lumens.

Should I use Front Projection, Keystone Correction, or Ceiling Mount?
Front Projection: Zero distortion, optimal image quality (recommended).
Keystone Correction: Compensates for angled placement but reduces effective resolution (emergency use only).
Ceiling Mount: Space-efficient, avoids obstructions (requires pre-wiring for home theaters).
