Before you ask
Common questions
How many lumens do I need?
It depends on image size and room light. Roughly 6–7k lumens for a 4 m screen in a normal room, 12–15k for 5–8 m or bright halls, and 20k+ for outdoor mapping. The planner above gives a starting point; we confirm on survey.
Do laser projectors need lamp changes?
No. Every Wincomn / Krinda model uses a laser light source rated 20,000–30,000 hours — years of normal use with no lamps or filters to buy.
Can the projector sit far from the screen?
Yes. Most models take interchangeable motorised lenses from ultra-short throw (≈0.3–0.5:1) to long throw (up to 8:1), plus lens shift, so placement is flexible.
Can several projectors make one big image?
Yes — built-in warping and edge blending join units into one seamless wide, curved or dome image for halls, mapping shows and simulators.
Do you install, align and service them?
Yes — mounting, lens and geometry alignment, blending, control integration and local after-sales support with the 3-year manufacturer warranty.
