Christie Roadster HD20K-J for projection mapping
20,000 lm for the price of a mid-range projector — but xenon lamps are costly to run. A touring legend: 20,000 lm 3-chip DLP in a rugged frame, with lenses from 0.67 to 10.4. Old but very cheap used for the brightness. Xenon lamp: high running costs, and it needs serious power and cooling.
Typically $800–2,000 used
