Christie has the CP4415m-RGBH at CEDIA in Denver, and the part that got my attention is not the 15,000 lumens. It is that a projector already installed in commercial cinemas is being pitched at residential rooms. The RGBH family turned up in late 2025 as a cinema product and nothing about it was redesigned for the house. It weighs 132 pounds, pulls around 1,060 watts, carries its own liquid cooling loop, and Christie says it covers screens up to 52 feet wide.
For scale, take the projectors people here actually shortlist. JVC's DLA-NZ500 is rated 2,000 lumens, Sony's BRAVIA Projector 7 at 2,200, Epson's QB1000 at 3,300, and even the BRAVIA Projector 9 only claims 3,400. The Epson QL7000, which exists specifically for enormous screens and rooms with light in them, tops out at 10,000. Christie wants another 50 percent on top of that.
The imaging side is the genuinely interesting bit. A 0.98-inch three-chip DLP Cinema block at native 4096x2160, one DMD per primary, so no colour wheel and no shifting to build a 4K image. That is the thing single-chip owners quietly wish for every time they catch a rainbow. Contrast is where I would slow down: Christie quotes up to 6,000:1 full-field on/off, and it specifies peak brightness using the high-brightness cinema lens while quoting peak contrast with a UHC lens. Those two numbers do not arrive together, and 6,000:1 in a properly dark room is not going to embarrass a JVC.
No residential price has been published anywhere I can find. Which leaves the real question: if your room genuinely needs 15,000 lumens, is the honest fix a bigger projector, or did you build a room with too much glass in it?
