The Ricoh UHL3660 is a $6,000 professional 4K Ultra Short Throw (UST) laser projector featuring an OptiBright dual-laser light engine that achieved an impressive 6,973 ANSI lumens in testing, exceeding its 6,500-lumen rating. It utilizes a large 0.65-inch Texas Instruments DLP chip with XPR four-way pixel shifting to project crisp UHD images, which offers superior contrast, better heat dissipation for 24/7 use, and less "screen door effect" than competitors using smaller 0.47-inch or WUXGA sensors. Designed for challenging ambient light environments like boardrooms and museums, it includes advanced geometric alignment tools, an IP6X dustproof sealed enclosure, 360-degree installation versatility, and Natural Color Enhancer technology covering 87.8% of the DCI-P3 color gamut. The review highlights strong pros, including its highly competitive price point, exceptional brightness, an extensive light source lifespan of up to 40,000 hours in long-life mode, and a high-quality lens with excellent corner-to-corner focus. Its built-in image blending allows easy multi-projection setups without external hardware, and the dual-laser design provides redundancy, allowing the unit to stay operational at reduced brightness even if one diode fails. On the downside, the...
