Then Anker started a Kickstarter campaign on January 11, 2022, for its newest, brightest, portable projector yet: the Nebula Cosmos Laser 4K - touted as “the most compact 4K laser theater” with a 2,400 ISO Lumen rating. The Cosmos Max was a good, mid-range 4K projector geared towards the stationary home cinema, but at 1,500 ANSI lumens, it was not bright enough to replace my Samsung 4K LED television. This review will go over some projection basics and what makes a projector better than another.įollowing the evaluation of the Mars II Pro (which was bought with my own money), Anker sponsored their Nebula Cosmos Max 4K that I had compared against the equivalent Xgimi Horizon Pro‘s published specs. How could that be? The Halo was rated with an 800 ANSI Lumen brightness rating (see “Projector Basics” section in this review to learn more) that should have made it brighter than the Mars II Pro’s 500 ANSI Lumen - but in a side-by-side comparison, my eyes could not discern a noticeable difference. The Xgimi Halo (1080p) had superior specifications and a higher-end experience, but I often found myself gravitating towards the Nebula. It had been perfect for camping with its built-in battery that lasted long enough for 1-2 movies and had great sound and brightness. The Anker Nebula Mars II Pro (720p) has remained my favorite, portable projector since I bought it over 1.5 years ago. ANSI/ISO Lumen-to-Room Size Recommendations.
