The catch
Nebula Mars 3 Air
A dark setting is what the 400 ANSI-lumen output is intended for.
Side by side
Nebula Mars 3 Air vs Nebula Capsule 3 Laser: Capsule packs down smaller, and the rated 2.5 hours needs Eco on both
Quick verdict
The Mars 3 Air gives you the stronger image and speakers, provided the projector can take up a little more bag space. The Capsule 3 Laser is for buyers whose reason is the smallest two-pound body. Both quote up to 2.5 hours only in Eco mode.
Before you buy
Why, and what it costs you
Published ANSI brightness: how big the gap is
The published “ANSI brightness” figure is 33% higher on Nebula Mars 3 Air: 400 ANSI lumens, against 300 ANSI lumens on Nebula Capsule 3 Laser.
Where this comes from
Higher published output is useful only if your room, surface or workload calls for the extra headroom. It does not, by itself, prove better results. The percentage comes from the lower published figure.
The catch
Nebula Capsule 3 Laser
Darkness and a restrained image size are needed with 300 ANSI-lumen output.
