![]() While most devices don't tend to truly achieve the maximum advertised values due to ISO standardized allowances for manufacturing deviation, the unit should ideally clock in at 400 or more ANSI. This is quite a bit off from the 500 ANSI Lumens that the device advertises. The Emotn N1 clocked in at around 115 Lux before considering any device-specific variances across the surface area of 2.75 square meter, which results in approx 315 ANSI lumens. Lastly, as measuring the nine zones is a manual process, some variance is expected, especially with short throw and ultra short throw projectors, as one has to point the measuring device at the light source instead of laying it flat against the wall as with classic projectors. The used measuring device has a variance of 4%, which should be taken into account when considering the final result in lumens. While the projector's brightness and contrast may be adjusted to see the eight shades of gray in a control image, we test the unit at its default settings. This includes a nine-segment white screen across the 100" or 2.75 m² canvas in a dark room where the ambient luminance (it boosts the values of the digital light meter) around the area of the projected image is just under 1 Lux. We test real world luminance the same way ANSI lumens are measured. It is set in a living room with natural sunlight from the left and ceiling lighting from the right. To evaluate the projector we are using the Grandview Dynamique DY3 100" ALR screen, which provides a 140° viewing angle and gain of 0.4.
