To get the brightest image projected by Mars II Pro, please change its image mode to Standard Mode by going to Settings > Projector > Image Mode > Standard Mode. 

Because of its portable design, we're only able to offer 500 ANSI Lumens in this little guy. Better brightness would create more heat, and more heat would have required us to make Mars II Pro a lot bigger to keep it cool. For best use, use Mars II Pro in a darker environment.

If there are still any issues or concerns with the brightness of Mars II Pro, please contact us and make sure to mention that you changed the image mode to Standard Mode so our agents can quickly find a solution for you.
