To get the brightest image projected by Solar Portable, please change its image mode to Standard Mode. Go to Settings > Projector Settings > Image Mode > Standard Mode. 

Because of its portable design, we're only able to offer 400 ANSI Lumens in this little guy. Better brightness would create more heat, and we would need to make Solar Portable much bigger to reduce heat. For best results, use Solar Portable in a darker environment.

If you still have issues or concerns about the brightness of Solar Portable, please contact us and make sure to mention that you tried switching to Standard Mode to help us find a solution for you much faster.
