All Lumens are not the same!!! Learn why ISO Lumens and ANSI Lumens Are the Industry Standards.

Thank you for keeping those manufacturers honest! It is very unfortunate that these measurements are not regulated and standardized! Marketing is always pushing for higher numbers to fool customers!

Great video, more projector manufacturers should adopt a standardised way of measuring brightness. It is too confusing for an average customer to make a good decision. If ANSI is adopting the same methodology as ISO, how come the ANSI lumens value seem to be lot higher than a ISO Lumens. Formovie used to advertise as 2800ANSI Lumens now they are saying 1800 ISO Lumens.

I like your idea of rating the projector's brightness according to its useful purpose (Category: Portable, Small, Medium, Professional), but on a Scale 1-100,1-5 seems to have too many percentage gaps (Less Precise). Also, stating brightness as an ANSI Lumens or just say "Lumen", only because when I hear ISO my mind thinks photography. But, in any case a standardized Lumens that can be measured against itself as compared to another's comparative brightness. I would not worry about the sliding scale from 2024-2030 let's say as it is compared to the time and date you took the measurement, because that to me is constant shifting goal post. I think the one area these companies should measure is the brightness for each color range, different the total color availability. Keep in mind we are all looking to buy the best bang for our buck, we might geek out too much on each stat, that we forget how much nicer we have it than 20 years ago.

Thank you for the videos clarifying the variables in projectors. As you mentioned in the videos, the screen is critical in the overall display performance. Would you all elaborate on screens, esp why the manufacturer’s gain ratings rarely match the actual gain?
