I'm not aware of any calculator that you have ever used being accurate.
That's because the manufacturers posts BS numbers for their brightness and the calculators use the brightness that the manufacturers give.
What is the actual brightness of your Epson 5030? NOT THE CLAIM!!! Go find a review, read it, and find out how much brightness you are probably getting. (hint: About 1,500-1,700 lumens)
Now, do the same for the BenQ. (hint: also about 1,700 lumens, but color won't be as good - research dlp color brightness)
There is your apples to apples comparison.
Kind of like contrast ratio, brightness is often a BS number, especially in the world of DLP projectors with so many models that have clear segments to boost white brightness, but with color brightness that is often quite dismal.
A 'light canon' is a subjective term.
