Home Forums Hunting & Shooting Hunting Optics 30 mm vs. 1" tube scopes and exit pupil - Please clear it up

I get confused sometimes reading that 30 mm scopes can't be any brighter than 1" scopes, and the same with 42mm vs 50 mm?

So, if scope specifications lists a 3-9x50 30mm scope having an exit pupil of 5.7, and a 3-9x42 1" scope having an exit pupil of 4.4, then the larger scope lets in more light, right?
Thanks,
