Keeping in mid that these are new lamp numbers that will drop in half - those are the ranges I would use with each room bracketed based on the amount of ambient light and margining for lamps, screens, specs being a WAG...But the low side of their range accounting for the lamp average is meeting SMPTE film&TV specs.
Replace them with averaged lamp life brightness and it is more reasonable - 12ftL for dedicated room - 24ftL if you want sconces on.
Also if you do contrast ratio at ambient math - you see you need some serious lumens
(ON+AMB)/(OFF+AMB)
