p.1 #1 · Light measurement for AB's etc..


It's such a PITA trying to compare light energy from specs that I thought I'd ask a question here.

Can someone tell me what f stop you get from an AB800 and an Einstein at ISO100, standard reflector, 2 Meters at full noise ?

This would help me compare energy output in a meaningful comparison to my current lights. 't' times etc are a secondary issue right now so just trying to see if they will drive my modifiers with enough output at this stage.

Thanks

1 meter = 39 inches, or 3 feet 3 inches.
