You do not have enough info to make the calculation, sorry it is not a linearly proportional relationship.

Rule of thumb, if it is quaoted in candlepower, it isn' t any good.

I make LED lights for fun, even lumens isn't that easy as different companies measure different ways.

My headtorch is ~3000lm, that is bright enough even for commuting. When driving with cars makes sure your lights are just as bright.
