No doubt this can vary a lot, as by running a filament hotter, one can trade off lifetime for intensity. A quick Google search yielded an article that says 1 lumen = 1 foot-candle, and that to an approximation, dividing the lumens by 0.07958 will give an approximation of candlepower.
Some 60 watt soft white "long life" bulbs here claim 780 lumens with a 1500 hour life. That would work out to about 9800 candlepower.
I suspect there are some assumptions made that might be good to know about. But that exhausts my knowledge!
