One candlepower isotropically (radiating in all directions) produces an illuminance of one lumen per steradian. Illuminance is a measure of photometric flux per unit area, or visible flux density. Illuminance is typically expressed in lux (lumens per square meter) or foot-candles (lumens per square foot).
Thus, the simple answer to your question is that a 60 candle power lamp would be the same as a 60 lumen lamp. Which is true. If both are radiating isotropically. Which they are not. Since the beam qualities of flashlights vary radically, meaningful comparisons based on factory specifications cannot be made.
Check some old posts for the actual comparisons of various flashlights for the most useful data.
