Both lumens and candlepower are used to measure light intensity. Put simply, lumens is a unit describing the TOTAL output of light from a light source. It has nothing to do with the reflector/lens assembly of the device. On the other hand, candlepower is a measurement of the brightest spot in the output beam. The reflector/lens mechanism definitely plays a part here by focusing the light. Lumen Example: A dinner candle provides about 12 lumens. In comparison, the DEWALT 3C flashlight provides 141 lumens.
