I have noticed light power is now expressed in lumens instead of candle power. I had gotten used to candle power and have no idea how lumens compares.
When it comes to “Lumens”, there are ‘Chinese Lumen’ which are just made up, versus ANSI Lumens, which are an actual standard.
One light can be 1,000 Chinese lumens and actually be a couple of hundred, while the ANSI standard uses the actual lumens.
Myself, I only buy lights that have regulated battery life, an unregulated light is only as bright as the battery is fresh, regardless of what the claim is.
Candlepower and Lumens don’t compare, they are two different things.
