Mr. Guns ‘n Gear reviews the new Strealight models. For reference, 1 Candela emitted over a 4π solid angle = 12.566 lumens. Lumens is the total amount of light emitted. Candela is the light sent in a direction of a particular solid angle, so he’s referring to the tightness of the light pattern.

Thanks for the quick lesson and math on Candela vs. lumen. Interesting. Comparing different product offerings based on the labeling can be challenging.

Correlating this to nuclear engineering, Candela is “source term.” Lumens is “flux.”
