Having the brightest flashlight can make one really feel special, a standout. However just how is the brightest flashlight determined? There is really greater than one means to gauge illumination and thus contrasting means of marking one light as being brighter than an additional.
A flashlight could be brightest in a qualitative sense even though another one might result much more total lumens or have a higher luminous strength. Marketing experts, aware of customers' tendency for desiring the brightest flashlights, will certainly make their claims based upon that measure, whether subjective or unbiased, placing their products at a benefit.
Candlepower, now an essentially outdated term, shows the stamina or strength of a specific light beam. Today, a similar measure is the number of lumens per unit area. This is appropriate if the application calls for a directly focused beam, possibly in order to illuminate items at a significant range from the audience.
