Lumens vs. candlepower | Candle Power Flashlight Forum Candlepower = light intensity typically measured at one spot, typically the brightest spot there is Lights that aren't focused are still measured at a small area spot and thus have lower candlepower ratings Lumens = total light output over the entire area lit by the device, focusing light into hot spots doesn't affect lumen output as spill is also measured In the past incans being a lot
Candlepower To Lumens??? | Candle Power Flashlight Forum A lot of flashlight mfg,s give the candlepower of there lights And still more give lumens How do I convert candlepower to lumens?? Also if a light gives out 300 lumens, is this bright or not?? Looking for answers
1 Million CP = How Many Lumens? | Candle Power Flashlight Forum Candlepower tells you how tightly focused the beam is, assuming the light source has a lens or reflector to focus the light into a beam Lumens can be measured quite accurately, using an instrument called an integrating sphere, and identical lights would all have similar lumen values
Candle power to lumens? | Candle Power Flashlight Forum If it was 2 million candlepower overall (at any angle) that it will have 2 5 Million lumen And the ratings aren't even correct, they are way under 500,000 candle power at the most focused spot Short answer, candle power can not be converted to lumens unless it is the same at every angle of measurement A usual 1 million candlepower light produces 300-600 lumen, I read that somewhere
lux vs lumens vs candle power | Candle Power Flashlight Forum Candlepower (Candela) is the output over a certain angle It is directly related to Lumens 1 Lumen (Lm) = 1 Candela (Cd) Steradian (A complete sphere is 4*pi steradians) The difference is that the candlepower is usually measured at the brightest part of the beam to make the light look better Lumens always measures the total light output
lumens vs. candlepower | Candle Power Flashlight Forum Lumens is what is used to specify the total amount of light coming from any light producing device, and candlepower refers to the highest value of the light intensity to be found anywhere in the lights "beam" Lumens tell you how "powerful" the light-producing device is, be it a light bulb of any type, a flashlight, or a car headlight
Question on Lumens vs. Candlepower - Candle Power Flashlight Forum Candlepower and lumens measure different things and cannot be converted into each other Candlepower gives you a measure for the highest brightness in the beam, but this only refers to one point in the beam
Candle Power vs Lumens, whats the difference? Candlepower is a measure of the peak beam intensity- the intensity at the very brightest spot, whereas Lumens, put simply, is a measure of the total radiated light output in all directions
