WebMay 10, 2006 · Lumens, as said before are total light output. CP, basically, is intensity at one spot. CP is a function of focus, lumens measure how much light is coming off the bulb BEFORE getting focused, generally they are not convertable. So, you can have a maxabeam with 1,000,000 CP be overall less bright than a 500 watt halogen. WebMar 15, 2013 · Candlepower is generally used to describe the light distribution of directional light bulbs like an MR16 or a PAR30. The amount of light on a surface is determined by dividing the candlepower of the light source by the distance squared (the inverse square law). The ratio is 4:1. Thus the further away the light source, the less light strikes the ...

WebLux to candela calculator Candela to lux calculation Candela to lux calculation with distance in feet. The illuminance E v in lux (lx) is equal to 10.76391 times the luminous intensity I v in candela (cd), . divided by the square distance from the light source d 2 in square feet (ft 2):. E v(lx) = 10.76391 × I v(cd) / (d (ft)) 2. Candela to lux calculation with distance in meters WebLumens to candela calculator Candela to lumens calculation. For uniform, isotropic light source, the luminous flux Φ v in lumens (lm) is equal to the luminous intensity I v in candela (cd), . times the solid angle Ω in steradians (sr):. Φ v(lm) = I v(cd) × Ω (sr). The solid angle Ω in steradians (sr) is equal to 2 times pi times 1 minus cosine of half the cone apex angle … WebDec 28, 2024 · This means illuminance parallels magnetic field in the way scientists and engineers calculate it, and you can convert the units of illuminance (flux/m 2) directly to watts using the intensity (in units of candelas). You can use the equation. \Phi=I\times\Omega Φ = I × Ω. iphone ringing sound effect
