WebCandlepower (abbreviated as cp or CP) is a unit of measurement for luminous intensity. It expresses levels of light intensity relative to the light emitted by a candle of specific size and constituents. The historical candlepower is equal to 0.981 candelas. In modern usage, candlepower is sometimes used as a synonym for candela.

WebMultiply candela by 12.57 to convert to lumens. For example, the 20 watt lamp used in the SL-35X is rated at 450 lumens or 35.8 Mean Spherical Candela. Peak Beam Candlepower. Peak Beam Candlepower is a measure of the brightest spot in the focused beam. It is a function of both the output of the lamp and the efficiency of the reflector. WebIt is almost solely a function of the lamp, and for practical purposes is equal to the lamp output which lamp manufacturers rate in Mean Spherical Candela (Sometimes called Mean Spherical Candlepower), or in lumens. Multiply candela by 12.57 to convert to lumens. Webluminous intensity lumen/steradian or candela. Lumen: It is the unit of luminous flux. It is defined as the luminous flux emitted by a source of one candle power per unit solid angle in all directions. Lumen = candle power of source × solid angle. Lumen = CP × ω. Total flux emitted by a source of one candle power is 4 π lumens. Candle power ... do you have to check in online with tui
