One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s One watt is also defined as the current flow of one ampere with voltage of one volt. 1W = 1V × 1A Lux to watts calculation » Currently, we have around 5667 calculators, conversion tables an...
Enter the luminous flux in lumens, luminous efficacy in lumens per watt and press the Calculate button to get the power in watts:Enter luminous flux in lumens: lm Enter light source: Or enter luminous efficacy in lumens per watt: lm/W Power result in watts: W...
The old days of choosing light bulbs by wattage are over. With today’s modern LED bulbs, we instead need to focus on lumens. But what is a lumen? We’ll explain that, and then you can use our lumens to watts conversion chart to select the right LED bulb every time. ...
This corresponds to 683 lumens per watt of radiation at approximately 555 nm wavelength, which is near the maximum of the standard photopic spectral luminous efficiency curve. LUX: one lumen per square meter; differs from foot-candle by about a factor of 10. Quantum Units, Photon Flux Density...
