The Converter of the light flux of the led online calculator


Our online calculator will help you in translating the luminous flux of light from the Candela to lumens and Vice versa.
Luminous flux is the quantity of visible light that is formed by the LED light source and it consists of the following metrics: lumen output, wattage used chemical compounds, the quality of the lenses.
Lumen (LM) is a unit of measurement of luminous flux and it shows how much light can emit light bulb in all directions.
Candela (CD) is a unit of measurement of intensity and indicates how much light can emit light in one direction.
Half-value angle of the led depends on the design of the lenses and transparency of the case, the LEDs with a frosted bulb have large angles half brightness and light brightness, and the LEDs with a transparent flask in the form of spherical lenses usually have a smaller half-value angle, and the same luminous flux, the intensity of the light source with a small beam angle light more than the source with a large angle.
To use the calculator you need to specify the parameters in myllyluoma (MLM) or millicandela (MCD) and specify the beam angles from the led, as it is written in the specifications.
