När du byter ut lamporna kommer du märka att det gamla (och missvisande) referensvärdet watt nu har bytts ut mot lumen. I början kan detta kräva lite tankekraft, Förstärkare beräkning med spänning på 12V DC. För likströmsförsörjning är förstärkare lika med watt dividerat med volt. amp = watt / volt. förstärkare = 800W LED lampor med ett ljusflöde mellan 430-800 lumen (40W-60W) och en färgtemperatur mellan 2500-3000 kelvin.
In the calculator, select Watts to Lumens as the conversion type, enter the value 35 and select the item Light bulb for comparison. After a click on the calculate button the luminous flux is displayed in lumens. The result should serve as a guideline for the brightness of the new LED lights.
Lumens and Lux have started showing up in the specs for video as well as commercial lights, but what are they and how can you use them?
Lumen vs Lux • Lumen is the measure of the luminous flux and is defined as the luminous flux from a light source of one candela through a solid angle of 1 steradian. • Lux is the measure of the illuminance and is defined as the number of lumens per square meter.

Un lux è un lumen per metro quadro. Un piede-candela è un'unità non metrica per la misurazione dell'illuminamento. È usata in fotografia e film, nonché in altre aree. La parola "piede" è usata non in riferimento alle parti del corpo ma alla distanza: un piede-candela è l'illuminamento di una sorgente luminosa di una candela per piede quadrato, misurata da un piede di distanza.
2013-02-23 · Lumens is an absolute value – it’s the amount of light emitted by a light source (bulb), so 100 lumens is 100 lumens whether you are 5 inches away from the bulb or 10 feet away. Lux is the amount of brightness that reaches you from a light source – how bright you perceive a bulb to be. In the calculator, select Watts to Lumens as the conversion type, enter the value 35 and select the item Light bulb for comparison. After a click on the calculate button the luminous flux is displayed in lumens. The result should serve as a guideline for the brightness of the new LED lights.
