The Lezyne Macro Drive at 800 lumens lasted a full three hours (This is well above the manufacturer stated run time for the Lezyne). At the 600 lumen setting the Taz 1200 lasted two hours and forty-nine minutes. Now you know the correlation between lux and lumens in connection with distance and angle. So here is the real kicker with the Taz 1200. In order to ensure homogeneous lighting with a corresponding lux value, a professional light planning should be involved. The positions of the individual lights are chosen in a way that the light cones overlap. Automotive Lighting Automotive Maintenance & Equipment LED (Light Emitting Diodes) Emitters, Lasers, Sensors LED Light Engines and Modules Light Management. So the illuminance in the light circle is not homogeneous.įor the complete illumination of rooms or specific areas with a minimum illumination intensity, in most cases several LED luminaires are used. Especially in the peripheral areas, the luminous intensity usually decreases. When using a single light source, it should be noted that the light distribution of many LED spotlights does not always have to be uniform within the beam angle. A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux. After a click on the Calculate button you will see the size of the illuminated area and the lux value. Select Lumen to Lux in the calculator and enter 470 as the lumen value, 110 as the beam angle and 6.5 for the distance. You want to find out how much lux the table is illuminated with. Example: A spotlight with a beam angle of 110° and a light output of 470 lumens is mounted at a height of 6.5 ft above a table.
