Attention! When measuring the brightness of the light, set the engine speed to 2000 rpm-1, to keep the battery in the charging state.
2. If a luxmeter is used to measure the brightness of light, then it is necessary to convert its readings into photometer units using the following formula:
I = ER2, where
I – equivalent brightness, cd/m2;
E - illumination, lx;
R is the distance in meters from the headlight to the light meter.
