Rather than hijacking a thread where #12 posted about rpm cube rule.............
Does anyone know how much to increase lumen output to double light level?
4 times? Square rule. Cube?
Ignore the details if possible. Just ball park.
Over head light (high bay) outputs 120 degree pattern.
For example. If I have a 5,000 lm source now and want to double the light level in the area covered by the 120 degree pattern.
More questions to follow if there's an expert here.
