Lux out put question


New Member
I have read that unless there is a 50% or greater increase in lux measurements it is hard to actually see the difference?

That being true then what is the benefit of buying a light that outputs 16000 lux at 1 meter rather than a identical but less powerful model that outputs 11000 lux at 1 meter with the same spill kill fitted to both?

With out access to lights to test how do decide if there is that much difference between the two lights?

It may be more difficult for our eyes to tell the difference but it makes a difference for the camera, film or digital.
