Below is an un-scientific test of all the lights.
I shot this on a Nikon D7000, on a F22 setting, ISO 3200, shutter 100
I kept it on F22 so it would let in the least amount of light
I moved all the lights into the Same exact spot, shooting down in the same spot. The camera was on a tripod mounted and was not moved between shots
