Very true, I'm sure the difference between the two is pretty small. Thanks for the help

Ok, just incase anyone else ever wonders, I did some math.

I found pictures of each beam one meter from a wall, used geometry to figure a few things out:

The angle of the WF-606A is 52 degrees
The angle of the C3 is 53 degrees

At a distance of 20 meters:
The bright spot diameter:
WF: 5.2m
C3: 5.8m

The flood diameter:
WF: 25.6m
C3: 26.6m

Math solves everything
