Beam spread of Cree CR6 vs CR4
I'm considering retrofitting Cree CR4 lights throughout my house. I currently don't have any 4" cans, but I do have a couple of 6" cans, so to test out how these lights look I went to Home Depot and bought the 575 lumen version of the CR6 (ECO-575L). Since the CR4 has the same lumen output as the 575-lumen CR6, I figure this will be a good test. But what about beam spread? I know that 4" lights can sometimes have a narrower spread than 6" as a general rule. But has anyone compared the CR4 against the CR6 specifically? If I'm happy with the CR6 beam spread, will I be happy with the CR4?
