Beam spread of Cree CR6 vs CR4

Posted by ccolby (My Page) on

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?

See the specs. Note that the CR6 spec covers both the 800L and 575L versions, if you are comparing candlepower. The CR4 is a tiny bit wider, but I doubt that one would notice.

Thanks. Yes, I did study the beam spread graphs on Cree's site, and they do look similar. But I was hoping to find someone who has seen both and could give me a more subjective judgment.

I like your username, by the way.

You could kludge up a way to hang a 4" Cree in a 6" can, and see for yourself.
