Is SSC P4 still the smoothest?

[Gary123]

What is the most efficient emitter right now (lumens per watt)? Is it the XP-G?

AND ..................

Is a P4 still the smoothest thing out there (don't have any SST-50's or 90's, and heard the Golden Dragons were very smooth). I'm not talking about a flood type beam, but something that is brighter in the center.

Thanks

Yes, the XP-G is the most efficient available emitter.

Although Cree currently claims 186lm/w at (I think) 4700kelvin, at 350milliamp, at room temperature in the laboroatory...
