Nope, no and no lol
315W is the actual watts used by the lamp, maybe 340 with ballast.
Kelvin temperature gives an idea of color and spectrum, but it's only a very general guide.
The reasons for its efficiency include both that its spectrum output is superior to HPS, plus the low frequency square wave ballast tech. This drives the lamp more efficiently.
Folks seem to be coming to agreement that a 315W CMH system is worth maybe 500W of HPS in equivalent growth performance.
Oh ok, that makes more sense. Thanks for the knowledge!
