6000K not 6000C.... thats some serious heat.. no way I dare have that in my house.. looks cool as fuck though

6000K is the 'colour temperature' and has nothing to do with heat. that value tells you what colour the light is. for example you can have 4000K (cool white) or 2700K (warm white) CFL lamps. and you know that none of them heats up to that value.
the lower the value is, the more red light you get. the higher the value is (speaking for white), the coulour has more blue spectrum. this 6000K would be good for vege, but in flowering you would need some more red spectrum.
