Nothing comes up for that search. When I say spec(ification)s I mean more than just initial lumen output. It used to be difficult to find a spectral graph on a given bulb, but now it's quite common. It used to be difficult to find a bulb with a Kelvin color temperature rating, again, now it's quite common. Bulb life would be another specification I'd be curious about.
But, know this about all MH bulbs--they're typically going to be more blue than HPS because they emit a different range of wavelengths. They give off UV radiation whereas HPS does not. If you're talking about a bulb that's, say, 10,000K, that's a bulb that's intended for going over something like a planted aquarium or reef tank, it's usually where we would want a very strong peak in the blue end of the spectrum.
So, I'll go and try *again* to see if I can find what bulb you're talking about, but you could throw a dog a bone here and link it yourself. ;)
Is it this bulb?
If so, anything at 6,500K is going to look blue to our eyes. 5,000K would look less blue and is closer to what we perceive in daylight.
