Watt for watt the 5000-6500k spectrum will probably have better par than an 8,000k, or a 10,000k, the higher you go, the less reds and yellows you have in relation to the blues and purples. But when you have major overkill lights such as an HQI, your photosynthesis will be maxed out even at a higher Kelvin. I'd just keep it at 10,000k or under, but if you are at low light already, probably stick to the 5-6500k.
