I personaly would go with the AB 10K, its actualy output is a true 13.5K which gives a nice crisp white with a tiny hint of blue.. then a couple VHOs round it off to amazing.. not only are you getting nice coloe but not much beats the AB in PAR output and if on a good proper ballast you can get up to 2 years out of them (mine are two years old and I had to put one back in as I have a bulb crack and it is still brighter and whiter than the new bulbs
