I don't know about the brand, but 14K bulbs are pretty blue depending on brand. A 10K bulb will be yellower but if supplimented with PC, VHO or T5 actinics you will have a much brighter tank that will be a nice crisp white look. I replaced 4X96 watt PC's with 3X150 watt 14K HQI's and my tank look really blue and not near as bright. After I replaced the 14K HQI's with 10K's the tank looked a whole lot brighter but I did add some VHO actinics and the tank looks awesome.
