Maybe if Bryan is going to swing by I'll ride over with him. I'd like to check it out. Are you happy with the color? Why are you looking for 10K now? Have you considered the Iwasaki 175w 15k (very white with lot of PAR).
If you want to try the 175 out let me know, you can borrow bulb, and ballast, LIII reflector too if you need it, the bulbs are SE.
