Email them, someone was quoted over $500 for the 315w kit if I remember correctly, prices change though.......It's not cheap due to all the safety features on the ballast plus increased lumen per watt/
95% lumen retention at 25,000hrs, that's a big boost and puts it in led/induction league IMO. AND very high efficiency,
ballast consuming only 16w to power 315w bulb . IF you believe it
the cycloptics greenbeam is around 700 using the cerametek ballast, but that kit comes with their own pricey vert reflector
The 375w ceramatek kit , you definitely wanna go with the 840 bud p bulb(vert 45+- position only)
tell us what they quote you on them............and ask if 120v input is accepted to the ballast??? i'm not sure
good luck
