Thanks for the headsup! Those look like the Welthink ballasts which have, as far as I can tell, horrendous reviews. I decided to go with a standard Phillips 220V ballast + a step down transformer. Wish me luck!
Our Grobal 315w Ceramic Metal Halides...Full Spectrum t12 philips elite agro(only CMH made for horticulture) with 4year bulb life..All products UL/ETL listed...Large increase in yeilds, resin production, terps and flavornoids...Best balance of UV-A-B-C noticing the UV-C is helping significantly with people having mold and PM problems, Highest PAR per watt bulb on the market today with incredible light penetration...Our hoods are the only purposed build using CAD software and an electrical engineer for the 315w CMH on the market, unvented and unsheilded because the bulbs run so cool resulting cutting cooling on commercial grows in half therefore significantly decreasing power consumption and not having light loss due to dirty lenses...The ballast are low frequency digital ballast (plug n play) that run at less than 1.4amps and use 240V OR 120V plugs...Also we don't know why yet as we have some leads but "we" in the CMH community have been noticing a significant decrease in flower time...55-60 day strains coming down in 42-45 day...65-70 day finishing in 52-55 and I mean FINISHED resulting in extra harvests a year...So higher yeilds, resin, terp, and flavornoid production, with decrease power consumption and decreased flower time...Sounds to good to be true I know...For example we just fitted one of the top dispensaries here in Colorado with 24 of our 315w CMH's(7,560w) in place of 8 1000w's...On their run (designer strains) with our new setup they increased their yeilds buy 10+ pounds with NO Co2!!! Cut their cooling in half and harevested the crop over 10 days earlier...Since then we have built out 5 more rooms 2 rooms were fitted with 24 lights that had 8 1000w as well then 3 new rooms with 30+ lightss...Their harvest/numbers are all MMED verified...These lights are great for growing great hash making buds so I have been reaching out to many hash makers...Hit me with any questions or if you are looking for proof...So yes they can run 120V
