Our Harvest Pro® ballast with dual input voltage easily switches from 120 to 240 volt power! Simply unplug detachable 8 foot 120 volt power cord (included), turn power plate around for 240 volt power and plug in a 240 volt power cord (240v power cord can be swamped out for 120v if desired). Dual universal lamp cord receptacle is compatible with all Sun System® brand reflectors as well as other branded reflectors. Louvered end plates and heat slots help cool the ballast for years of trouble-free use! Aluminum ballast enclosure is engineered to dissipate heat and keep components cool. Heavy duty handle for easy carrying or wall hanging. A barrier wall between ballast and the capacitor/ignitor helps keep the critical components cool. The capacitor and ignitor temperatures are greatly reduced by being separate from the ballast core. Lower temperatures mean better reliability & longer life. Uses high quality capacitor using German sourced film to ensures long lasting durability. EZ Cap® Door offers easy access to the capacitor in the event it needs to be replaced.
