hi all, i have 2 6000watt ballests CENTURY 220/230 volts uk plug with hps bulbs running and on the caseing it says SON T NAV T
what does this mean????
does it mean i could run either hps or mh, anyone help me out please
 
6000w or 600 is it a mag. and coil ballast maybe post some pics! is it new or old is it from a lamp post or construction equip. im guessing you tried a google search?
 
i am not 100% sure but through the quick research i did something about the ignitor inside the bulb or out side for instance my balast only take lu bulbs and some otheres are just l. i am trying to find a discription for them but can t! i guess thats why u asking here
