Do hydroponic Grow Lights (MH & HPS both) necessarily need a ballast or would they work without one?
ok im working on an all DIY and hand made experimental water culture system and im almost done with it except the lights and lighting related material and issues… now i know what i need if i was to purchase a final product from stores but i just needed to know if its possible (of course not with too much risk or problems, plz explain if u know of any) to use a mogul based grow light with a medium base converter directly without using a ballast or do i HAVE to use a ballast? I hope i made myself clear enough but let me know and i’ll add more details or clarify exactly what im taking about! Thx
Yes, you need a ballast for both MH and HPS bulbs. These lamps operate using a higher voltage for ignition of the gas and then the voltage drops down to an operating voltage. The ballast is necessary for the lamp to work.
