guys
I face some problem while i am DIY my 250w mh today
i am using a magnetic ballest with Radium bulb it cant seem to fire up. However there is a bUzzzzing sound around the ballast.
i began to suspect that my wiring is wrong ... but cant be as i had follow the wiring of a 150MH which is also DIY.
The only problem that i can think of is can a Radium bulb fire up by a magnetic ballast ? As i heard before that some bulb cannot be fire up by magnetic ballast.
Can any Radium bulb user let me know what kind of ballast u guys using ?
