Mh bulbs help please


#1

Hi just a quick one do mh bulbs have starters built in the bulb walked in one light was just flickering with a pinging noise

Is this a system that had been running fine for a while or relatively new? I’ve seen something like that happen with with a 230 volt ballast wired up to 120 volt source. Not in a grow, but I work with some real special people lol.


#3

Yes everything was fine to now


#4

Hopefully its just the bulb. Mh last around 1000 hours, otherwise it might be the ballast


#5

@Laurap would the buld cone back on because I switched it of and on its came on and stayed on

Just watch real close. You dont want an electrical fire. Sounds like bulb though. Theyre only about $12 on amazon.
