Hi, need abit of help. i was just about to move onto my 3rd grow. went to turn on my 600W HPS and there was no life it, but a strange clicking sound coming from the ballast. so thinking the bulb was blown i put in a 400W light that i had. but now the light will come on for about 1min and then go off, then back on for a min. it will keep doing this. anyone any ideas
Yes - it's broken. Buy a new balast. The clicking is most likely the relay... either way, if the light dont lit - you must acquit!
