First time replacing the bulb on used grow lights I bought.
The current bulb is working
Went and bought a new bulb and it did not work doesnt light up at all and ballast just buzzes.
Went back to store and bought another bulb and it didnt work again but yet the original bulb still works and fires right up .
In the photo the bulb on the right is the new one
I have another 400w ballast same.type but newer and it worked fine replacing the bulbs .
This is an hps ballast and hps bulb I have triple checked all that the wattage is right these bulbs work in digital and magentic .
Only thing I can think of is this ballast is an older one older than the other 3 I have from.2003 any chance there were differnt type bulbs back then or soemthing weird like that ?
