Amount of wattage?

[Wilty]

OK! I understand now!!!!!

I was working backward since I can get the ballast cheap and I am hoping to match a bulb to the ballast. The ballast runs M59 I believe, off memory. I don't have bulbs yet, just ballasts and I haven't wired them yet. I may find I can't get bulbs for the ballast. I found out the bulbs the supplier sells with this ballast are 4700K Phillips. So. . . not so hot

I will see what the LFS has in the way of bulbs to give me an idea.
