I have one that came on my finnex I THINK...I will have to check...I had problems with several and they said they had a bad batch so I have 3 new ones (different brand)
Of some that I sent back he said a couple seemed to work, so it might be worth a shot...If I have it, you can have it...I'll try to look tonight...How old are your lights??? What brand are your ballasts?
I sent them all back but I think I have one that didn't go back
