Hi in another thread someone who answered my question got me thinking and i just had a look at my ballast and all it says on them is sodium/hailide
so which bulbs can i use in them ?
i dont want to go burning my house down
cheers Bifter
Rob you are a star ,the ballasts are all 400w and i have 3 son-t plus 2 sodium hailide and 1 mh
so are you saying i can use any of them in the ballasts?
thanks again Bifter
