they work fine on a standard M57 ballast and give a higher PPFD and better colour performance than on an electronic ballast.

dude if you wanna blow your dough on ushios only to find out that if and when they fire your water looks like lemonaid, power to you. retailers won't return them. if you don't belive me call j&l and tell then what brand of ballast you have and see what they say.
