Not all bulbs work with all ballasts... I have read the Ushio and Kolorchrom (Geissmen), are both German made bulbs and have the best compatibility.

do you think its worth upgrading ballasts? or would it be better to buy a higher quality fixture for the long run? my birthday is comming up so i might ask for some gift certificates lol
