I put new Hamilton 10k bulbs in at the beginning of May. I have 4 x 250w lights, 2 x 4 foot Hamilton Cebu Sub fixtures.
Three have failed now. One failed after a week and was replaced by Hamilton. 2 Failed today, one in each Cebu sun.
I was a set ahead because I got 4 from Marine Depot on clearance so I have 2 more in the cabinet.
Anybody got a suggestion for something else to try? 250w mogul base. I run electronic M58 ballasts.
