I was telling Varun about installing a thermal fuse in-line with the power cord for my T5, it will be mounted on top of the grow rack Prior to installing a cooling fan this area got too hot to touch with my new 6 bulb t5 fixture, anyways here is cheap insurance in the unlikely event the fan stops

thought it may help someone else, hey... less then 2 bucks, cant beat that

60c thermal fuse
