The biggest advantage is when running vertical, all the heat is produced on the socket side and the other end is relatively cool. They also produce a lot more lumens than t8's and more than t5's from the ones I compared. A workhorse 8 can easily run 3 of the 55w and 4 of the 50w. They lose a lot less light internally than cfls.
Yeah I have open wiring in my cab at the moment too :/ Needing to get 18 gauge single strand, since the multi strand doesn't work on the 2g11 sockets worth a darn. And I hate electrical tape. I'm not sure what I'm doing wrong but can't get electrical tape to stick worth a darn even when brand new.
