Cabinet Retrofit

[mbarden]

Hi Folks,

Bidding our first retrofit from magnetic ballast T12 lamps to electrinic ballast with T8 lamps. My question to you fine folks is this,...... my distributor offers T8 sockets from France in what appears to be 2 configurations: a "Marker" type and a "Bullseye" type. Both types have both the fixed end and the spring end. Which one would be used for a retrofit and will I have to replace the socket raceways?

Thanks

Should not have to replace the raceways; they are made to fit in the same D-hole. As to which configuration, depends on if they were markers or bullseyes to start with...

Be aware the wiring is likely different so you aren't gonna replace just the sockets, but probably rewire the whole thing.

OK, Heres a dumb question that I should know. What is the differnce between marker and bullseye. I am realtively new and have only worked with and replaced kulka lamp holders. The kind that after punching the D hole you just snap them in. I have worked with some tombstone style as well.

BTW thanks for the response Eric. Was just reading a little about Blair Companies in one of the latest mags during a morning "office" visit.

Bullseye has the lamp perpendicular to the raceway cover. Marker is "Tombstone", so the lamp is parallel to the plane of the cover.

I believe the marker socket replaces the tombstone socket in intermediate wireway applications. So depending on what type of sign you are retro fitting, single face over 10' with intermediate wireways will use both the marker and bullseye and double face will use the bullseye only. Both come with the "D" shaped back, so you should be able to use the existing wireway covers.

Thanks Mike,

(2) Signs. Both are under 10' in length. (1) 5' x 3'h and (1) 8' x 4'h. Both are double face.

Appreciate the info and help Mike, take care.

What to use shouldn't be that big of a deal if you look inside the cab you are retro fitting (which you should be!)

Agree Brian,

Am trying to avoid having to go onsite a secong time to catch a few things. Looks like I am going to go back to check more out.

Thanks for the help.

Why are you replacing the sockets? The T8HO have RDC bases
