i've been searching the forums to get an idea of how to shorten a 48" fluorescent fixture to 24" and how to overdrive it, but i couldn't find an exact description of what i wanted to do. i was hoping someone could help.
i would like to get a 48" 4 lamp fixture and shorten it to 24". this seems like if i just cut out 24" of the reflector and used the existing ends with 4 24" bulbs it would work without a problem because the ballast would "know" what kind of lamp is in it. please correct if i am wrong here.
next, i would like to overdrive the 4 lamps by getting another 4 lamp ballast so that with the first ballast i could overdrive 2 lamps, and with the second ballast i could overdrive the remaining 2. the venerable zink had posted that this was possible by wiring 2 of the lamps end to end in series. however, being that i'm not exactly sure on how to do this i was hoping someone could help with some detailed instruction.
what i thought might be correct was to wire the ballast ends of the 2 lamps together and then connect the ballast end of one lamp to the ballast. then to wire the other ends to each other, and wire one of those to the "yellow wire" or the non ballast connection.
but....
that sounded like parallel to me.
is the correct configuration this:? wire the ballast end of lamp1 to the ballast, then the non-ballast end of lamp1 to the ballast end of lamp2, then the non-ballast end of lamp2 to the the non-ballast end of the ballast?
sorry if this is confusing, but i'm confused myself. any help is much appreciated. and a diagram would be awesome :)
