Hello all, facing a very specific light bulb situation and curious if anyone has figured out a solution for something similar. We're shooting in a hallway with practical ceiling units lining down the center of the hallway. This isn't necessarily that big of a problem if the camera just stayed in the hallway as I could just color correct the green out in post, except for the fact the the camera will follow talent from the hallway into their apartment in many scenes which is illuminated by big windows of daylight. The disparity of the CFL's and the clean daylight make the hallway look garish and aweful so I'm trying to figure out a way to clean up the light quality. The CFL's in particular are GX23-2 2pin base. They do not except adapters to medium base. They do not except high wattage CFLs to overexpose a little and clean up the colors a bit. They are outputting so little at 13w that wrapping them in gel will kill most the output. The director wants to see the symmetry of them in the ceiling as we walk the hallways so we can't turn them off and just illuminate from the other end of the hallway. Is there any other "tricks" any of you have found that might address this issue?

You can do a color grade ramp in post as you move in and out of the hallway. A little tricky, but possible.

Can the ballasts handle hire wattage bulbs like these   http://1000bulbs.com...8-FDL28EXD.html ?

 

These bulbs are 5000k  and will better match the windows.  PLus, adding 1/8 -green will correct the color enough without killing all the output.

It should be easy enough to remove the green cast in post without affecting the daylight scenes.
