A Tiffen 4x6" FL-B filter is used to correct the color balance when shooting tungsten film under fluorescent lighting.

An FL-W filter is used to balance daylight film under warm white or white type fluorescent lamps. Tiffen FL-D filter is used when you wish to correct for the greenish tone that appears when shooting daylight film under general purpose fluorescent lighting. 

Fluorescent lamps burn at many different temperatures and often require more demanding filtration for exact results. For specific filtration and professional use, it is strongly recommended that a color temperature meter be employed along with Color Correction filters (i.e.CC30M) when shooting under fluorescent lighting. This is the only proven way to achieve exact color correction.
