One 48" T12 fluorescent light bulb (EFC/Westover (N. Arlington))

Roughly 10 years old but never used (but not tested). GE Ecolux Wattmiser F34CW-RS-WM-ECO "Good to Have" replacement if you are using this same bulb or anything similar. Obviously also good for any other 48 inch fluorescent fixture if you don't mind (or prefer) bulbs with different tints, like in a garage or laundry room.
