Philips F40T12/CW SUPREME 40 Watt Fluorescent Light Bulbs

10 bulbs. Some new, some partially used. Philips F40T12/CW SUPREME fluorescent light bulbs. Each bulb is 40 watts and designed for cool white light. They're from the Alto Collection and use Mercury. These are great for illuminating large spaces. We changed our basement lighting system and no longer need these. Some are still brand new.
