New 18-watt fluorescent bulbs. Phillip’s brand, 110 Volt, part # PL-C. Overall length is 6 ½”x, 1 3/8” diameter. Bulb length is 5” These are a cluster of four (4) bulbs with a two-pin connector. I’m not positive, but I believe these were used in continuous-on applications such as exit signs. Ten (10) bulbs in their original boxes. Sorry no payment Apps, cash only. No offers, I think it is a fair price. If the ad is posted I still have it. I take down my ads as soon as items go out the gate. Thanks for looking.
