This is a set of two Toshiba FL15SW/NL white fluorescent light bulbs. They are unused, but quite old, so I cannot guarantee their operation. There is some damage to the outer packaging at the ends, and some damage to the base as shown in the image, but overall, considering their age, I believe they are in extremely good condition. They are "Neo Line White Noise-less," which makes me wonder if they have a special purpose, but they should also be usable as ordinary 15W fluorescent light bulbs. I couldn't find any similar products even after researching, so I'm not sure if they are a rare item. I feel that they might be more valuable for collecting than for use... I think they are probably dead stock from over half a century ago, so how about it if you need them?? (Tokyo Shibaura Electric Co., Ltd. → Toshiba Corporation changed in 1984, so before that) - Brand: Tokyo Shibaura Electric, Toshiba (Current: Toshiba, TOSHIBA) - Model: FL15S-W/NL FL15S⋅W/NL - Quantity: Set of 2 - Color: White Thank you for viewing. I have many rare items in good condition related to tube lighting, and I will be listing them little by little...
