This is a set of two Panasonic Twin Palook Premier 100W (Warm Color) double-ring fluorescent light bulbs. These are being sold because they are no longer needed due to a lighting fixture malfunction. 【Product Details】 • Manufacturer: Panasonic • Model Number: FHD100EL/L CF3 • Light Color: Warm Color • Rated Life: 20,000 hours 【Set Contents and Condition】 This is a set of 2 bulbs in different conditions. Please be sure to check the following: 1. Unused (1 bulb) Purchased on December 5, 2025. Opened once for replacement, but not used because the fixture was found to be faulty. It has not been powered on and is in new condition. 2. Used (1 bulb) Purchased on February 27, 2025. Used for approximately 10 months. It was working normally until removed. * Initially, I didn't realize the fixture was broken and was going to discard the bulb, so "HAIKI" (disposal) is written on the outer box with a marker. There is no impact on the contents, but please be aware of this before purchasing. (See image 7) 【Shipping】 Each bulb will be placed in its original box and carefully protected with cushioning material before shipping. Fragile items will be packed securely. The shipping method may be changed from Yu-Yu Mercari Bin ↔︎ Raku-Raku Mercari Bin. Please understand. 【Important Notes】 • Please use with "High-Frequency Lighting Dedicated (FHD Dedicated)" fixtures. • Please purchase with the understanding that one bulb is used and the box has "HAIKI" written on it with a marker. The price is cheaper than selling them separately due to shipping costs. If you are looking for spares, how about these?
