This is a set of two, almost-unused, circular fluorescent light bulbs (one each of ① and ②). (Please see "Additional Notes" for the reason they are almost unused.) ① A circular fluorescent light bulb that emits natural light and has a lifespan of approximately 20,000 hours. - Brand: Panasonic - Model Name: Palook - Light Color: Natural light - Shape: 40-watt - Lifespan: Approximately 20,000 hours - Power Consumption: 38 watts - Size: Circular ※ Additional Notes: I bought the wrong ones, so I'm selling them. I opened the package and installed one, but then realized it was the wrong type, so I'm describing them as almost unused. ② A circular fluorescent light bulb with a lifespan of approximately 6,000 hours, emitting a clear, refreshing, three-wavelength daylight. - Brand: Panasonic - Model Name: Palook e-Day - Light Color: Three-wavelength daylight (cool color) - Shape: 30-watt - Lifespan: Approximately 6,000 hours - Power Consumption: 28 watts - Size: Circular ※ Additional Notes: The package in the photo says it's a set of two, but I am selling only one. I used one, and I am selling the remaining unused one. Thank you for viewing.
