Circular fluorescent light with a natural light and a lifespan of 20,000 hours. - Brand: Panasonic - Model Name: Twin Parruc Premier 100-watt - Color Temperature: Natural - Lifespan: 20,000 hours - Shape: Circular Thank you for viewing. I purchased this at the end of the year and used it for about a day, but the original ceiling light itself broke, and I switched to an LED type. Therefore, I no longer use it, so I am selling it.
