70-watt fluorescent light bulbs with a cool color temperature and a lifespan of 16,000 hours. - Brand: Panasonic - Model Name: Twin Parruc Premier - Shape: 70-watt - Color Temperature: Cool Color - Lifespan: 16,000 hours Thank you for viewing. These are new and unused, but I purchased them as spares and they have been stored for several years. (One box is marked "old," but the contents are the same and new.) If you would like two boxes, I will relist them separately. Thank you.
