- Brand: Panasonic - Model Name: Twin Paluk Premier 100-watt - Color: Natural - Lifespan: 20,000 hours I bought this fluorescent light to replace one, but the main unit broke after about a month of use, so I stopped using it. I've attached the receipt in the image. My family works during the day. Since it was used for a short period of time, are there any Paluk users who would be interested? There may be minor scratches. Thank you for your understanding. I will reinforce it with the original box + bubble wrap + waterproofing + cardboard for shipping. Thank you for looking.
