Long-life 20,000-hour warm-toned 85W fluorescent light, perfect for home use. - Brand: Panasonic - Model Name: Twin Parruc Premier - Color: Warm Tone - Shape: 85W - Features: Long life of 20,000 hours - Application: Home lighting Thank you for viewing! I bought this because the light wouldn't turn on, but it turned out the problem was with the fixture itself, not the fluorescent bulb. So, this fluorescent bulb is no longer needed. Since fluorescent lights will be discontinued in a few years, it might be a good idea to stock up! I did install it in a fixture once, so it is considered a used item.
