Review on 💡 Energy-Efficient Ciata Lighting 13 Watt Compact Fluorescent: Illuminate with Eco-Friendly Brilliance by Matt Watson

I have them on photosensitive switches and the first one blew out in less than 10 months. If the average darkness is 12 hours per day, that's a total of 3600 hours. Marketing claims their average lifespan is 10,000 hours. Pretty disappointing, like all lightbulbs these days.
