Review on 💡 Counter Industrial Electrical Pack F8T5 CW Fluorescent - Efficient Lighting Solution by Lauralee Jensen

Used in an aquarium. We bought six on January 30, 2018. The last one was delivered today, September 10th, 2020. The light is designed for 12 hours a day. The packaging states that the average lamp life is 5000 hours. At 12 hours a day, they should each last 417 days. The six bulbs I bought should last almost seven years. Instead, the five lightbulbs lasted 954 days, or about 191 days each. They lasted less than half the time stated.
