8-ft LED wraparound lights typically consume between 40 to 80 watts, depending on the model and brightness. In contrast, 8-ft fluorescent lights, such as T12 or T8 tubes, generally consume between 75 to 110 watts per tube. Assuming a direct comparison where both LED and fluorescent fixtures provide similar light output, the energy savings can be significant.
For example, if an 8-ft LED fixture uses 60 watts and replaces a fluorescent fixture using 110 watts, the energy savings per fixture is 50 watts. Over time, this difference accumulates. If the lights operate for 10 hours a day, the daily energy savings per fixture is 0.5 kWh (50 watts x 10 hours / 1000). Over a year, this amounts to approximately 182.5 kWh saved per fixture (0.5 kWh x 365 days).
In terms of cost savings, assuming an average electricity rate of $0.12 per kWh, the annual savings per fixture would be about $21.90 (182.5 kWh x $0.12). If multiple fixtures are used, the savings multiply accordingly.
Additionally, LEDs have a longer lifespan, often lasting 50,000 hours or more compared to 15,000 to 20,000 hours for fluorescents. This reduces replacement costs and maintenance frequency, further enhancing cost-effectiveness.
Overall, switching from fluorescent to LED wraparound lights can result in substantial energy and cost savings, along with environmental benefits due to reduced energy consumption.
