Disclaimer - The numbers used to create this caclulator were inferred from commonly used specification sheets. In some cases, the actual input wattage of a fixture differs from the listed wattage due to the ballast or driver. This calculator takes into account those differences and uses a corrected wattage. Due to the varying nature of projects, this caclulator can be used for estimation purposes only and holds no legal weight. A electrical engineer should be consulted if certified data is needed. The reccomended replacements are recommendations only. Every fixture should be evaluated by a professional to determine the suitable replacement.
