Calculating the BTU Heat Load of a Fixture

When determining the heat load of any Creamsource fixture, it is important to remember that all of the power consumed by the fixture in a closed space will be converted into heat. Therefore, it is essential to have appropriate cooling systems in place.

For any lighting fixture, the standard formula for calculating BTU/hr (British Thermal Units per hour) is Watts multiplied by 3.412.

Using this formula, you can calculate the total heat output of a fixture. For example, a Vortex4 fixture has a power rating of 325W. At maximum power (100%), it would generate 1109 BTU/hr of heat.
