What is efficacy?

The efficacy of a fixture can be determined when the lumen output is divided by the system power.  For example, if a fixture boasts 5000 lumens and has a wattage of 50, the efficacy would be 100 lumens per watt.  Our fixtures are industry leaders in efficacy, which can be as high as 170 lumens per watt.  With this kind of efficacy our customers are see up to 90% energy savings, which of course means a huge decrease to the cost they see for their monthly energy expense.
