Climate, Cold & Container GrowingHow is horticultural lighting efficacy different from a lamp's electrical wattage?
Efficacy relates useful photon output to electricity consumed; wattage alone describes electrical demand. Compare fixture specifications on the same basis and distinguish emitted photons from light actually reaching the mango canopy. A low-power unit is not necessarily efficient, and an efficient unit may still be poorly positioned. Evaluate output, delivery, and operating cost together.
