Understanding and optimising LED efficiency saves hundreds of euros in electricity costs in the long term. Efficiency calculation and optimisation.
LED efficiency is crucial for profitable cannabis cultivation and low electricity costs:
Understanding efficiency - μmol/J explained:*What does μmol/J mean?
Efficiency is measured in lumens per watt (lm/W). Divide the total number of lumens produced by the wattage of the LED bulb to determine its efficiency.
The best options are full-spectrum LEDs with high PAR output and an efficiency of at least 2.0 µmol/J. Brands such as Samsung and Cree often deliver the best results.
Use timers to turn on the lights only during the growth phases, and make sure the lamps are positioned at the optimal height above the plants to minimize light loss.
