The most important point to compare output of led lights
The Watts Drawn
True Watts Drawn (Actual Consumption) is the most imporant measurement frequently cited by LED light companies.
What Do Watts Measure In LED Lights? (led grow lights, led flood lights, led solar lights)
Watts drawn measures energy consumption, not output. They tell us how much energy a light requires.
How To Understand Wattage And Its Correlation To Efficiency
If the efficiency and the output of the lights are not determined by the wattage, then how are they determined? Starting with the quality of the components and materials and going through the actual design (fans, heat sinks, chip density). There could even exist a reverse correlation and the lights that require more watts could be less efficient. In other words, if a LED grow light company is boasting about its wattage, you need to keep in mind this might be misleading and you should possibly research further.
