The data that are reported about grow lights are often misleading.
Manufacturers use metrics like "advertised Watts" and "HPS equivalents", which are little more
than marketing gimmicks. Even when they publish figures for Photosynthetically Active Radiation
(PAR) or Photosynthetic Photon Flux (PPF), it can be tough to know if the data is a measurement or
a calculation, and what they really mean. There are allmost no good standards in the industry that
allow us growers to make accurate comparisons between different fixtures.
We, at ECOLED, conduct FIELD TESTING in a suitable grow area which the fixture is designed for.
Displaying the most relevant metrics, how a fixture will perform in a grow space.
We only use the data of USABLE PPF, because it's the only metric that really matters for us growers.
Our Fieldtesting is fair and conducted above a crop or nonreflective floor.
