One of the hurdles that LED growers face is trying to equate their new, efficient lighting to systems and theories that were developed under traditional light sources. LED ljusskyltarat grow lights have very little in common with the sun, high pressure sodium, or fluorescent lighting. This misunderstanding has been amplified over the last two years by LED plant lighting companies marketing arrays using product descriptions such as "replaces 400 watts of HPS." This kind of statement is incredibly misleading and implies one can simply switch out an HPS with an LED array and expect the same results regardless of the application.

The rhetoric has become so popular that growers have come to expect manufacturers to rate their led grow lights in the number of watts of HPS they replace. The fact is there is no scientific basis for a direct comparison to HPS. This isn't to say you can't replace HPS with LEDs- just that they are two completely different light sources with their own measurement variables and characteristics. Simply switching out the lighting systems will not give the same results. On that note, commercial growers, scientists, and educators basing their projects or utilizing methods developed through research under HPS or fluorescent lighting, should expect different results under LEDs ljusskyltarat .

The difference with the most profound effect would be temperature. The majority of research available on the effects of manipulating photoperiod or light intensity is based on a radiant (hot) light source such as HPS or the sun. Up to 80% of the light emitted from an HPS lamp is emitted as heat. With this in mind, HPS studies are not only manipulating the light, but manipulating temperature within the plant canopy. If you replace an HPS with a well made LED array you are able to provide more quality wavelengths but you have also eliminated the radiant heat by removing the HPS. It stands to reason that the outcome will not be the same.
