One of the barriers to collaboration with producers is to test the equivalent of their new efficient lighting systems and theories developed under the traditional light source. The direction of light is very low in the sun, high-pressure sodium or fluorescent lighting. This disagreement has been raised over the last two years by LED lights companies that use companies with product descriptions such as “Replace 400 HPS hats”. This type of statement is incredibly misleading and indicates that it cannot switch an HPS into an LED array and expect the same results regardless of the application.
The rhetoric has become popular as manufacturers are expected from manufacturers to gauge their lead consumption in the number of HPS watts they have replaced. The truth is not a scientific basis for direct comparison with HPS. It does not say that you can not replace HPS with LEDs – they are two completely different light sources with their own measurement variables and characteristics. Mobile lighting systems alone will not provide the same results. In this register, commercial producers, scientists, and educators based on their projects or the use of research-generated techniques under HPS or fluorescent lighting should expect LED results.
The difference in the deepest effect is the temperature.
Most of the available research on thе effects оf photoperiod manipulation or light intensity is based on a (hot) light source such as HPS or the sun. Up to 80% of the light released by the HPS lamp is pumped as heat. In this sense, HPS studies not only manipulate light but manipulate the canopy temperature of the plant. If you replace an HPS with a well-made LED array, you can provide better wavelengths, but you can also remove the heat source by removing the HPS. That’s why the result is not the same.
To illustrate this point, let’s look at the figures of a strawberry greenhouse in New Zealand where HPS turns on one side and LED Grow Master LED on the other. The greenhouse uses climate controls to control the temperature, but even with these controls in place, there is a big difference between HPS and LED temperatures. Mr. Kolovos said: “When the lights arrive (6:00 am), the area under the lights of the SPH is immediately brought back to room temperature, as this will not happen in the remaining greenhouse until 10:00 am. are kept under HPS fire until 21:00 when they are open while the temperature under the LED drops to 16 hours. “
Clearly, there is a significant difference between the two light sources.
LEDs do what they really want: to provide a light quality, with very little energy, with a lifespan 10 to 20 times longer than the traditional light source. In the case of the greenhouse above, the heat should be filled in the morning and evening at the edge of the LEDs because they are obliged to pay the heat emitted by HPS for all photoperiods. Environment better, cost-effective and user-friendly to add heat only when needed. This is a unique advantage for LED lights.
Finally, while a LED card is not “replaced” by an HPS such as Apple does not replace the orange, LEDs offer an excellent alternative. By accepting the natural differences between HPS and LED, we can overcome the confusion created by trying to incorporate LEDs into the HPS box, and start accepting LEDs with their own merits.
