Breaking the Famous Myths about LED Grow Lights
LED grow lights are often associated with negative myths because many people do not consider them a powerful option when looking to achieve higher yields. The problems are often present because of manufacturers that produce low-quality products which are often the actual problem. Here, we present some famous myths that are prevalent in the market about LED grow lights. We will ensure that we break each myth by showing that good quality products do not have such issues.
Myth 1: Low Efficiency
This is a common myth where people believe that most of the power supplied to a LED grow light is lost as heat and the device actually uses less than half the supplied power. The above point may be true for most LEDs, but the issue is that the ability to use half of the energy supply is a great improvement when compared to the other available systems.
LEDs are so much efficient that it only takes a 600W LED to replace an existing 1000W HPS light. This means that modern LED grow lights can offer as much as 40% savings in terms of the electricity employed in the light. For a moderate grow application, these savings amount a huge sum over the course of the year.
This is one myth that is certainly not true as LED lights are among the most efficient passive electronic devices in the world.
Myth 2: Lower Yield
A very important myth is that LED grow lights offer lower yields when compared with the performance achieved with HPS and HID technologies. The problem is that it is the experience of many people that they get a lower yield when they an LED. This actually occurs because they buy cheap LED lights from low-quality vendors.
LED lights have the same yield potential when compared with other technologies if you buy them from a reputed manufacturer. These lights can show even greater potential when they are installed with their complete optical system. This optical system is able to concentrate the photons so that they can penetrate the canopy in an efficient manner.
If you look closely at the technical parameters of the available LED grow lights then you can easily select the models that have the same yield numbers as available with lamps based on other technologies. Another amazing aspect is the improved quality of the yield. The use of LED lights not only increases the yield, but it also ensures that high-quality product is achieved.
Myth 3: Heat Management
Heat management is essential with LED lights as they work best when they are at a lower temperature. Many grow systems require a heat management system such as a fan to remove the hot air from the area to ensure that the LED can work at its maximum efficiency. The requirement of additional equipment often raises the prices of the existing systems.
Although it is true that heat management is required with LED grow lights, but they are still much better than HPS lights in this matter. They do not produce as much heat as produced by other methods, thanks to their lower power values.
Good heat management, however, can improve the performance of the LED so much that it is essential to place a heat extraction system. Such a system keeps the LED lights functioning at their best efficiencies, therefore producing the best results in a horticultural environment.
Myth 4: LED Lights are Expensive
This is also a famous myth that LED grow lights are expensive when compared with other systems that provide the same yield. It is true that the cost of LED lights is higher when compared with HID lamps, but you need to put the perspective of return on investment here. LEDs also have a much longer lifespan when compared with rival technologies.
You need to understand that as a commercial grower, you require a long term solution on which you can depend completely season after season. When compared with the higher energy costs of the other systems, the installation of LED lights provides a much better return on investment. The system has a great life of at least 50,000 working hours, which is greater than other available systems of comparison.
LED grow lights also require smaller support systems because they do not produce as much heat as produced by some other systems. They are reliable, accurate and function effectively in all horticultural applications.
Myth 5: Shorter Lifespan
Many people argue that manufacturers often mention the wrong lifespan for their LED products and LEDs often fail before reaching that time. They argue that people do not understand how LED lights can fail when the temperature is not managed properly and therefore degrade in performance in a quicker fashion when compared with other available choices.
This myth, however, is totally wrong and baseless. LED grow lights at least have a lifespan of 50,000 working hours and good quality products are often rated to fail at 100,000 hours of use. This is much greater than the typical life span of 20,000 hours of use for other lighting options used in the grow industry.
Another important property is the reliability of LED lights. They do not degrade light filament bulbs which often lose a great portion of their light after they have been used for six to nine months. LED lights lose that same amount after they have been used for a number of years. This ensures that they can be reliably installed for longer periods and growers can trust them to produce the perfect results.
Myth 6: LED Grow Lights are Hard to Maintain
LED lights often come as a complete installation system with their small heat extraction unit and attached the power supply. People argue that these systems often fail and require replacements. The argument, in fact, is true because these people buy LED lights from cheap vendors that do not sell the right supporting systems for LEDs.
LED grow lights actually have a very long life. The supporting units for these lights, therefore, have to be at least as sturdy as these lights. High-quality manufacturers, therefore, provide heat extraction systems that can also last around 100,000 hours of use because good LED grow lights can often survive this long and require support.
These are a few of the common myths around LED lights used in horticulture. Most of them are based on rumors and rely on the information available from poor quality manufacturers.
