The difference between LED and HPS! LED vs HPS. A "complete" starter guide
Growing with LED is incredibly versatile, because of the fast-moving innovations in this industry you can quickly become confused by all the different information you see. With this page we want to provide additional clarification of all the extensive information that can be found.
But what techniques are there actually: LED vs HPS
You will always find a number of terms close to each other, you have probably heard of the term HPS (High Pressure Sodium) in your search for the ultimate LED. These techniques have been known for years as the method of indoor growing, but based on results from the same wattage LEDs, these techniques are lagging behind. The difference between LED and HPS has become immediately visible due to the flow of information on the internet, which allows us to directly observe fellow hobbyists. LED is winning , and LED is continuously innovating, the HPS has been developed for more than 50 years and is virtually further developed. In addition, the investment that must be made in advance for the LED outweigh the disadvantages of the HPS. With HPS it is sometimes even advised to replace your HPS bulb after every cultivation, which ensures that you will be able to use it after your first Growing costs are cheaper with your LED system than with comparable HPS systems.
LED (Light Emitting Diode):
LED stands for Light Emitting Diode and is a type of lighting technology. LED diodes produce light up to 90% more efficiently than previous incandescent techniques! They work by using electronic voltage that passes through a microchip, which causes the small light sources we call LEDs to create visible light. To ensure that the LEDs can always continue to work optimally, the heat is absorbed and distributed by the heat sink.
By creating light as efficiently as possible, this ensures that the LEDs can work indefinitely, they will not burn out or cause defects in the diodes. Instead, the LEDs will lose lumens over time, causing the intensity of the light to slowly decrease over time. On the other hand, the lifespan of the diodes is tested at 50,000 burning hours , which equates to 3 years of running the LED completely every day, 24/7.
The LEDs have been so well incorporated into everyday life that we use them every day , so the TVs but also your telephone are part of this LED industry and it is used daily to illuminate life. With their small size, these diodes provide unique possibilities that are limited to our imagination! It is not without reason that LED has been the world's fastest growing market since 2000!
Because the Heat Sink absorbs the heat, you have the unique experience of growing in a growing environment in pleasant, continuous perfect conditions. Because the heat is absorbed, this ensures that LEDs do not overheat and can therefore last longer. This Thermal Management ensures that the biggest factor of success with LEDs is: the lifespan!
HPS (High Pressure Sodium):
HPS stands for High Pressure Sodium and is a type of lighting technology that was developed in 1968 as an energy-efficient outdoor light for industrial purposes and was mainly used in street lighting. In an HPS, light is created by means of high pressure in a compact tube with the gases Mercury, Xenon and Sodium in combination with the arc reactor. The xenon gas is easily ionized , which facilitates the arc reactor to create a spark when voltage is applied to the electrodes. The heat this generates causes the mercury and sodium to evaporate. The mercury vapor provides the increased pressure and keeps the voltage constant, and the sodium produces light when the pressure of the tube is high enough. HPS has approximately a white-light percentage of 29% of the energy used.
So in short: there is gas in the glass bulb, this gas is converted into light by pressure, this light is what you see when you turn on the lamp.
The disadvantages of HPS:
An awful lot of heat . The heat emitted from an HPS is significantly greater than that of comparable LED lights. The chemical reaction that occurs in the lamp ensures that a lot of heat is generated. If you don't know much about cultivation, you will find that temperatures will quickly become too high and uncontrollable without providing extra ventilation. This ensures that you always need an extra product to cool it when purchasing your HPS.
3x higher power consumption compared to LED. The power consumption compared to results is 3x as high as with LED, you will notice that a 600W HPS is comparable to the yields of a 200W LED , but it is often the case that if you grow with the same amount of wattage from HPS or LED you will get LED You have 3x higher yield compared to the HPS.
Requires a decent understanding of LIGHT and ENVIRONMENTAL FACTORS. When you start cultivating you will notice that the HPS will be too difficult an option, the threshold is often a lot higher because you have to take a lot more into account.
If you drop it there is immediate danger! This goes without saying, the tube is filled with gas, when it breaks the gas escapes. This can have direct consequences for you, your hobby and your environment!
LED vs HPS
It has become clear with the information obtained that LED is winning, the disadvantages of the LED no longer outweigh the advantages of the HPS. The HPS is becoming the more expensive variant, where you have to replace your bulb every time, which is a lot cheaper compared to LED.
If you grow/cultivate/cultivate for your hobby, it is best to use LED light. The ease of use and quality of LED + the cheap prices that we can offer together with our brands ensures that LED is the future!
