How do LED grow lights compared to HPS grow lights?

Light is the most important element in plant growth. The quality of light affects plant growth, flowering and fruit bearing. Growers stimulate photosynthesis at all stages of growth by providing specific wavelengths of visible light energy, using artificial grow light to simulate indoor sunlight.

Light is energy that can be separated into different wavelengths. Different wavelengths have different effects on life forms – different types of grow light are needed at different stages of plant growth.

For example, blue light promotes plant growth, while red light promotes germination or flowering. White light contains all the necessary wavelengths of the visible spectrum, so it can be used throughout the growth cycle. Most importantly, you need to ensure that your plants are provided with the right amount of light at any particular stage to ensure their health and growth as soon as possible.

Grow lamp is an artificial grow light source used to stimulate plant growth by emitting electromagnetic light (or spectrum) that is conducive to the process of plant photosynthesis. Plant growth usually requires photosynthesis, which is the process by which plants convert light energy usually from the sun into chemical energy that can be used to provide fuel for organisms. So basically, the grow lamp is an artificial light, which is used to provide the light needed for your plant to grow. In recent years, there has been a heated debate between LED grow light and HPS plant grow lamp. However, with the new progress of plant grow lamp technology, led plant grow light becomes more and more powerful. They are still more efficient than standard HPS or MH grow lamps. In recent years, the initial cost of LED grow lamps has decreased significantly, the technology has been improved to make better use of light science, and manufacturers recognize the energy-saving potential of LED grow lamps.

In the past, many indoor gardeners were cautious about the choice of LED grow lighting because they had experienced different versions of LED grow lights. But today, even long-term growers have decided to switch from HPS grow lights settings to more technologically advanced LED grow lights options

HPS (high pressure sodium) grow lamp is an electrical equipment using special metal halide and high pressure sodium grow lamp. They are famous for their efficiency when growing marijuana indoors.

Because of their energy-saving characteristics, these grow lamps HPS can also be found in street lamps. Although these lamps generate more heat than other forms of growth lighting, they are still popular with growers who want to effectively grow vegetables, fruits, flowers and even weeds indoors.

High pressure sodium (HPS) grow lamps contain additional elements, such as mercury, and produce a dark pink glow when first lit. As it increases, the pink orange light will warm into orange light. Due to the wide color temperature spectrum, HPS lamp is favored by indoor gardeners. Not only have they been able to grow flowers and lanterns effectively for decades.

Led stands for “light emitting diode”. LED grow lamps are more efficient than other forms of traditional gardening grow lamps. As a result, they generate less heat and have a long lifespan, saving growers a lot of energy costs over time. The biggest advantage of led grow lights over traditional grow lighting is how much energy it saves for growers. The photosynthetic effective radiation (PAR) produced by a single watt equivalent LED grow light source is roughly the same as that of 1 W metal halide lighting, but only consumes 0.1 W of power. Very power-saving. And LEDs produce a specific type of light that is most beneficial to cannabis plants,

First, we must understand the advantages and disadvantages of HPS grow lights and led grow lights before we can compare them;

Advantages of HPS grow Lamp:

HPS grow lamps are more standardized, making it easier to compare stores.

Lower initial cost of HPS grow lights starting device

HPS grow light bulbs provide a large amount of original light intensity, so they can produce high output.

Disadvantages of HPS grow Lamp:

HPS lamps use more power to generate light than similar LED plant grow lamps, and the efficiency is low.

HPS lamps also generate more heat than LEDs, which usually requires additional ventilation to maintain the growth chamber temperature.

Short lifespan time, the strength of HPS planting grow light bulbs will decrease over time and must be replaced approximately every 12-18 months, resulting in additional operating costs.

Advantages of LED plant grow lamp

Energy saving and high efficiency.

The temperature is low. LED technology is developing every year. A significant difference is that the operating temperature of LED plant growth lamp is much lower than that of HPS lighting.

Simple installation and long service life, which is basically twice that of HPS.

Disadvantages of LED plant lamp

At present, the initial cost of led growth lamp is high, but due to the low operating cost, it can save costs in the long run.

Generally; LED and HPS are mainly compared from the following aspects;

1 – Electricity charge

2 – Efficiency

3 – Service life (Lifespan time)

4- Spectrum, that is, the technical improvement in optical science

5 – Temperature of growing space

6 – Yield
