What is an LED Grow Light?

What is an LED Grow Light

LED (Light-Emitting Diode) Grow Light is a type of energy-efficient artificial light that is used to help indoor plants develop naturally by supplying them with appropriate lighting. The majority of LED lights emit blue and red light waves, which are responsible for plant growth. Phytochromes (responsible for leafy development) respond to red light waves, while blue light increases photosynthesis and generates stronger roots. Red, blue, or both light waves are required for optimal plant growth depending on the plant type.

Types of LED Grow Lights

Types of LED Grow Lights

LED grow lights come in a range of shapes and sizes. You can narrow down your options for an indoor garden by familiarizing yourself with the most common styles.


Spread-style LED lights feature a huge surface area covered by a large number of small individual lights, making them ideal for illuminating a big number of plants. Light spreaders come in two primary forms: spiders and quantum boards.

Vast numbers of tiny LEDs are spread out over a large, flat surface area in quantum board lights. As long as the LEDs are white and passive cooling is used, the plants can be placed directly beneath them without fear of overheating from excessive heat emission.

An open bar form, rather than a solid board, is used for many LEDs on narrow “arms” in spider-style lights. Compared to quantum board lights, these can be more expensive.

Chip on Board (COB)

This type of illumination is known as chip on board (COB) because it has a large number of small LEDs packed close together on one chip. Spread-style LEDs, on the other hand, provide a wider, more even distribution of light than center-point LEDs.

As a result of their high output, COB led grow lights can generate more heat than regular LEDs and so necessitate the installation of cooling fans. They use full-spectrum white LED diodes that penetrate deeper into the canopy than spread-style LEDs.


Compactness is an advantage of traditional LED grow lamps, thus they’re a suitable fit for confined locations. The LEDs they utilize have a medium power output and are usually multicolored, unlike white LEDs, which only cover a portion of the color spectrum. Indoor growers may or may not find this to be aesthetically pleasing.

How do LED Grow Lights Work?

How do LED Grow Lights Work

Different semiconductors (Electrons and Holes) are used to provide a unique light spectrum for LED grow lights, unlike other fluorescent bulbs or lights. In addition to natural light, this spectrum of light aids in the growth of plants, making them stronger and healthier.

LED grow lights employ semiconductor chips instead of filaments or mercury or lead to produce light, making them more energy-efficient, environmentally friendly, and long-lasting.

Why Choose Full Spectrum LED Grow Lights?

Depending on their spectrum pattern, LED Grow lights emit varying wavelengths of light. There are different light wavelengths that stimulate plants at different points in their development, and hence you must verify the spectrum of a grow light before purchasing one. For example, an LED that is great for plants may not be so great for flowering.

However, a Full Spectrum LED Grow Light can be used at any stage of the plant’s development, allowing you to employ it for any purpose. A full-spectrum LED light provides light in a range of wavelengths that mimics the Sun’s rays. As a result, Full Spectrum Light emits all wavelengths of light that are emitted from the sun.

When it comes to the correct growth of many plants, they need more than just red or blue light. It’s preferable to use Full-Spectrum light for these plants. For example, the Cannabis plant requires different wavelengths of light at various growth stages, and so full-spectrum light is recommended for its healthy growth.

What Are PAR Values?

What Are PAR Values

For photosynthesis, plants rely on a certain light spectrum known as PAR. In terms of plant growth, the PAR values are based on the wavelengths between 400 and 700 nanometers. LED grow lights emit an enormous amount of light with a wide range of wavelengths, yet plants do not absorb any of it. Plants only take in some wavelengths of light and reflect the rest. In a nutshell, PAR is the quantity of light that plants can use.

The PAR value determines how effective a Grow LED light is. Micromoles of light emitted per square meter of area per second is the unit of measurement. Effectiveness depends on the LED light’s PAR (power output per unit area). When selecting a grow light for your indoor garden, be sure to look at the PAR value of each option.

600–1000 µmol/m²/s: A powerful beam of light. Flowering and growth are best supported in this range.

400–600 µmol/m²/s: Light with a medium strength. Early veg and stretching can be done in this soil type.

200–400 µmol/m²/s: Low-intensity beam. Suitable for seedlings and clones.

What is PPFD Value and its significance?

The PPFD Value of a grow LED light is just as important as PAR in assessing the light’s efficiency. For “Photosynthetic Photon Flux Density,” PPFD is an acronym.

Light intensity (PPFD) is a measure of how many light photons that fall within the PAR range hit a square meter per second over the course of a day (in micromoles). There’s no guarantee that the PPFD measurement will accurately reflect the amount of light that’s really reflected off of plants, but it’s still critical to determining the grow lamp’s efficiency. In general, the longer your light cycle, the lower your PPFD number will be.

What are the Benefits of Using LED Grow Lights?

Compared to HPS grow lights, LED Grow Lights are far superior.

1) Economical: As a result of using less energy and heat to create more useable light, LED grow lights are a far more cost-effective and handy solution than traditional lights, which have long electricity bills.

2) Eco-Friendly: LED lights are environmentally safe and recyclable since they do not contain dangerous gases or compounds like mercury or lead.

3) Longer Lifespan: LED lights are more environmentally friendly since they consume less energy to create the same amount of heat. Designed to last up to 102,000 hours, they are built to last a long time. They are more long-lasting and durable than conventional lights because of their low operating temperature.

4) Efficiency: More than 40-60 % of the power generated by LED lights is used to provide useable light, compared to ordinary incandescent bulbs. Unlike traditional lights, LED grow lights emit extremely little heat and use 80% of their power to produce light instead of wasting 20%-40% of their energy.

5) Less Heat Production: Due to the lack of 730nm wavelengths in LED lights, the plants receive only a small amount of heat, and the rest comes from the panel itself. As a result, grow lights are ideal for the cultivation of plants, as they do not produce as much heat as other types of lighting.

6) Better Crop Production: By giving plants with appropriate lighting in the form of grow lights, they are able to grow at a faster rate and produce more crops.


Some of the most frequently asked questions about LED grow lights have been answered below.

Q. Which lights do professional growers use?

LEDs are becoming more popular in the lighting sector, however HIDs and fluorescents are still widely used by professionals. Homeowners should choose for LEDs over incandescent bulbs because of their lower energy use.

Q. How far should LED lights be from plants?

Generally speaking, LED lights should be at least 12 inches above your plants in order to avoid damaging their leaves.

Q. What advantages do LED grow lights have over HPS lights?

LED grow lights use less energy than high-pressure sodium (HPS) lights, making them more environmentally friendly. Because they don’t produce as much heat, you don’t have to worry about keeping the temperature at a comfortable level.

Q: Can plants get too much artificial light?

Plants in the wild come to mind. Not all of the time are they in the sun. Artificial lighting is the same. You can harm your plants by leaving the lights on for too long, as the light’s effect on metabolism can affect how they blossom. Lights, even LEDs, can dry out or even burn plants if they are not used properly.

Q: How much light do I need for a 10×10 grow room?

The basic rule of thumb is that you need 25-50 watts (equivalent) of light per square foot, depending on the type of lights you use and the type of plants you’re cultivating. As a starting point, you’ll need to do a lot more research into your plants if you’re planning on putting together a grow room that large.

Q: Which is better LED or HPS?

Many growers still use HPS lights, or high-pressure sodium, despite this article’s focus on LEDs. LED lights use less power and have better spectral coverage than incandescent bulbs. Although HPS is more expensive to begin with, the fixtures are simpler to repair and replace as necessary.
