Spectrum LED Grow Lights Buyer’s Guide

Full Spectrum Led Grow Lights

When growing indoor plants, making artificial sunlight is oftentimes the most difficult hurdle and issue to face. Conventional grow lights emit very intense light, and they’re also power-hungry, which means that they consume a lot of electricity. This buying guide and the review list in the next chapter can help you learn how an inexpensive, but top-of-the-line LED grow light can significantly improve the health and yield of your indoor plants.

Questions to Consider Before Choosing a LED Grow Light

You have to ask yourself three questions before buying any LED system for your garden.

What are you growing?

Depending on the variety and species, plants have varied light requirements. In general, full-spectrum light is integral for photosynthesis. Red and blue lights are the most important.

For example, plants that originated from areas/nations near the equator need stronger light than those that originated from temperate or subtropical regions.

Plants that can thrive even in low-lighted areas such as herbs and lettuces will need at least 25 watts of lighting per square feet, while phototrophs, like tomatoes and angiosperms, need at least 55 watts.

How large is your indoor garden?

This is actually self-explanatory, but it’s worth mentioning here in case beginner gardeners forget. The larger your garden is, the more LED panels or bulbs you will need.

You have a lot of options to choose from, but remember that before buying a LED light, the type required depends on the size and shape of your grow area. 

How to choose the right type?

You have two options: blooming lights and full-spectrum lights. The latter can provide sufficient lighting throughout your plant’s life cycles.

If you opt for a more focused approach, blooming lights will suit you. For instance, you have separate growing areas for the life cycle of different flowering plants. In this scenario, a blooming light will be more suitable than a full-spectrum fixture.

Nevertheless, most modern LED grow lights have a blooming feature. And, you can turn the option ON or OFF at will.

A vegging LED light is used for the germination stage and a blooming light is for the flowering stage.

These days, many high-quality full-spectrum lights are incorporated with programmable options. With such features, you can turn a blooming light into a vegging light. When shopping for LED growing lights, you should keep that in mind and choose the product that offers the said option. 

What are the Features to Consider?

  • Choose a product with adjustable output light spectrum settings.
  • If you want high-powered LEDs, make sure that an adequate cooling system is included in the package.
  • Again, for high-powered systems, ensure that the printed circuit is a metal core printed circuit board or MCPB.
  • Consider LED fixtures that have a current driver circuit to ensure that there is a proper supply of direct current (DC).

What is a Full-Spectrum LED Light?

Why is this important? To answer this question, you must first understand what exactly is a light spectrum, or color wavelengths. A light spectrum is the various wavelengths of energy from a specific light source.

Light is measured in nanometers (nm). Each nanometer represents a band of light energy or a wavelength of light, and visible light is part of the spectrum from 380nm to 780nm.

In layman’s terms, your naked eyes can only see between 380 to 740 nanometers. Similarly, plant leaves absorb light included in the visible wavelength. Chlorophyll uses light from the visible range to manufacture food.

However, the green light is an exception since the pigments reflect the color green. They don’t actually absorb it.

In most cases, green plants only respond to red and blue colors. Those are the two most vital wavelengths for plant growth and reproduction. Fundamentally, blue light is required during the vegging phase and the red is for the blooming period.

Because of that, manufacturers produce focused grow lights. This feature is common in blooming lamps. Many modern LED lights for gardening have programmable settings. These include the option to change the color wavelength being emitted.

With those features, you can control the light type at the different wavelength essential for the different stages in a plant’s life cycle. LED lights that can emit the different color wavelengths in the visible spectrum are called full-spectrum LED lights.

Remember that the two most important factors in growing plants indoors are color wavelengths (light colors) and light output power (light intensity).

For power, go for a powerful light, like red and blue. For wavelength, choose a product that can emit many color wavelengths, or else, just buy a full-spectrum LED grow light!

That’s the reason why we have mostly featured full-spectrum grow lights in this article. In the testing phase, they are as effective as blooming lights, even in the germination phase. You can even use them to sprout seeds. 

Choosing the Best Grow Light for Your Plants

The most important factors to consider when shopping for grow lights are the ones listed below:

  • Coverage area
  • Wattage draw
  • Light intensity
  • Spectrum

In the previous section, we have talked about the light spectrum and the necessary colors for growing plants. In this part, we’re going to discuss the other three. So, don’t unfasten your seatbelts just yet because we still haven’t reached our destination.

Light intensity

This is the power of the product. Is its lighting enough to germinate the plant? If its light intensity isn’t enough, then it won’t be of any much help even though it can emit the right color.

For the plant’s growth stage or the germination phase, it must receive the right amount of light intensity. Power should also be uniform across the garden area especially if there are seedlings near the edges.

In terms of light intensity, it is not how it’s strong in the human eye, but it is the power of any given wavelength. It depends on the number of photons available for the flowering and growth of the plant.

So, how can you estimate the coverage of a particular fixture? How can you be sure that the intensity is uniform throughout the area? The answer to that is easy. You just have to consider the PFF reading.

What exactly is that? A PPF test measures the amount of PAR produced by a lighting system (per second. PAR stands for photosynthetic active radiation. PAR light drives photosynthesis. It’s mostly used in horticulture lighting.

When natural light is lacking and for increasing yields, gardeners and farmers use horticulture lighting to stimulate plant growth and flower production.

The PPF measurement is taken with the use of a specialized instrument—ab integrating sphere. This instrument measures and captures all photons emitted by a fixture or lighting system. So, how can you do this at home?

Wattage Draw

Growers use wattage draw to determine the potential of a fixture for growing. Generally, 400W HPS is enough for a 2x2 area, a 600W HPS is for a 3x3 area, and a 1000W HPS can flower plants in a 4x4 area.

Just remember that wattage doesn’t translate to light output. Efficacy, light output, and wattage draw are important for gardeners and farmers. Nevertheless, when energy consumption adds up, they would want the most amount of light for the least wattage. The higher the wattage of a fixture is, the more energy it consumes.

Coverage Area

The coverage area is your grow space size. Knowing the dimension of your grow area is very important when choosing a fixture. Large powerful lights can cover a 4x4 area. Some gardeners grow their cultivars in a 5x5 grow space. Commercial growers, on the one hand, need thousands of square feet.

Different manufacturers differ in opinions in terms of the proper way their lights should be utilized. Generally, lenses affect the range of lighting and its concentration. It’s recommended to follow the manufacturer’s PAR map when setting up light fixtures. That way, you can get the most of your LED spectrum lights.

A PAR map should include the following:

  • The intensity of emitted light at a given distance
  • Uniformity of the light across the compatible footprint
  • Intensities required for every phase of a plant’s life cycle
