Lighting is a crucial factor when it comes to growing plants. Keeping your plants alive can be a challenging task, but growing them indoors is more challenging. Some houses aren't ideal for growing plants just because they are dark. This is where the LED grow lights come in.
There are a lot of benefits that come with these grow lights; energy-efficient, eco-friendly, and produce full-spectrum light. They are considered to be one of the best indoor lights on the market, especially if you find the right one for your plants.
LED grow lights are quite different from the standard LED bulbs, for example, the home light fixtures. They are very effective in mimicking the light from the sun to give your plants the light that they need to grow.
Once you make a decision to invest in an indoor grow light, you should buy one that perfectly matches your needs. Although, this is easier said than done. To help you find the right one for you, we have a list of the best LED lights and a list of things you need to keep in mind while buying indoor lights.

What To Consider Before Buying an LED Grow Light
1. Light Spectrum
Some LED lights produce only some color frequencies. However, because we're trying to replicate the natural sunlight, which features all the colors, we need a full spectrum LED. A full-spectrum LED lights produce all the colors necessary for every stage of the growing process.
Some of the light spectrum colors include;
- Red Light- It is essential for the latter stages and for the buds to flower.
- Blue light- Helps in the earliest stages and is the first color that plants can absorb.
- Purple light- Used the same as the blue light; however, it’s not as effective as the blue light.
- White light- This can be used alone and is effective for every growing stage. They have all colors and are therefore considered as full spectrum.
The best LED grow lights should also have a uniform spectrum, such that if you have five plants under one light, they all get the same spectrum.
2. Size/Coverage Area
When it comes to the size of the grow light, you need to think about the number of plants you're planning to grow and also if you want something portable. You also need to consider the amount of space you have for placing it.
The coverage area of LED lights is the area that the light can illuminate at once. For optimum results, the surface area of the plantation unit must be smaller than or equal to the coverage area of the LED grow light.
If some parts of the plants are outside the illuminated area, it might cause non-uniform growth. You can also install lenses to either decrease or increase the coverage area of your LED grow light.
With these things in mind, you will be able to find the size of a grow light that perfectly matches your needs.
Manufacturers use different metrics to measure the power of lights, so it can be a little bit difficult to compare the LED grow lights. Most of the time, the brightness of LED lights is measured in lumens.
However, to measure the light intensity in terms of light that can actually be absorbed, scientists use photosynthetic photon flux (PPF), measured in μmol/second or photosynthetic photon flux density (PPFD) measured in μmol/m2/s.
PPF indicates the number of photons emitted per second, while the PPFD indicates the density of light distributed per square meter per second. The higher the PPF and PPFD, the more effective the light should be.
It is important to note that the bulb wattage is not a good indicator of a powerful LED. To know how powerful light is, look for its actual power draw or actual power consumption, commonly measured in watts.
There are different types of grow lights to consider, depending on the plants you have, the amount of natural light, and the location of the plants. These types include;
- Light Bulbs-It consists of a single light bulb and is excellent for growing small leafy greens with a full spectrum
- Light Bars- These are a single row of LED diodes that come in different spectrums, and they act as a supplement light to a main source of light.
- Light Panels- These are the most common and suitable for a full state of growth.
5. Heat Output
Using a grow light that emits a lot of heat can damage your plants. Most LED lights give off very little heat relative, but some may produce a lot of heat. It is quite important to find one that has a built-in cooling system to ensure the temperature is regulated. Some have aluminum heat sinks, while others have fans.
With the price of some of these LED grow lights, they are a significant investment, so you need to ensure that they last you for a long time. To find out the reliability of a grow light, you need to check the warranty as well as the reviews from buyers.
Furthermore, when it comes to installation, some grow lights types may require more effort than others. Also, some, especially the ones with fans, make some noise, and this should also be considered before making any purchase.
Frequently Asked Questions(FAQs) on LED Grow Lights
1. What is the best LED grow light?
The best LED grow light is EZORKAS 9 Dimmable Levels. It is not only a reputable model, but it also has great features such as an automatic timer function, 48 LED chips, and different intensities for different plants and different stages.
2. What type of LED is best for growing plants?
The best LED type for growing plants varies from one person to another because the grower needs are different. However, if you have a large plantation unit or plants that require more light, it is best to consider the LED panels since they can illuminate a wide area. If you have a smaller plantation unit, then you can consider the light bulbs since they are more affordable.
3. What lights do professional growers use?
The most widely used lights for growing vegetables and flowers are the Metal Halide HIDs and High-Pressure Sodium (HPS). However, the fluorescents and LEDs are now replacing these two lights because they are efficient and economical.
Any full-spectrum light should be a good choice for growing plants. This is because they provide all the rays of light required for plants to thrive fully.
4. What is the best wattage for LED grow lights?
The wattage required to grow plants differs from one plant to another. For example, plants that require high amounts of light, like tomatoes, need to have around 40 watts per square foot for them to flourish.
For plants that require low light and small leafy plants, like lettuce, you might only need about 20-30 watts per square foot.
Also, the wattage of different LED grow lights will determine how many plants can be used under them. For example, for a 450 watts LED light, the maximum number of plants that can be grown is nine.
