The Best LED Grow Lights Option


When attempting to grow vegetables indoors or to start plants from seed, natural light isn’t always enough, especially in colder climates or seasons. Though some houseplants can survive in low lighting conditions, others need added light from grow lights.

Light-emitting diode (LED) grow lights are the go-to pick for many home gardeners, because they’re energy-efficient and eco-friendly options, and they can produce full-spectrum light. LED grow lights are different from the standard LED bulbs such as those used in home light fixtures. Read on to learn more about how to choose the best LED grow lights for your home.

The Best LED Grow Lights Option


Types of LED Grow Lights

LED grow lights come in a variety of forms. Learning about the most popular ones can help you choose a suitable type for your indoor garden.


Spread-style LED lights have many small individual lights spread out over their entire surface area, which makes them effective in providing light to a large number of plants. The two main subcategories of spread lights are spider-style and quantum board.

  • Quantum board lights use a large number of small LED grow lights spread out over a relatively large, flat surface area. They use full-spectrum white LED diodes and typically feature passive cooling, allowing the plants to be placed immediately under them without the danger of too much heat emission.
  • Spider-style lights feature multiple LEDs on narrow “arms” in an open bar design rather than on a solid board. These tend to be more expensive than quantum board lights.

Chip on Board (COB)

Chip on board (COB) lights feature a number of tiny LEDs placed close together on a single chip, resulting in a single powerful point of light. While the center point of the area they cover receives optimal lighting, they don’t offer the same level of widespread, equal coverage as spread-style LEDs.

Since they’re so powerful, COB lights often emit more heat than other types of LEDs and may require the use of fans to cool down the area. They use full-spectrum white LED diodes and provide deeper canopy penetration than spread-style LEDs.


Traditional LED grow lamps are usually compact, making them a good choice for small spaces. They use LEDs that provide medium power and typically feature multicolored LEDs that cover the full spectrum of color frequencies, unlike white LEDs. This gives their light a colorful appearance that indoor growers might or might not like.

What to Consider When Choosing the Best LED Grow Lights

The following sections detail some of the most important qualities to keep in mind when shopping for the best LED grow lights for your needs.

Light Spectrum 

Natural sunlight features all the colors on the electromagnetic spectrum. Some LED lights can reproduce only certain color frequencies, while full-spectrum white LED lights produce all the hues necessary for every stage of the growing process.

  • Blue light helps plants grow in the earliest stages of their lives. It’s the first color plants can absorb in their vegetative state.
  • Purple light is also used in the vegetative state; however, it’s not as effective for photosynthesis as blue light.
  • Red light helps in the latter stages of growing and is essential for buds to flower.
  • White light encompasses all the colors of the spectrum. Used alone, it can be effective for every developmental stage.


It’s a bit difficult to compare LED grow lights because manufacturers use a variety of metrics to measure the power of their lights and the amount of light they emit. The brightness of LED lights is measured in lumens. Seedlings require approximately 2,000 lumens per square foot to thrive, while flowering plants may need as much as 10,000 lumens.

While lumens measure visible light, biologists often use photosynthetic photon flux (PPF) or photosynthetic photon flux density (PPFD) to measure light intensity in terms of the light that indoor plants will actually absorb. PPF is measured in μmol/second (or micromoles per second), which is the number of photons of light emitted every second. PPFD is also measured in micromole/m2/s and measures the density of light distributed per square meter per second. The higher the PPF and PPFD, the more effective the light should be.

Heat Output

One of the risks when using a grow light is that the heat emitted by the bulbs can damage your plants. However, LED lights give off very little heat relative to the amount of light they produce. But they do produce some heat, so many models are equipped with built-in cooling systems to ensure proper temperature regulation.

Some LED lights have aluminum heat sinks, and others come equipped with fans. A unit with a fan might be loud, so factor noise level into your choice when selecting a grow light.

Coverage and Wattage

To choose the right plant grow light, you’ll first need to establish how much coverage you need. To do this, group the plants together and measure the square footage they take up. Most grow lights will clearly list the coverage they provide.

To establish how much electricity a light uses, look for its “actual power draw” or “actual power consumption.” This is measured in watts and gives a good indication of the light’s power. Bulb wattage is not a good indicator because LEDs are designed to be energy efficient.


Many LED grow lights are designed to link to other units to cover larger areas, which is typically referred to as “daisy-chain connectivity.” Products with this capability simply plug into each other and then plug into one outlet, which minimizes the number of cords required for setup.

Our Top Picks

The following picks consider the features described, including light spectrum, power, and heat output. This list offers choices for a top-notch LED grow light in various categories, available in a range of price points.

Our Verdict

After reviewing this guide, you should now know more about shopping for plant grow lights for your indoor plants. We recommend the MARS HYDRO grow light for its low power consumption, full-spectrum LEDs, and relatively affordable price. Those on a budget may appreciate the Juhefa full-spectrum grow lamp, which offers great performance at a lower price point.

How We Chose the Best LED Grow Lights

Years of experience covering home and garden products as well as extensive product research went into creating this guide. We explored more than 25 options for LED growing lights and weighed a number of practical considerations before making our recommendations.

Since different types of plants require different color frequencies of light in order to thrive, we chose grow lights with full-spectrum white LEDs as well as options that featured specific colors for particular plant needs. To provide variety for shoppers, we opted to feature options for traditional, spread-style, and chip on board (COB) lights. We aimed to primarily include LED grow lighting that features a low actual power draw to ensure low energy costs and prevent excess power consumption.


For readers who still have questions about LED plant lights, here are some answers to some commonly asked questions.

Q: Which lights do professional growers use? 

Cheap LED grow lights for vegetables won’t perform at the same level as those used by professional growers. Professionals generally use high-intensity discharge lamps (HID) or fluorescents, though the industry is shifting to favor LEDs. Because of their energy efficiency, LEDs are a better choice for home use.

Q: How many watts per plant do I need?

When comparing the power of various grow lights, look at the “actual power draw” or “actual power consumption” in watts. Generally speaking, grow lights should use 32 watts per square foot of grow space at the absolute minimum, though 50 to 80 watts per square foot is ideal.

The actual brightness of LED lights is measured in lumens rather than watts, which is another way of measuring light intensity. Vegetables typically require 2,200 lumens per square foot, while other plants generally need approximately 1,375 lumens per square foot.

Q: How far should LED lights be from plants?

LED lights should generally be at least 12 inches above your plants to prevent leaf burn.

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

LED grow lights are more energy efficient than high-pressure sodium (or HPS) lights. They also emit less heat, which means you don’t have to worry as much about temperature regulation.
