As succulent growers, we clearly understand the difficulties in finding the most suitable grow lights for our succulents. We have purchased and tested many types of grow lights such as LED lights and HPS grow lights from Amazon’s best-value category, Amazon’s editor’s choice, and Amazon’s popular picks, before finally discovering the best LED grow lights on Amazon for succulents and indoor plants. In addition, you can choose one from ECO Farm.
Specifications to look for in the best cheap LED grow lights:
1. Light Intensity
The best cheap LED grow lights will provide enough light intensity for your plants to grow from seedling to harvest. This means you need 20 to 40 moles of light per day.
To reach 40 moles for maximum yield, you need a grow light that delivers between 600 μmol (for an 18-hour vegetative phase) and 925 μmol (for a 12-hour flowering phase) of PPFD light.
As long as you have sufficient light intensity, you don’t need to worry about wattage, because wattage is not an accurate indicator of a grow light’s performance.
2. Good Spectrum
The best cheap LED grow lights will have a balanced spectrum. Some low-performing lights have too much blue or too much red, forcing you to wait longer during the Vegetative or Flowering stages.
Light spectrum has not been fully proven by science yet, so some grow lights will differ slightly. But overall, your LED grow light should use a white spectrum or a balanced mix of blue and red (similar to purple). You can determine this by looking at the spectral chart of each light.
3. Coverage Area
The best cheap LED grow lights will cover the area you need at a good price. Carefully evaluate the coverage area of inexpensive grow lights.
Most lights in the “best cheap” category will not effectively cover more than 2×2 feet. If you need to cover a larger space, consider using multiple lights at the same time, or refer to my article “Best LED Grow Lights for 4×4 Grow Tents” to find a light that can cover a wider area.

Things to consider before buying grow lights
LED lights are changing the way we grow plants, allowing both professionals and enthusiasts to achieve optimal environmental efficiency with minimal effort.
LED grow lights offer certain advantages, but choosing the right product is often quite complex. Grow lights make indoor gardening much easier, and fortunately, there are many grow light systems to choose from.
Choosing LED grow lights can be quite challenging because so many companies that manufacture LED lights claim to have the best products in the world. However, if you pay attention to a few factors, the decision will not be too difficult.
Budget:
Clearly, cost will influence your choice. If you’re just starting out, buy a cheaper option that still meets your needs. If you have more experience and have begun optimizing your setup, choose the highest-quality option you can afford.
Full Spectrum:
Spectrum refers to the wavelengths of light emitted by the grow light. Plants need not only visible light but also UV and infrared at specific stages of growth to ensure maximum yields. Ideally, you should choose a light that mimics the light spectrum emitted by the sun as closely as possible. Most LED lights emit a full spectrum, but lower-quality lights may not. Be sure that the light you buy emits not only visible light but also UV and IR, with a balanced blue/red light ratio. If you want healthy, fast-growing plants, you need full-spectrum lighting.
Coverage Distance:
Each light has a specific area it can cover, and it’s important to know what that range is because all your plants must be fully illuminated at all times. When calculating this distance, you need to consider your grow space size as well as the number of plants you can fit in that area.
Efficiency:
You should look for grow lights that consume as little electricity as possible while still allowing your plants to grow and the light to operate at full capacity. The lower the energy consumption, the longer the light will last, and the more electricity you will save. When estimating the lifespan of the best LED grow lights, remember that they will be running for long periods, especially during the growing cycle and early seed starting.
Light Control:
The amount of LED lighting your plants need varies depending on their stage of growth. For example, plants in the vegetative stage are typically exposed to LED lighting for 18 hours per day, while flowering plants require around 12 hours of LED lighting. Although you can manually switch the lights on and off, using a timer will make your life much easier.
Conclusion
It is clear that the importance of LED grow lights is extremely significant. They have contributed greatly to the high yields and quality of crops such as cannabis, flowers, and more. This also helps growers and gardeners successfully overcome the challenges of indoor cultivation.
Seasonal growers have used this technology to elevate gardening to a new level. However, several factors are very important when using full-spectrum LED grow lights, as there are many different types available on the market.
