It’s ideal for a 4x4 grow space for flowering and can extend up to 5x5 feet for vegetative growth​. 

However, in warmer environments, the light may require additional cooling measures due to its heat output. Although it uses heat sinks for cooling, it lacks fans, which can lead to higher temperatures in enclosed spaces​

How Many Lumens Do I Need to Grow Vegetables Indoors

Lumens measure the total quantity of visible light emitted by a light source. The more lumens the light emits, the brighter the light your vegetables bear. For indoor vegetables, we normally estimate the required lumens by the plant growth stage and the space you're covering. In general, vegetable seedlings aim for 2,000 to 3,000 lumens per square foot. 

For the vegetative stage, target between 5,000 to 10,000 lumens per square foot. Flowering stage even more. That’s to say, the indoor grow light you choose should at least be powerful enough to emit 2000 lumens.  

What Level of Light Is Ideal for Growing Vegetables

For healthy growth, vegetables generally need about 14 to 18 hours of light per day. This extended lighting period should be followed by 6 to 10 hours of darkness, which is vital for their development and productivity. Fortunately, LED grow lights are energy-efficient, making them a cost-effective option even when used for the full 18 hours a day. This efficiency ensures that your electricity bills remain low without sacrificing the growth quality of your plants.

LED grow lights stand out due to their energy-saving capabilities. They are designed to not only consume less energy but also to use it more effectively. These lights operate at cooler temperatures, emit a focused beam of light, offer a beneficial light spectrum for plant growth, and do not require additional ballasts. These factors contribute to their enhanced energy efficiency and effectiveness.

When setting up LED grow lights in your indoor vegetable growing space, it’s important to maintain the right distance between the lights and the plant canopy. A distance of about 10 to 12 inches (approximately 25 to 30 cm) is recommended. This spacing helps to prevent potential plant damage from the intense light. To ensure the distance is adequate, you can perform a simple test by placing your hand above the plants – if you don't feel excessive heat, the distance is likely appropriate.
