18 Best Commercial LED Grow Lights for Grow Tents, Grow Rooms, Greenhouses, and Hydroponics

LED grow lights have become popular due to their energy efficiency, long lifespan, and ability to provide a full light spectrum. They’ve revolutionized the indoor growing industry by enabling year-round cultivation with low cost and convenience.

To choose LED grow lights, always consider factors such as efficiency, spectrum, PPF and PPFD values, and quality of the components. The best LED lights are energy efficient, saving money on electricity bills. They offer a full light spectrum mimicking natural light for optimal photosynthesis. They produce higher PPF and PPFD values for optimal growth and rich blooming. Their high-quality components are made of aluminum, steel, and similar durable materials to last longer and prevent damage. 

Some LED grow lights (AC Infinity, Vivosun) are more popular in the industry due to higher efficiency, better heat management, and higher quality components.

When choosing a full-spectrum LED grow light, consider the light’s spectrum coverage, energy efficiency, and heat management. For hydroponics, coverage area and waterproof rating are additional considerations. For greenhouses, consider the light’s ability to complement natural sunlight. For vertical farming, compact design and uniform light distribution are important. For commercial cannabis cultivation, look for lights with high PPFD values and a spectrum tailored for cannabis growth.

How Do You Choose the Best LED Grow Light?

To choose the best LED grow lights, consider factors such as LED grow light types, brands, spectrum/uniformity, coverage, wattage, PPF and PPFD, efficiency, adjustability, reliability and durability, footprint, certifications, ease of use, and installation.

Type of LED Grow Lights: There are three light types, including full-spectrum, high-intensity, and switchable LED lights. The full spectrum is suitable for all growth stages; high-intensity speeds up photosynthesis, while switchable allows you to switch between vegetative and blooming stages.

Brands of LED Grow Lights: Consider reputable brands known for quality and reliability, such as Mars Hydro, Spider Farmer, or AC Infinity.

Spectrum/Uniformity: Look for full-spectrum lights that cover all light ranges plants need, from UV to far-red. Uniformity ensures even light distribution across the plant canopy.

Grow Light Coverage: Make sure the light covers your entire growing area. The size of your garden will determine the number of lights required. For 2×2 tents, use 2 lights of 120 watts. For 4×4 tents, use 2 lights of 300 watts.   

Grow Light Wattage: Higher wattage means more light output, heat, and energy usage. For instance, a 2×2 tent requires 100-150 watts. 4×4 tents need 600 watts.

Grow Light Size: The size is again connected with wattage. For 3×3 tents, use 400 watts, while 10×10 tents use 1000 watts. 

PPF and PPFD: PPF measures the amount of light produced by the lamp per second. PPFD measures how much of that light reaches the plants. Higher values are better for optimal photosynthesis and healthy plant development. The best lights offer the right PPFD values, including 100-300µMol/m2/S for seedlings, 300-600µMol/m2/S for vegetative, and 600-750µMol/m2/S for flowers.

Efficiency: Look for lights with high luminous efficacy (more light for less electricity). Luminous efficacy measures the efficiency of a light source in converting power (usually electricity) into visible light, measured in lumens per watt. A higher value indicates a more efficient light source, as it produces more visible light with less power consumption source. For instance, LED lights can have a luminous efficacy as high as 300 lm/W.

Adjustability: Adjustable lights allow you to change the height and angle, ensuring optimal light exposure. The height of seedlings is 24-26 inches, while vegetative and flowering stages require 18-22 inches. 

Reliability/Durability: Opt for durable lights with strong build quality and good warranties. The best ones include sturdy frames (aluminum, steel) to ensure a longer lifespan and prevent frames from burning or other damage due to longer working hours. The good warranties include ones around 3-5 years, so opt for at least that period. 

Footprint: The footprint refers to the area that receives adequate light from the lamp. Bigger is usually better as they grow bigger and faster when they have more CO2 footprint inside the tent. 

Grow Light Certifications: Check for safety and performance certifications like UL, ETL, or ROHS. UL, ROHS, and ETL are certifications indicating compliance with safety and environmental standards for LED lights and other products.
