              • Reliable - backed by a 90-day full-refund guarantee and a three-year limited warranty
              • High-quality and durable - protected by glue coating & lifespan of 100,000 hours
              • Heat-resistant, run quietly, and low energy consumption - a 5mm aluminum heat sink, no fans, 400W of power output
              Cons
              • It has some contact issues, resulting in uneven heat distribution

              This option is one of the best commercial-grade full-cycle horticulture lighting solutions you can count on. It is backed by a 90-day full-refund guarantee and a three-year limited warranty while the construction is durable, protected by glue coating (waterproof IP67 rated).

              It is heat-resistant efficiently by utilizing a 5mm aluminum heat sink (not fans, so it’s a lot quieter, too).

              What we appreciate the most is its low energy consumption, which offers comparable or better results than those 800W HID lights (this option is 400W – equivalent to 50% less heat consumption). In fact, the rating of PPF/Joule of MAXSISUN is 2.7 μmol/J @ 110V AC – very efficient.

              • Optimize leafy greens’ growth - 9 different bands of LEDs
              • Brighter and more efficient than the traditional 3W or 5W lights – the newest dual-chip technology
              • Low power consumption but same or better performance than the 1400W HPS lights – 390W of energy consumption
              Cons
              • Not as cool as the higher-end LED lights while operating
              • The glasses aren’t LED specific

              BESTVA DC Series 2000W is protected with the same warranty policies as the MAXSISUN (a 90-day money-back guarantee and a 3-year limited warranty). But because of offering 9 different bands of LEDs, it can be tailored to optimize leafy green growth, from seeds to harvest, just like in natural sunshine.

              Featuring 1200 pieces of SMD LEDs built with the newest dual-chip technology, which is a lot brighter and more efficient than the traditional 5W or 3W lights, it can maximize your crop yields.

              The most notable thing its coverage area is similar to most 1400W HPS lights – which is around 7.8' x 7.5' area at 24" height, while the energy consumption is just 3.5x lower, equivalent to 390W.

              Besides, it operates at around 50 or 60 degrees F lower than most other LEDs, meaning that it’ll last longer.

              How To Choose The Best Grow Light For 4x4 Tent?

              Plant Growth Stage & Light Wattage

              These two elements have a close connection with each other.

              While there’s a common rule of thumb – 1-square-foot grow space needs ~32W of power, this number might slightly change due to your plant growth stage. In detail, the vegetation stage needs 390-450 watts while the flowering stage is 512-650 watts.

              Light Intensity

              Again, this feature is decided by your plant growth stage and growing space. The most ideal light intensity range might be from 300 to 800 lumens for each square foot.

              Light Spectrum

              While a full spectrum includes blue, white, and red lights along with UV and infrared lights, research reveals that plants benefit from the exploit of blue, green, and red parts.

              Not to say that plants from stage to stage needs a specific light spectrum range to ensure maximum growth. There are 14 wavelengths, and specific ones needed for photosynthesis are employed in the engineering of grow lights for both the 1st and 2nd growing stage of a plant.

              When considering this feature, consider two solid things: full light spectrum and VEG/BLOOM settings.

              Which Brands Make The Best Grow Light For 4x4 Tent?

              Bestva LED

              Bestva LED is one of the best grow light manufacturers at the current because it’s based in California, USA where all the output values are rigorously controlled for the highest quality products. But what we appreciate the most is the price range is still very affordable.

              King LED Lights

              This is a long-standing company with over 8 years’ expertise in researching, developing, and manufacturing LED Grow lights and LED aquarium lights.

              FAQs

              What size LED light do I need for a 4x4 grow tent? How many watts do I need for a 4x4 grow tent?

              390-650 watts

              How many plants can I grow in a 4x4 tent?

              4-6 plants

              What size inline fan do I need for a 4x4 grow tent?

              ~200cfm

              Is it better to grow with a grow tent or open space?

              An open space offers more area to work in with unlimited airflow, however, it will surely have some hidden issues.

              A grow tent, meanwhile, is more controllable. It’s simpler to control the amount of light as well as density, heat, and water. Besides, it’s easier to keep private.

              Conclusion

              It’s always our goal to help make your decision-making process simpler and easier by spending hundreds of hours testing the best grow light for 4x4 tents on the market side-by-side.
