Vivosun 4 pack Aerolight 400W LED grow light review

The Vivosun pack Aerolight 400W grow light package is designed for a 4ft x 4ft or 1.2m x 1.2m grow space. This is a package of 4 x 100W Aerolight led grow lights and the GrowHub controller.

The Aerolight 100W fixtures join together with 'H' shaped connector brackets that are fixed into position with grub screws. The lights are each powered separately with 4 x plugs and are connected together and to the Growhub controller by RJ11 network cables. The 4 lights then operate as one using the controller to adjust the brightness and light timing.

Each of the Aerolight 100W fixtures have an integrated circulatory fan which will push air down onto the canopy to improve CO2 exchange and general air circulation in the plant canopy. Again the fan speed and timing can be adjusted using the Growhub controller.

There is also the option to integrate the Vivosun AeroZesh extract fans. The Growhub controller has a temperature and humidity sensor with an app to monitor and control the grow room remotely. The controller can also be setup to active devices based on the grow room temperature and humidity. 

The white LEDs are Samsung 3000K warm white and 5000K cool white LM301Bs with added 390nm UVA, deep blue, dep red and 730nm Far red LEDs. The overall spectrum is about 4200K CT which is perfect for full cycle growing from seed to harvest.

 

I tested the fixture in its specified 4 x 4 grow area at 12" hanging height. The power consumed was 420.4 watts and the average PAR over the test area was 583 µmols resulting in a system efficiency of 2.0 µmols per watt or usable PPF per watt.

Overall a very innovative modular LED grow light system
