The Photonican Aurora LED Grow Light (820W) is a high-performance lighting solution designed for serious indoor cultivators seeking maximum yield and efficiency. With its advanced features and robust build, it stands out in the competitive grow light market.

Grow light spectrum
The new Photonican 820W Pro introduces a new spectrum which offers increases in yields and harvest quality. This light has added 640nm red diodes alongside 660nm red diodes to widen the red peak. The latest research (link below) shows increases in dry yield, terpenes and cannabinoids mainly due to increases in photosynthetic efficiency.

The Photonican 820w pro also includes far red diodes adding 730nm far red to the spectrum output.

Coverage
This led bar grow light is suited for a 5ft x 5ft (1.5mx 1.5m) grow space. We tested it at a minimum hanging height of 12" which delivers the highest PAR intensity (photosynthetically active radiation) to the plant canopy.

However if you prefer to deliver the most uniform light spread over the plant canopy we recommend 18" hanging height. There is a 4% reduction in average PAR intensity but the light spread is more even.

The Photonican Aurora 820 watt system efficiency is excellent delivering 2.52 usable PPF per watt to the grow area. This is at the higher end of the market and excellent for a grow light at this price point.
Construction and build quality
It is a foldable LED bar grow light with 8 LED bars. There is no assembly require, simply unfold the light and hang it up. The LED driver is then mounted on the back.
The LED driver is dimmable with adjustment from 20% to 100% in 20% increments. You can also daisy chain multiple units for dimming or add the Photonican LED grow light controller.
Smart control
The light is compatible with external smart controllers (sold separately), offering functionalities like automated dimming in 1% increments, temperature safety control, and sunrise/sunset simulation modes. This level of control is beneficial for growers aiming to fine-tune their cultivation environment for optimal plant health and productivity
