Description
Photontek SQ300W Pro Full Spectrum LED Grow Light Fixture
The Photontek SQ 300W is a full-spectrum LED grow light for those tight spaces.
Designed for low hangs, the SQ 300W gives you balanced PPFD intensities at a low wattage.
The SQ 300W features a high photon efficacy at 2.7 umol/J. You get a homogenous light spread at close distances, so your plants get sufficient lighting.
Behind the power of the SQ 300W are the Photontek drivers and premium white, red & far-red LEDs.
And with its square design, the SQ 300W delivers outstanding light distribution.
Unlock the potential of the SQ 300W with the Photontek Digital Lighting Controller, which lets you manage up to 100 grow lights.
But even if you have your controller system, the SQ 300W integrates easily with any control system that uses a 0-10V output signal or an RJ to 0-10V control adaptor.
Features

Full Spectrum and Efficient
The SQ 300W is a full spectrum LED fixture that covers the whole growth cycle of plants in smaller grow spaces.

Square design
The square formation of the SQ 300W provides better lighting quality, especially at lower hangs.

High-quality components
The SQ 300W uses only the best components, such as the Photontek Driver, and premium white, red & far-red LEDs.
