PhotonTek SQ300W Pro LED Grow Light

PhotonTek’s SQ300W Pro LED Full Spectrum Grow Light is designed and engineered for smaller, more compact grow spaces with an effective coverage area up to 3’ x 3’. This efficient, low power draw fixture combines the best light spectra available today with very-high PPFD levels for a healthy, potent plants.

PhotonTek LED Grow Lights are manufactured using only the highest-grade materials and components to ensure safe, dependable indoor garden lighting with industry leading performance. The SQ300W balances high quality, full spectrum light with high intensity PPFD delivered through a square design. These extraordinary grow lights produce intense, high-quality light suitable for your plant’s entire growth cycle, making these LEDs the smartest option for a higher and faster return on investment.

SQ Pro Line

The SQ Pro line boasts superior performance thanks to its square shape LED bar design built with the latest generation top bin White, Red and Far Red diodes and world class PhotonTek controllable drivers. The light’s LED bars are covered with a thin layer of Clear Glue, resulting in higher light transmittance of 99% without light loss, IP65 rating, extended lifetime of diodes and extra corrosion resistance.

The SQ300W Pro delivers a stunningly even spread of light at short distance from your plants so you get excellent penetration into the canopy without worrying about hotspots or excessive heat. Its innovative heat sink and use of passive natural convection mean this fanless unit is quiet and this design significantly improves the life span of the fixture thanks to no moving parts.


The PhotonTek SQ300W Pro LED Grow Light uses a blend of white, deep red & far red LEDs to deliver highly efficient light calibrated to provide high intensity, stable, and uniform light for optimal absorption by your plants

More Control

The SQ300W Pro LED fixture can be controlled externally with PhotonTek’s Digital Lighting Controller that features light timing, automated dimming (1% increments), temperature safety control, Sunrise & Sunset Mode for up to 100 fixtures per controller.

Universal Compatibility

PhotonTek Pro LED fixtures can be fully controlled with either the PhotonTek Digital Controller or with any other Control System that utilizes a 0-10V output signal. Even if your Universal Controller has an RJ port interface, you can still control the SQ300W by using a signal converter RJ to 0-10V control adaptor.

SQ300W Pro LED Stunning features with high quality components

The SQ300W Pro LED Grow Light produces very high levels of PPF output at 816 µmol/s and a Photon Efficacy (fixture efficiency) of 2.7 µmol/J. This helps create a consistent spread of light at close distances from the canopy for outstanding results when used in a 3.3’ x 3.3’ indoor grow area.
