The PhotonTek® SQ 300W Pro LED Grow Light is a high-output, compact square board LED fixture designed for small grow tents, vertical racks, and targeted multi-fixture commercial setups. Consuming 300 watts of power, this fixture generates a photon flux output of 816 µmol/s at a high photon efficacy of 2.7 µmol/J. Engineered as an energy-efficient replacement for traditional 500W to 600W HPS/MH lighting systems, it significantly reduces electrical consumption and ambient thermal load while providing uniform light distribution across a 3.3' x 3.3' vegetative or 3' x 3' flowering footprint.

 

Key Features

• Compact Square Footprint: Tailored for small footprint grow spaces, providing uniform edge-to-edge canopy coverage over 3' × 3' flowering or 3.3' × 3.3' vegetative areas.

 

• 600W HPS Equivalent: Consumes only 300W while matching the photon output of legacy 500W–600W single-ended HID fixtures.

 

• 2.7 µmol/J Photon Efficacy: High efficiency rating lowers power draw and thermal emissions inside grow environments.

 

• Sunlike Full Spectrum: Blends premium Lumileds white and Osram deep red diodes for balanced vegetative growth and bloom response.

 

• Silent Passive Thermal Control: Heavy-duty aluminum heat sink dissipates heat efficiently without noisy mechanical fans (0 dB operation).

 

• IP65 Water & Dust Rating: Protective clear glue coating shields diodes against moisture and dust in humid indoor environments.

 

• Centralized Controller Dimming: Features an onboard 0–10V dimmer knob (25%, 50%, 75%, 100%) and supports daisy-chaining up to 100 fixtures.

 

Equipped with top-bin Lumileds white LEDs and Osram 660nm deep red diodes, the SQ 300W Pro emits a sunlike, full-phase spectrum optimized for all plant growth stages from seedling through harvest. The fixture features a solid square aluminum frame for passive fanless heat dissipation, IP65 water and dust resistance with clear glue diode protection, manual step-dimming (0%–100%), and 0–10V digital controller port compatibility for seamless multi-fixture commercial integration.
