PhotonTek SQ300W Pro LED
The PhotonTek SQ300W Pro LED is a compact, powerful full-spectrum horticultural grow light for growers who want professional lighting performance in smaller indoor cultivation spaces. Ideal for grow tents, grow rooms, home cultivation, and compact indoor gardens, this efficient LED fixture delivers strong, uniform light for propagation, vegetative growth, and flowering.
Producing an impressive PPF output of 816 µmol/s with a high fixture efficacy of 2.7 µmol/J, the PhotonTek SQ300W Pro LED delivers excellent light intensity while using only 310W of input power. Its compact square design provides even illumination across a grow area of up to 3.3' × 3.3', making it an excellent solution for growers who want powerful output without installing a larger multi-bar fixture.
The SQ300W Pro uses a carefully balanced combination of high-spec white, red and far-red diodes to create a complete horticultural spectrum suitable for the entire plant growth cycle. This balanced full-spectrum output provides consistent lighting from early plant development through vegetative growth and flowering.
PhotonTek's innovative square LED-bar layout creates a uniform light spread with minimal hotspots. Its broad 120° light distribution helps spread photons evenly across the canopy, providing excellent light penetration while allowing the fixture to operate effectively at relatively close mounting distances.
The LED bars feature PhotonTek's Clear Glue protection technology, which provides up to 99% light transmittance while helping protect the diodes against moisture and corrosion. Combined with its durable IP65 water- and dust-resistant rating, the SQ300W Pro is designed for dependable use in demanding indoor horticultural environments.
The fixture also uses passive thermal management to dissipate heat efficiently without fans or moving components. This fanless design reduces noise and maintenance while supporting reliable long-term operation.
For precise control throughout the growing cycle, the PhotonTek SQ300W Pro LED is fully dimmable. The included 0–10V light dimmer provides settings of OFF, 25%, 50%, 75% and 100%, allowing growers to easily adjust PPFD levels according to plant size, growth stage and environmental conditions.
For more advanced lighting automation, the SQ300W Pro can connect to the PhotonTek Digital Lighting Controller, providing programmable lighting schedules, automated dimming, temperature safety controls, and sunrise and sunset simulation.
With a rated lifetime of approximately 60,000 hours, quiet fanless operation and a 3-year manufacturer's warranty, the PhotonTek SQ300W Pro LED combines powerful full-spectrum performance, compact dimensions and professional-grade construction in an easy-to-use grow light.
