Photontek SQ 300W PRO LED Grow Light

PhotonTek SQ300W PRO LED Grow Light

(816 µmol/s • 2.7 µmol/J)

Compact, high-intensity full-spectrum lighting for tight spaces up to 3.3’ x 3.3’.

The PhotonTek SQ300W PRO is a powerful square-footprint LED designed for smaller grow areas where uniform coverage and canopy penetration matter most. Built with latest-generation top-bin White, Red, and Far-Red diodes and a world-class P-Tek controllable driver, it delivers high PPFD with a smooth, even spread—without hotspots.

The LED bars are protected with PhotonTek’s Clear Glue coating for 99% light transmittance, added corrosion resistance, and long diode life, all in an IP65 rated design made for real grow environments.
