Compact LED for Tight Spaces: SQ300W Pro for 3x3 Footprints
The fixture pulls 310 watts of full-spectrum white, deep red 660nm, and far-red 730nm diodes. They sit across a 22.08 by 22.08 inch square bar array. The PhotonTek SQ300W Pro LED produces 816 µmol/s PPF at 2.7 µmol/J fixture efficacy. Independent tests measured peak PPFD near 1000 µmol/m² at a 44 cm hang height. Mid-700 µmol/m² readings appeared along the edges of the rated 3.3 by 3.3 ft footprint. The IP65 dimmable LED grow light runs on 120-277V at 50/60 Hz. It draws 2.72A at 120V. A clear-glue diode coating lifts light transmittance to 99 percent over standard cover materials.
Full-Spectrum LED Grow Light for 3x3 Grow Tent Builds
Growers typically hang the fixture 16 to 24 inches above the canopy in a 3x3 grow tent or compact rack tier. Then ramp from 25 percent through veg up to 100 percent in peak flower using the included 0-10V dimmer. The high efficacy 2.7 µmol/J fixture pulls about 310W to deliver PPF 816 umol/s full-spectrum output. Sizing two units side by side on a 120V 15A circuit becomes simple math at this current draw. External control through a 0-10V universal controller covers Trolmaster, Growlink, and similar room-management gear via RJ-to-0-10V adapter. The fanless passive-cooled LED design drops noise and extends the 60,000 hour rated lifetime in tight tent footprints.
Key Features
