Description
Description
In a compact tent, a light that focuses on the center leaves the corners short. The PhotonTek SQ 300W Pro LED Grow Light uses an even square-bar arrangement designed for compact grow spaces. Because its PPFD stays high, you can hang it close to your plants and leave the same fixture in place from vegetative growth through flowering.
The bars combine higher-spec white, red, and far-red diodes. Pairing them on every bar is designed to spread that spectrum evenly across the footprint, so plants near the perimeter get light much like those in the center.
Key Features and Benefits of the PhotonTek SQ 300W Pro LED Grow Light
- High PPF Output: A total output of 816 µmol/s gives your plants intense light across a canopy measuring 3 x 3 feet in both veg and flower.
- 2.7 µmol/J Efficacy: More of the power you pay for reaches your plants as usable light.
- Stepped 0-10V Dimming: The included dimmer steps through off, 25, 50, 75, and 100 percent, so you can start seedlings gently and ramp up for flowering.
- 120-Degree Distribution: Each bar spreads light across a wide arc, helping it reach the corners of your grow area.
- IP65 Rating: An IP65 waterproof rating protects the fixture from dust and water spray in humid grow spaces.
- 60,000-Hour Lifespan: The LEDs are rated for 60,000 hours, giving you many grow cycles before you need to think about replacing the light.
- 310-Watt Draw: The fixture draws 310 watts and a maximum of 2.64 amps, so you can plan circuit loads before you hang it.
- Dual Voltage Support: It runs on 110-120-volt or 277-volt power, and the 5-15P plug fits standard household outlets.
- UL and CSA: UL and CSA certifications confirm that the light meets North American electrical safety standards for your grow space.
Planning Your 3 x 3 Tent Layout
At 22.08 x 22.08 x 2.82-Inches (L x W x H), the fixture sits centered over a 36-inch-wide tent with roughly 7 inches of open space on each side. A 120-degree spread helps light reach those edges once the fixture is raised above the canopy. A profile under 3 inches thick takes up very little headroom, which matters in shorter tents where you need every inch for plant height as the plants stretch in flower. At 11.46 pounds, the light hangs on the included hangers, with its cables and drivers ready for setup.
Sylvane's Expert Take
If you're growing in a 3 x 3 tent and want a single light from seedling to harvest, this one fits that space exactly. It works best hung low over an even, dense canopy, where the square-bar layout spreads light toward the perimeter plants.
Start young plants on the lower dimmer settings and raise intensity as the canopy fills in. The 2.7 µmol/J efficacy and the even edge-to-edge coverage are the 2 features that matter most for this footprint.
