Who This Is For
- You are moving to a square fixture because your circular or bar lights leave the corners of your 3x3 tent under-lit.
- You are adding far-red spectrum coverage because your current white LEDs aren't pushing enough flower development.
- You are switching to external controllers because manually adjusting individual dimmers in a multi-rack setup is tedious.
What We Found
- The square frame shape is far better for 3x3 tents than long bars that waste light on the side walls.
- Photontek drivers run cooler than most generic brands, which helps keep your grow room temperature stable.
What Users Say
- Users who swapped out round LEDs say their corner plants finally match the height of those in the centre.
- Growers running multi-layer racks report the low profile design allowed them to add a whole extra shelf.

Spectrum
The Photontek SQ300W Pro uses a precisely engineered full spectrum built around higher-spec white, red, and far-red diodes. The broad white base supports vigorous growth across all lifecycle stages, dedicated red diodes maximize flowering response and photosynthetic efficiency, and far-red wavelengths trigger the Emerson Effect for deeper canopy penetration — all distributed through a 120° beam angle across the uniform 3.3'x3.3' square footprint.

FAQs
What is the ideal coverage area for the SQ300W Pro?
The SQ300W Pro is designed to perfectly cover a footprint of up to 3.3' x 3.3' (or 1m x 1m). Its square design ensures even light distribution across the entire area, eliminating hotspots and dark corners common with other LED grow lights.
Is this light suitable for all stages of plant growth?
Absolutely. The SQ300W Pro features a precisely engineered full spectrum that provides ideal light for all growth stages, from propagation and vegetative growth right through to the flowering phase. The included dimmer allows you to adjust intensity to suit your plants' specific needs at each stage.
Can I control this light with an external controller?
Yes, the SQ300W Pro is fully compatible with external grow light controllers. For the best experience and to daisy-chain multiple lights, we recommend the Photontek Digital Lighting Controller. It can also be used with any universal controller that utilizes a 0-10V signal.
How does the SQ300W Pro differ from the SQ200W Pro model?
The main difference is power and coverage. The SQ300W Pro operates at 310W and is ideal for a 3.3' x 3.3' area, while the smaller Photontek SQ200W Pro operates at 200W and is designed for a 2.7' x 2.7' space. Both share the same high-quality components and full-spectrum output, so you should choose based on the size of your grow area.
Can I add supplemental lighting like UV?
Yes, you can enhance your setup by adding supplemental lighting. For boosting resin production and potency during the flowering stage, the Photontek 30W UV LED Light Bar is an excellent addition that integrates seamlessly with your Photontek fixture.
