PhotonTek SQ200W Pro LED Grow Light 205W | 508 µmol/s, 2.5 µmol/J – 240v

PhotonTek SQ200W Pro LED for 2x2 Tents and Small Cabinets A 2x2 tent leaves no room for a fan-cooled fixture that hums all night beside the bed. The SQ200W Pro solves that with a square bar array and a passive heat sink, so nothing moves and nothing buzzes. It draws 205W and delivers 508 µmol/s PPF, a fixture efficacy of 2.5 µmol/J. The footprint is rated at up to 2.6 x 2.6 ft for both veg and flower. The frame measures 20.65 x 20.65 x 2.82 in and weighs 8.82 lbs, light enough for a standard tent crossbar. Heat output sits near 703 BTU/h, which one small inline fan clears without trouble. The driver accepts 120–277V, pulling 1.76A on a household outlet. The diode mix blends high-bin white with deep red and far red at a 120° beam angle. A clear-glue coat seals the bars to IP65 while passing about 99% of the light. The diodes carry a rated life of 60,000 hours. Running a 200W LED Grow Light in a Tight Space The square layout is the reason this light works close to the plants. A round or bar fixture of the same wattage throws hot spots when hung low, while this array keeps the center and corners closer together. Most growers start around 18 inches above the tops in early veg and work down during flower. Confirm with a PAR meter, because tent walls reflect more light than the chart assumes. The included dimmer clicks through off, a quarter, half, three-quarters and full, which covers seedlings through late bloom. For finer ramps and sunrise schedules, the P-Tek Digital Controller or any 0–10V room controller takes over. One honest limit is the footprint. It covers a full 2x2, but a 3x3 needs more photons than a single fixture of this size provides. Growers filling a 3x3 usually step up to the SQ300W instead of stretching this one. It also carries CSA, FCC and IC compliance rather than an ETL or DLC listing, so check before counting on a utility rebate. Key Features 508 µmol/s at 2.5 µmol/J: Solid flowering intensity over a small canopy without pulling more than 205W from the wall. Fanless Passive Cooling: No moving parts means silent operation in closets, cabinets and bedroom tents. Square Bar Array: Keeps PPFD even from center to corners when the fixture hangs close to the canopy. IP65 Clear-Glue Coating: Seals the diodes against humidity and foliar spray while passing about 99% of the light. Stepped 0-10V Dimmer Included: Off, 25, 50, 75 and 100% settings cover seedlings through late bloom out of the box. Controller Compatible: Works with the P-Tek Digital Controller or universal 0-10V room controllers for scheduled ramps.
