Series 3+ SQ² Red Spec 250 Watt is Budget LED’s square-layout variant aimed at even 3×3 ft flowering coverage. It uses two custom full‑spectrum boards built around Samsung LM301H white diodes with supplemental Samsung LH351H deep‑red at 660 nm and far‑red at 730 nm, plus a switchable 385 nm UVA channel. The passively cooled kit includes driver, dimmer, wiring, and hanging hardware. Actual draw is dimmable from roughly 30 W up to about 255 W, positioned to replace a single‑ended 500 W HID in compact tents. Typical footprints are 3×3 ft for flower and up to 4×4 ft for veg, with a recommended 18–24 in mounting height above the canopy.
