SP 3000R Red Spectrum 300W LED Grow Light

Mars Hydro SP 3000R is a 300 W red-spectrum bar light designed for greenhouse supplemental or top lighting and 2x4 ft grow spaces.

The fixture uses Bridgelux LEDs, passive cooling, and an IP65 rating. A slim 42.79 x 3.97 x 3.97 in form minimizes shading; daisy-chain control allows up to 50 lights with 0–100% dimming. Recommended coverage is 2x4 ft. Electrical specs are AC100–277 V, 300 W ±5%. Stated lifespan is 50,000 hours. Dimensions and specs align with Mars Hydro’s SP-series updates introduced in 2024.
