Spider Farmer SE5000 (LED):
Each SE5000 provides a true power draw of about 480W, and covers roughly 4x4 ft effectively.
High efficiency LEDs (~2.7 µmol/J), full-spectrum, better canopy penetration due to bar-style design.
Potential yield: 1.5–2.0 grams per watt under optimal conditions.
Total potential yield for 2 units: ~1,400–1,900 grams (depending on strain, CO₂, and grow skill).
600W HPS (x2):
Each 600W HPS draws 600W, for a total of 1,200W.
Less efficient (~1.3–1.6 µmol/J), mostly red/yellow light spectrum.
Potential yield: 0.8–1.2 grams per watt under good conditions.
Total potential yield: ~1,000–1,400 grams.
Basically, two Spider Farmer SE5000s outperform two 600W HPS lights in nearly every way: higher efficiency, better yield per watt, lower power draw, and cooler operation.
