Buyer's Guide
Light Spectrum
Full-spectrum LEDs (5000-6500K) mimic natural sunlight and work for all growth stages, while targeted red/blue combos (450nm blue, 660nm red) maximize flowering. For versatility, choose 6000K+ full-spectrum with at least 80 CRI. Avoid single-color purple lights—they distort plant color assessment.
Wattage and Coverage
Actual power draw matters more than inflated "equivalent" claims. Budget 25-50W per square foot for leafy greens, 50-80W for fruiting plants. A 1000W "equivalent" light often draws only 100-150W actual. Verify true wattage and beam angle—120° spreads light better than narrow 90° in small spaces.
Heat Output and Lifespan
LEDs run cooler than HPS/MH but still generate heat. Look for aluminum heat sinks and fans in fixtures over 50W. Quality LEDs last 50,000+ hours (6+ years at 18hrs/day) versus 2-3 years for cheap chips. Samsung LM301B/H or Osram diodes indicate premium components.
Adjustability
Dimmable lights let you reduce intensity for seedlings (25-50%) and ramp up for mature plants. Clip-on and gooseneck designs offer positioning flexibility in tight spaces. Timer compatibility (manual or smart) prevents light stress from inconsistent schedules.
