A Dutch greenhouse cultivating tomatoes year-round faced challenges with supplemental lighting during winter. Traditional HPS lamps consumed 1,000W per fixture, generated excessive heat, and lacked spectral optimization.

Queendom Solution

Queendom deployed COB-660/450 horticulture LED grow lights delivering targeted 660nm deep red and 450nm blue peaks matching chlorophyll absorption. The system achieved 2.8 umol/J PPE, 60% energy reduction vs HPS.

Key Advantages:

  • COB-660/450: Dual-peak matching chlorophyll absorption
  • PPE: 2.8 umol/J (60% more efficient than HPS)
  • PPFD: 800-2,000 umol/m2/s at canopy
  • Spectral tuning for vegetative vs flowering stages
  • IP65 housing: Resistant to 90%+ humidity
