Efficient, durable HPS lamp for faster, healthier year-round plant growth
PLANTASTAR lamps are designed to match the absorption spectrum of plants. were developed specifically for applications in commercial horticulture. They enable plants to be intensively cultivated throughout the year.
These lamps ensure optimum production processes thanks to their long life, long relamping intervals and low maintenance costs.
Extremely constant luminous flux during the first 10,000 hours of operation. It is advisable to replace the lamps after this time or every two years.
PLANTASTAR 250 are especially suitable for the exposition of tall vegetables.
Your benefits:
• Specially matched to the absorption spectrum for photosynthesis
• For faster, healthier plant growth
• Extremely constant photon flux
• Very high luminous efficacy of up to 145 lm/W
• Robust shockproof lamp design with elastic support for the burner
• High-quality corrosion-resistant base, ideal for use in moist surroundings
