Sylvania SHP-TS GroLux 400W HPS Bulb

Enhanced Spectrum HPS Grow Light for Complete Plant Cycles

The Sylvania SHP-TS Grolux 400W represents a breakthrough in high-pressure sodium lighting technology, featuring an enhanced blue and red light spectrum that makes it suitable for both vegetative growth and flowering phases. Unlike traditional HPS bulbs that primarily emit yellow-orange light, this advanced grow light incorporates additional blue wavelengths crucial for healthy plant development during all growth stages.

Superior Performance and Extended Lifespan

This professional-grade grow light delivers exceptional photometric performance with industry-leading efficiency and reliability. The patented construction and unique design ensure consistent light output throughout its extended operational life, making it a cost-effective choice for serious indoor growers.

• High luminous output of 58,000 lumens for intense light coverage
• Excellent PAR value of 713 μmol/s for optimal photosynthetic activity
• Enhanced blue and red spectrum suitable for both vegetative and flowering phases
• Extended 26,000-hour lifespan reduces replacement frequency and costs
• Superior light stability - maintains efficiency longer than standard HPS bulbs
• Energy efficiency class A++ for reduced operating costs
• Compatible with both horizontal and vertical mounting orientations

Optimal Usage for Indoor Cultivation

The Sylvania SHP-TS Grolux excels in medium to large growing spaces where powerful, full-spectrum lighting is essential. Its 400W power output provides sufficient intensity for a 1.2m x 1.2m growing area during flowering or up to 1.5m x 1.5m during vegetative growth. The enhanced spectrum eliminates the need for separate metal halide bulbs during vegetative phases, simplifying your lighting setup while maintaining optimal plant health.

This grow light works best when paired with quality digital or magnetic ballasts rated for 400W HPS operation. Maintain proper distance from canopy - typically 40-60cm depending on growth stage and environmental conditions. For hydroponic systems, this consistent, powerful light source ensures uniform growth across your entire cultivation area.

Professional Growing Applications

Ideal for commercial growers, hydroponic enthusiasts, and serious hobbyists who demand reliable performance and consistent results. The broad spectrum output makes it particularly valuable for growers using hydroponic and indoor growing systems where light quality directly impacts yield and plant quality. Perfect for both beginners following our hydroponics for beginners guide and experienced cultivators seeking maximum efficiency.
