• Optimal 2000K color temperature ideal for bloom phase stimulation
• Extended lifespan up to 32,000 hours reduces maintenance and replacement costs
• Compatible with both electromagnetic and digital ballast systems
• Dimmable capability for flexible light management throughout growth cycles
• Energy efficiency class A++ for reduced operational expenses
• Versatile horizontal and vertical mounting options

Optimal Flowering Applications

This HPS grow light excels during the flowering and fruiting stages of plant development, where its red-heavy spectrum triggers natural blooming responses. The 400W power output provides sufficient intensity for a 1.0m x 1.0m flowering area or up to 1.2m x 1.2m for less light-demanding crops. Position 30-50cm above canopy during flowering, adjusting based on plant response and environmental conditions.

The Osram Vialox works exceptionally well in hydroponic systems where precise environmental control allows you to maximize the benefits of its intense flowering spectrum. Its consistent output ensures uniform bud development across your entire growing area, making it particularly valuable for commercial operations where consistency is paramount.

Professional Growing Integration

Perfect for experienced growers operating hydroponic and indoor growing systems who understand the importance of spectrum-specific lighting during different plant phases. This flowering-optimized light pairs excellently with metal halide or full-spectrum LEDs during vegetative phases.

Commercial and Hobby Applications

The Osram Vialox NAV-T Super 4Y suits both commercial cultivation facilities and serious hobby growers who demand consistent, high-quality results. Its proven track record in greenhouse and indoor environments makes it a reliable choice for flowering rooms, grow tents, and hydroponic setups. The robust construction handles frequent on-off cycles common in timer-controlled systems while maintaining spectral consistency.

This grow light integrates seamlessly with environmental control systems, responding well to dimming controls and automated lighting schedules. Its high operating temperature makes it suitable for cooler growing environments where additional heat can be beneficial during colder months.

Technical Specifications

Safe Handling and Usage

Protect from shocks and vibrations during installation and operation. Never handle the glass surface with wet or bare hands as oils can cause hot spots and premature failure. Use only with quality ballasts rated for 400W HPS operation. Always follow manufacturer guidelines for safe installation and optimal performance.
