Osram NAV-T SUPER 4Y 250W-Flower

Premium High-Pressure Sodium Lighting for Flowering Stage

The Osram NAV-T SUPER 4Y 250W represents the pinnacle of high-pressure sodium (HPS) lighting technology for indoor plant cultivation. Specifically engineered for the flowering phase of plant development, this clear tubular bulb delivers exceptional performance and reliability. As part of Osram's renowned VIALOX® NAV®-T SUPER 4Y® series, this lamp stands among the brightest and most energy-efficient sodium discharge lamps available to indoor growers today.

Key Features and Benefits

This professional-grade HPS bulb combines cutting-edge German engineering with practical growing requirements, making it an essential component for serious indoor cultivation setups.

• Exceptional luminous output of 33,200 Lm ensures maximum light penetration through plant canopy
• Optimized 2000K color temperature provides ideal red spectrum for flowering and fruiting phases
• Clear tubular design maximizes light transmission without phosphor coating interference
• Standard E40 socket compatibility fits most commercial reflectors and ballasts
• Energy-efficient 250W power consumption delivers outstanding lumen-per-watt ratio
• Compact 257 x 46 mm dimensions suitable for smaller grow spaces and tent setups
• Long-lasting construction reduces replacement frequency and maintenance costs

Application and Growing Performance

The NAV-T SUPER 4Y 250W excels during the critical flowering period when plants require intense, warm-spectrum lighting to develop dense, resinous flowers. The 2000K color temperature provides the red and far-red wavelengths that trigger and sustain flowering hormones, while the high photon density ensures deep light penetration even in multi-level canopies.

This lamp works exceptionally well in grow tents, small grow rooms, and hydroponic systems where space efficiency is crucial. The 250W power rating makes it ideal for 2x2 to 3x3 foot growing areas, providing sufficient intensity for 2-4 medium-sized flowering plants. When paired with a quality reflector and magnetic or electronic ballast, growers can expect vigorous flower development and enhanced essential oil production.

For optimal results, maintain the lamp 12-18 inches from plant canopies, adjusting distance based on plant response and heat management. The clear bulb design allows for excellent heat dissipation when used with proper ventilation systems.

Ideal for Professional and Home Cultivators

This Osram HPS lamp caters to both commercial operations and dedicated home growers who demand professional-quality results. It's particularly suitable for cultivators transitioning from vegetative to flowering phases, those running perpetual harvest systems, and growers seeking to maximize flower density and potency.

The lamp pairs excellently with hydroponic growing systems where precise environmental control enhances the benefits of quality lighting. Consider combining with proper climate control equipment and ventilation systems available in our complete hydroponics and indoor growing category for optimal results.
