Lumatek Dual 400W 240V HPS Grow Lamp, 55,000 lm

Lumatek Dual 400W 240V HPS Lamp for Powerful Plant Growth

The Lumatek Dual 400W 240V HPS Lamp is a high-performance horticultural light source designed for growers who want reliable results, strong output, and stable performance throughout the entire growth cycle. Built for use with a compatible 400W electronic ballast, this high pressure sodium (HPS) lamp delivers an optimal light spectrum for healthy plant development, making it a dependable choice for both vegetative and flowering stages.

Engineered for HPS and MH Growing Systems

This 400W bulb is designed for use with an HPS/MH power supply of the same wattage, ensuring proper operation and consistent lighting performance. The 240V configuration makes it suitable for compatible grow room installations where stable voltage and efficient power delivery are required. Whether you are upgrading an existing setup or replacing a worn bulb, this lamp is made to integrate seamlessly with professional horticultural systems.

Full Spectrum Support for the Entire Plant Lifecycle

One of the key advantages of this lamp is its full-cycle spectrum, often described as suitable for both growth phases. The spectral output has been developed to support vigorous plant development, helping promote strong structure during vegetative growth and encouraging productive flowering later on. With a color temperature of 2050K, this HPS lamp provides the warm light quality typically associated with high-yield indoor cultivation.

High Luminous Output for Efficient Indoor Cultivation

With a luminous output of 55,000 lumens, the Lumatek Dual 400W lamp is built to deliver intense illumination for indoor growing environments. High brightness is essential for maximizing light penetration and supporting healthy photosynthesis, especially in grow rooms where dependable light intensity can directly influence crop quality and yield potential. This makes the lamp a strong choice for growers seeking efficient, practical lighting performance.

Pulse-Start Technology for Faster Ignition and Better Lamp Life

This HPS lamp uses pulse-start technology, which helps provide faster start-up and quicker restrike time compared to conventional solutions. Faster ignition can improve usability in controlled grow environments, while the advanced design also supports longer service life and better lumen maintenance over time. This means the lamp is designed not only for strong performance, but also for lasting value.

Ceramic Arc Tube Construction for Stability and Durability

The lamp features high-grade ceramic arc tube technology, a construction method that helps the bulb operate at higher internal temperatures while maintaining excellent efficiency and color consistency. The PCA ceramic arc tube resists chemical interaction inside the bulb, helping stabilize the gas mixture throughout the lamp’s lifespan. This contributes to more consistent light quality, better output retention, and improved long-term performance.

Optimized PAR and PPF Maintenance

For growers focused on plant development rather than just brightness, this lamp offers another important advantage: stable PAR/PPF maintenance. Reliable photosynthetically active radiation is essential for supporting plant growth, and the Lumatek Dual 400W has been engineered to maintain strong output over time. That makes it especially attractive for indoor growers who want dependable light efficiency throughout the life of the lamp.

Durable 400W HPS Lamp with Long Service Life

Designed as a 400W sodium lamp, this model combines strong horticultural performance with a rated service life of 28,000 hours. Long service life helps reduce replacement frequency and supports better operating efficiency in professional and hobby grow setups alike. When paired with the correct ballast and installed properly, this lamp can provide consistent horticultural lighting for an extended period.

E40 Base for Standard Compatibility

The lamp is equipped with an E40 thread, a widely used fitting in horticultural lighting systems. This standard base helps ensure straightforward installation in compatible fixtures and grow light setups. The combination of the E40 socket, 400W power rating, and 240V design makes this lamp a practical and versatile choice for indoor cultivation systems.
