Plantmax HPS T46 E40 – High Performance Flowering Lamp

The Plantmax HPS T46 E40 is a premium High Pressure Sodium (HPS) grow lamp engineered to deliver outstanding performance during the flowering stage of plant growth. Designed for growers who demand reliable light output and excellent flowering results, the Plantmax HPS produces a powerful 2000 Kelvin red and orange-rich spectrum that encourages abundant flower development, improved fruit production and increased yields.

Available in 400W and 600W models, the Plantmax HPS T46 is ideal for indoor grow tents, hydroponic systems and commercial grow rooms. The warm spectrum closely matches the wavelengths plants naturally require during bloom, helping stimulate flowering hormones while promoting larger, denser flowers and more vigorous crop production.

Built using high-quality components, the Plantmax lamp delivers excellent light output with high PAR (Photosynthetically Active Radiation) efficiency, ensuring more usable light reaches the plant canopy where it is needed most. Its efficient design helps maximise photosynthesis while maintaining dependable performance throughout the lamp’s operating life.

The Plantmax HPS features a standard E40 mogul base, making installation quick and straightforward into compatible HPS reflectors and lamp holders. It is designed for use with single-ended 400W or 600W HPS ballasts, depending on the selected lamp wattage.

Whether you’re growing flowering ornamentals, fruiting vegetables or other high-light crops, the Plantmax HPS T46 provides the proven performance growers have relied on for years. Combining strong light output, reliable operation and an optimised flowering spectrum, it remains one of the most popular HPS lamps for indoor cultivation.

For best performance, many growers replace HPS lamps after approximately 9–12 months of regular use, as light output gradually decreases over time, even though the lamp may continue to operate.
