Indoor Sun 250W HPS Pro

Flowering plants rely on specific wavelengths of light to support energy production, floral development, and overall crop performance. A dedicated high-pressure sodium (HPS) lamp provides a warm, red-dominant spectrum suited to the flowering stage, delivering the intensity required for high-demand horticultural applications.

The Indoor Sun 250W HPS Pro is a professional horticultural lamp designed to deliver consistent flowering light output when paired with compatible ballasts. Its 2000K colour temperature provides a spectrum weighted towards red wavelengths, supporting the later stages of the growth cycle where plants require high levels of photosynthetically active radiation.

Delivering a maximum PPF of 400 μmol/s and a lifespan of up to 32,000 hours, the Indoor Sun HPS Pro provides reliable light performance for growers using both electronic and magnetic ballast systems. Its high-intensity output makes it suitable for controlled indoor environments where consistent flowering performance is required.

Compatible with electronic and magnetic ballasts. 250W lamp with a 2000K colour temperature, 34,000 lumen output, and CRI of 25%.
