Key Features

✔ Dual Spectrum for Veg and Bloom

This lamp blends enhanced blue wavelengths with the classic red HPS output. As a result, it supports healthy vegetative growth while delivering powerful flowering performance.

✔ Strong 400W Light Output

The high-intensity 400W output provides excellent brightness and deep canopy penetration. Therefore, plants grow faster, develop thicker stems, and produce larger, denser flowers.

✔ Ideal for Full-Cycle Growing

Because the bulb works well in both stages, you can use a single lamp from veg to harvest. This keeps your lighting simple, efficient, and cost-effective.

✔ Long-Lasting and Reliable

Sunmaster bulbs are built for consistent output and long service life. This ensures your plants get stable, dependable lighting throughout their entire cycle.

✔ Compatible with All 400W HID Ballasts and Reflectors

It fits standard E40 lamp holders and works with both magnetic and digital ballasts, making installation easy and flexible.
