Description

LOADSTAR – Dual Spectrum Lamps

Loadstar Dual Spectrum Lamps provide a powerful, full-spectrum lighting solution for indoor growers. Designed to support both vegetative growth and flowering, these lamps eliminate the need to switch bulbs between growth stages. As a result, they simplify your setup while maintaining optimal plant development.

These lamps work with both metal halide (MH) and high-pressure sodium (HPS) ballasts. Therefore, they offer excellent flexibility for a wide range of grow room systems. Each lamp delivers strong light intensity and reliable performance, helping maximise plant health, structure, and yield.

Available in 250W, 600W, and 1000W options, Loadstar Dual Spectrum Lamps suit everything from small grow tents to large-scale cultivation environments.
