Sunmaster HPS Vegetative Grow Light Bulb (E40)

Sunmaster HPS Grow Light Bulb — Vegetative Growth, E40 Fitting

Don't let your plants stretch. While most HPS lamps focus purely on the red spectrum for flowering, the Sunmaster Vegetative HPS is optimised to deliver a stronger blue-light spectrum than a standard HPS — the professional's route to dense, bushy vegetative growth without switching to a Metal Halide setup.

Why Choose Sunmaster for Veg:

• Reduced Internodal Stretching: The enhanced blue spectrum keeps plants squat and sturdy, creating more bud sites for the flowering stage.
• Rapid Growth Cycles: Accelerates chlorophyll production for greener, healthier leaves and faster transition times.
• Full Ballast Compatibility: Runs on all magnetic and digital ballasts, no specialised gear required.

Technical Specifications:

• Lamp Type: High-Pressure Sodium (HPS), Vegetative-Optimised
• Fitting: E40 Screw
• Available Wattages: 600W, 1000W
• Compatibility: Digital and magnetic ballasts
• Lifespan: 24,000+ hours (optimal output for the first 10–12 months)

Grower's Tip: Maintain a distance of 18–24 inches (for 600W) from the canopy to prevent heat stress while maximising light penetration. For best results, replace HPS lamps every 9–12 months as PAR output drops off.
