Sunmaster 600W SON-T (Red Spectrum)

A Red-Rich HPS Lamp Built for Bud Fill

The Sunmaster 600W SON-T (Red Spectrum) is a high-output high-pressure sodium lamp weighted towards the red end of the spectrum, the wavelengths plants respond to most strongly in flower. Pushing around 95,000 lumens from a 600W E40 cap, it drops straight into any 600W HID fitting where the priority is dense, well-finished buds rather than leafy vegetative growth.

Fixing light, airy buds that never fill out

Loose, underdeveloped flowers are often down to a spectrum that is too blue or an output too weak for the plant's stage, starving it of the red light needed to trigger strong bud-set. The Sunmaster's red-shifted, high-lumen output gives flowering plants the spectral signal and intensity to pack on density right through to harvest.

Key Benefits

• Red-rich spectrum tuned specifically for flowering and fruiting
• 95,000 lumens of high output for strong canopy penetration on a 600W ballast
• Consistent intensity held across the lamp's working life
• Standard E40 cap - a direct swap into any 600W SON-T fitting
• Durable build for reliable use in professional and hobby grow rooms alike

How to Use

• Fit into a 600W HID fitting and ballast rated for SON-T lamps via the E40 screw cap
• Run once plants are in flower on a 12/12 light cycle
• Hang 30-60cm above the canopy depending on reflector, raising as plants stretch
• Replace after roughly one growing season - HPS output declines with use even while the lamp still strikes
