Designed for growers who need consistent, high-intensity output from a proven HPS source.\u003c\/p\u003e\n\u003ch2\u003ePerformance Benefits\u003c\/h2\u003e\n\u003ch3\u003eChlorophyll Production \u0026amp; Photosynthetic Efficiency\u003c\/h3\u003e\n\u003cp\u003eThe red\/orange spectrum (550–700nm) directly stimulates chlorophyll absorption, improving photosynthetic rate and overall plant health throughout the flowering cycle. More efficient photosynthesis translates to faster development and heavier final yields.\u003c\/p\u003e\n\u003ch3\u003eStem Strength \u0026amp; Plant Structure\u003c\/h3\u003e\n\u003cp\u003eHigh-intensity HPS output promotes thicker primary stems and more compact internode development — reducing stretch, improving structural support, and producing a more productive canopy architecture from early flower through to late bloom.\u003c\/p\u003e\n\u003ch3\u003eEarlier Flowering Induction\u003c\/h3\u003e\n\u003cp\u003eThe Sunmaster spectrum accelerates the transition into the bloom phase, reducing the time between light cycle change and visible flower development. Earlier flowering means shorter overall cycle times and more runs per year.\u003c\/p\u003e\n\u003ch3\u003eIncreased Yield Potential\u003c\/h3\u003e\n\u003cp\u003eLarger leaf mass, stronger stems, earlier flowering, and improved canopy penetration combine to drive heavier, denser harvests. The Sunmaster spectrum is tuned specifically for this outcome — not a general-purpose lamp adapted for horticulture.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e High Pressure Sodium (HPS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Flowering \/ Bloom phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Requires HPS ballast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sunmaster\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSunmaster vs Philips SON-T — which HPS bulb is better for flowering?\u003c\/h2\u003e\n\u003cp\u003eBoth are proven commercial HPS lamps.
