Philips Master GreenPower CG 400W HPS Bulb

Professional HPS Technology for Flowering Excellence

The Philips Master GreenPower CG 400W HPS bulb represents decades of horticultural lighting expertise, specifically engineered for indoor plant cultivation with emphasis on flowering performance. This high-pressure sodium lamp delivers an optimized light spectrum that promotes vigorous flowering while maintaining enough blue light content for full-cycle growing applications. Developed by Philips' agricultural lighting division, this bulb incorporates advanced phosphor coatings and precision engineering to maximize photosynthetic efficiency and crop yields.

Superior Spectral Output and Performance

The Master GreenPower CG 400W produces an impressive 60,000 lumens with a photosynthetic photon flux of 850 micromol/s, delivering exceptional light intensity for robust plant development. The carefully balanced spectrum emphasizes red-yellow wavelengths crucial for flowering while incorporating enhanced blue-white light that supports vegetative growth, making this a versatile full-cycle growing solution.

• 60,000 lumen output - maximum light intensity for vigorous plant growth
• 850 micromol/s PAR output - optimized photosynthetic photon flux
• 2000K color temperature - ideal red-yellow spectrum for flowering
• Enhanced blue content - supports full-cycle cultivation applications
• 32,000-hour lifespan - exceptional longevity reduces replacement costs
• Universal E40 socket - compatible with all standard ballasts
• Dual orientation capability - horizontal and vertical installation options
• A+ energy efficiency - maximizes light output per watt consumed

Installation and Operating Guidelines

The Master GreenPower CG 400W features universal compatibility with both conventional magnetic ballasts and modern electronic ballasts, providing flexibility for various lighting systems. The standard E40 socket ensures easy installation in most reflector housings, while the dual orientation capability allows both horizontal and vertical mounting depending on your growing setup requirements.

This HPS bulb excels in flowering applications where red-yellow spectrum dominance promotes robust bud development and resin production. However, the enhanced blue light content makes it suitable for full-cycle growing, eliminating the need for bulb changes between vegetative and flowering phases. The 283x47mm dimensions fit standard reflector housings while the lightweight 182g construction minimizes stress on mounting systems.

Proper handling is essential for maximum lifespan and safety. Never touch the glass envelope with bare hands, as skin oils can create hot spots leading to premature failure. Always allow adequate cooling time between power cycles, and ensure your ballast matches the 400W rating. The maximum operating temperatures are 450°C for the bulb envelope and 240°C for the base, requiring adequate ventilation in enclosed fixtures.

Ideal for Serious Indoor Cultivators

This professional-grade HPS bulb targets experienced growers who demand consistent, high-quality light output for their flowering phases. Commercial cultivation operations, serious hobbyists with established growing systems, and anyone prioritizing maximum yields will appreciate the Master GreenPower's performance characteristics. The 32,000-hour lifespan provides exceptional value for continuous operation scenarios.

The bulb's versatility makes it suitable for various growing methods including soil, hydroponic, and aeroponic systems. Pair with quality reflectors and proper ventilation for optimal results. Remember that HPS bulbs generate significant heat, requiring adequate cooling and climate control in your growing environment.
