LED Grow Light Cultilite Phoenix 720W: Power and Efficiency for Indoor Cultivation

p>Cultilite PHOENIX 720W LED Grow Light: Cultilite’s answer to professional LEDs at an affordable price. Designed to evenly cover a growbox of about 120 × 120 cm, it combines high efficiency, 0–10V control, and reliability for serious setups.

The Sanan diodes (4000K + 660 nm) are now a mature, high-performance choice: once considered less known than Samsung, today they deliver equivalent quality in horticultural applications, with excellent photosynthetic output and durability.

Available versions

• Phoenix 720W – 2.9 µmol/J (PPF 2088 µmol/s).
• Phoenix 720W – 3.2 µmol/J (PPF 2304 µmol/s).

Why choose it

• Real efficiency up to 3.2 µmol/J to maximize grams per watt.
• Full spectrum 4000K + 660 nm for compact veg and abundant, high-quality bloom.
• Uniform coverage optimized for 1.2 × 1.2 m with high PPFD even at the edges.
• Control 0–10V/PWM dimming and daisy-chain up to 50 fixtures via RJ11.
• Reliability IP65 rating, passive cooling, 50,000 h lifetime.

Recommended use

• 120 × 120 cm growbox: one Phoenix for full coverage, 15–35 cm above canopy in flowering depending on strain.
• Humid/dusty environments: IP65 and passive cooling ensure stable performance.
• Dimming: adjust intensity and DLI according to growth stage and VPD.

Note: PPFD values come from tests on a 1.2 × 1.2 m area and are useful for comparison and planning. In real setups, results vary depending on reflections, hanging height, canopy density, and layout.
