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.

PPFD data for version 2.9 from official datasheet.

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.
