Description

L3 linear LED grow lights

OVERVIEW

The QL-L3 series linear LED grow lights are designed for high-density commercial cultivation, providing up to 1296 µmol/s of photosynthetically active radiation (PPF) and an industry-leading photon efficiency of 2.7 µmol/J. The L3 series is available in 240W and 480W power configurations, covering a wide spectral range of 370–730nm, optimized for both vegetative growth and flowering stages of plants.

The QL-L3 features 0–10V/PWM dimming, universal voltage (100–480VAC), and a robust aluminum housing (1030×81×56mm), ensuring reliable operation even in harsh environments. With a driver life of up to 50,000 hours (L90 > 36,000 hours) and an optional IP65 protection rating, it is ideal for vertical farms, greenhouses, and medical cannabis cultivation facilities.

Spectral Options:

Full-Sunlight Spectrum: Broadband white light (380–730 nm) combining 6000K (cool white) and 3000K (warm white) LEDs, closely mimicking natural daylight with enhanced red and far-red continuity. CRI >90, suitable for full-cycle plant growth.
Targeted Red-Blue (RB) Blend: Optimized ratio of 60% deep red (660 nm) + 40% blue (450 nm) for vegetative vigor and compact morphology; ideal for seedling, propagation, or energy-efficient supplemental lighting.
Advanced Full-Spectrum + FR: Full-sunlight base with added far-red (730 nm) for photomorphogenic control (shade avoidance, flowering acceleration) – available on select models.
All above are standard configurations. Custom spectral recipes (e.g., 70/30 RB, UV inclusion, tunable white, or multi-channel control) are available upon request for commercial or research applications.
