Description

L1 linear LED grow lights

High-Efficiency Linear LED Grow Lights for Medium to Large-Scale Agriculture

Overview

The L1 series elongated plant grow lights feature a high-power integrated structure, specifically designed for medium to large-scale agricultural facilities. The integrated molding process eliminates complex installation steps, allowing for rapid deployment in high-density planting environments such as plant factories, greenhouses, and vertical farms.

Through precise red-blue spectrum matching or a combination of high color rendering white light (3000K/6000K), photosynthetic efficiency is effectively improved, with a maximum PPF output of 435 μmol/s and a stable PPF/W energy efficiency of 2.9 μmol/J. Balancing high output with low energy consumption, it is an ideal choice for large-scale smart agricultural lighting.

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.
