LED Bar 3x36W 108W Cultivation Growth Plants culture growing

115 cm LED Grow Light Bar for Indoor Cultivation and Greenhouses

The 115 cm full spectrum LED grow bar is engineered to deliver optimal lighting for plants throughout the entire vegetative cycle, from germination to flowering. With its balanced light spectrum and high energy efficiency, it is the ideal solution for greenhouses, grow tents, indoor farms and professional hydroponic systems.

Light spectrum optimised for photosynthesis

Plants respond selectively to different wavelengths of visible light. Chlorophyll photosynthesis mainly occurs within the 400-700 nm range (PAR radiation). Our LED bar uses a precisely calibrated colour ratio designed to stimulate vegetative growth, flowering and fruiting:

• 24 red LEDs — for flowering and fruiting stages
• 6 blue LEDs — for vegetative growth and foliage development
• 2 green LEDs — for light penetration into the lower canopy
• 4 infrared LEDs (IR) — for phytochrome recycling

Total: 36 LED chips per bar, evenly distributed to ensure uniform light output along the full length.

Key wavelengths for plant cultivation

• 439 nm — chlorophyll A absorption peak (blue)
• 450-460 nm — royal blue, beta-carotene absorption peak
• 469 nm — chlorophyll B absorption peak
• 525 nm — green light, phototropic activator
• 590 nm — carotenoid and phycoerythrin absorption
• 625 nm — phycocyanin absorption peak
• 660 nm — super-red, essential for flowering
• 730 nm — far-red for phytochrome recycling

Technical and build specifications

• Aluminium housing with high thermal dissipation for LED cooling and extended lifespan
• Estimated lifespan: 50,000 hours of operation
• IP65 protection rating — bar, driver and connectors waterproof and dustproof
• Epistar / Ledstar LED chips, market leaders for luminous efficiency and reliability
• Length: 115 cm — ideal for racks and grow tunnels
• CE, ROHS and FCC certified

Recommended applications

The LED grow bar is suitable for professional greenhouses, nurseries, indoor farming, grow tents, hydroponic and aeroponic systems, leafy vegetables, aromatic herbs, ornamental and medicinal plants. The installation height should be set according to the cultivated species and growth stage to achieve optimal yield.

Why choose LED lighting for cultivation

Compared to traditional HPS or fluorescent lamps, LED technology allows you to precisely select the wavelengths most effective for photosynthesis, cutting energy consumption by up to 60% and eliminating the excessive heat that can damage crops. Plants receive only the light they truly need, with significant savings on energy bills and richer harvests.
