Iluminar Under Canopy 160W Full Spectrum LED Grow Light

Dense canopies blocking light from reaching your lower buds? You're leaving yield on the table.

The Iluminar Under Canopy 160W LED Grow Light solves this problem by delivering targeted supplemental lighting exactly where your plants need it most—the lower canopy.

Designed for serious indoor growers, this high-efficiency under-canopy light ensures every leaf and bud receives the photons needed to thrive. Available in two optimized spectrum options—Full Spectrum (FS) for HPS/DE-HPS systems and Red-focused (R) for LED setups—this light integrates seamlessly with your existing top lighting to maximize lower flower development and overall yield.

With an impressive 2.8-3.0 µmol/J photon efficacy, the Under Canopy Light delivers powerful results while keeping energy costs in check. The FS model enhances photosynthesis, terpene production, and plant health with optimized yellow and green wavelengths. The R model supplements full spectrum LED systems with concentrated red wavelengths critical for photosynthesis and crop development.

Built for commercial environments, this light features IP65-rated water resistance for reliable performance in high-humidity conditions. The included 0-10V dimming gives you complete control over light intensity throughout all growth stages. Backed by a 5-year warranty, you're investing in long-term reliability and peace of mind.

FAQs

Which spectrum should I choose for my grow setup? +

Choose the FS (Full Spectrum) model if you're using HPS or DE-HPS top lighting systems. The FS spectrum adds yellow and green wavelengths that complement HPS lighting and enhance photosynthesis, plant health, and terpene development. Choose the R (Red) spectrum model if you're using full spectrum LED top lights. The R spectrum provides concentrated red wavelengths that supplement your LED system and maximize under-canopy photosynthetic efficiency.

How many Under Canopy lights do I need for my grow space? +

The number of lights depends on your canopy density, plant spacing, and desired coverage. Each light measures 45.3 inches (1150mm) in length and provides a 120° light distribution angle. For optimal results, position lights to ensure even coverage across lower canopy areas. Most growers install one light per row or between plant rows for maximum penetration.

Can I dim the Under Canopy 160W light? +

Yes, the Under Canopy 160W features 0-10V dimming capability, giving you complete control over light intensity. This allows you to adjust output based on growth stages, plant response, or environmental conditions. You'll need a compatible 0-10V dimming controller to use this feature.

Is the Iluminar Under Canopy light suitable for high-humidity environments? +

Absolutely. The Under Canopy 160W is rated IP65 for water resistance, making it ideal for high-humidity grow environments. This rating means the light is protected against water jets and dust ingress, ensuring reliable performance even in challenging conditions.

How do I install the Under Canopy light? +

Each light includes a support stand for easy installation. Position the lights horizontally beneath your canopy, between plant rows or along the sides of your growing area. The included stand allows for stable placement at the optimal height. For detailed installation instructions, refer to the user manual included with your purchase.

What voltage does the Under Canopy 160W operate on? +

The Under Canopy 160W operates on 120-277V AC, making it compatible with most North American electrical systems. It automatically adjusts to your input voltage with the following current draw: 120V (1.33A), 208V (0.77A), 220V (0.73A), or 277V (0.58A).

How does under-canopy lighting improve yields? +

Under-canopy lighting addresses the common problem of light penetration in dense canopies. Top lighting often can't reach lower leaves and bud sites, resulting in underdeveloped lower flowers. By providing direct supplemental light to these areas, the Under Canopy 160W stimulates photosynthesis throughout the entire plant, improving lower bud development, density, and overall yield quality.

What is the expected lifespan of this light? +

The LEDs in the Under Canopy 160W are rated for 50,000 hours of operation. With typical usage of 12-18 hours per day, this translates to approximately 7-11 years of reliable performance. The light is backed by Iluminar's 5-year warranty for added peace of mind.
