The Hortitek ECO R Underlight 140W is your solution to boosting canopy penetration and lower-tier growth. Designed specifically to be placed under the canopy, this powerful supplemental LED grow light delivers targeted lighting where your main fixtures can’t reach—promoting healthier foliage and stronger flower development all the way down the plant.

With an ultra-wide 150° beam angle, high PPF output of up to 406μmol/s, and efficacy of 3.3μmol/J, this light ensures deep, even distribution—perfect for increasing yield potential in any professional grow setup.

Features

Optimised Under-Canopy Illumination
Target the often-neglected lower areas of your plants. With its 150° wide beam angle, the ECO R Underlight ensures that every inch of your canopy receives the light it needs to thrive.

High-Efficiency Output
Delivers a powerful PPF of up to 406μmol/s and up to 3.3μmol/J efficacy, ensuring your plants get maximum usable light without wasting energy.

Passive Cooling System
No noisy fans here. The fixture uses a passive thermal management system that keeps temperatures low and performance high—even in tightly packed environments.

Power & Signal Daisy-Chaining
Connect up to 12 units seamlessly with power and signal chaining. Easily scale your lighting setup without complicated wiring.

Full Dimming Control
Compatible with 0-9V LED dimming controllers, allowing you to dial in the perfect intensity throughout the growth cycle.

Built to Last
With an IP66 rating, the ECO R Underlight is dust-tight and water-resistant—ready to handle the toughest grow room conditions.

Compact & Flexible
Comes with an adjustable stand for perfect placement beneath any canopy layer, regardless of grow space size or configuration.
