Grower's Choice AG140 140W Full Spectrum LED Grow Light

Uneven canopy lighting leads to inconsistent flower development and wasted energy on lower-quality buds. The Grower's Choice AG140 eliminates this problem by delivering uniform Vapor Pressure Deficit (VPD) distribution across your entire canopy, resulting in denser flowers and higher yields with 420 µmol/s photon output at just 140W.

The AG140 features a full-phase spectrum optimized for flower production, available in both 3K and red-enhanced options to match your cultivation goals. With an impressive 3.0 µmol/J efficacy rating, this fixture maximizes photosynthetic efficiency while minimizing energy costs. The IP66-rated construction withstands harsh growing environments, resisting IPM sprays and irrigation exposure while remaining easy to clean and maintain.

Installation complexity is eliminated through intelligent design—single-connection power and data chaining allows up to 42 units to operate from one circuit at 480V, dramatically reducing wiring requirements and installation time. The AG140's compact 44.4" × 3.55" × 3.21" form factor and 4.85 lb weight make it ideal for both commercial facilities and space-conscious operations. Backed by a 5-year warranty and L90 50,000-hour lifespan, this fixture delivers professional-grade performance with long-term reliability.

Warranty

The Grower's Choice AG140 is backed by a comprehensive 5-year manufacturer's warranty covering defects in materials and workmanship. With an L90 rating of 50,000 hours, this fixture maintains at least 90% of its initial light output after 50,000 hours of operation, ensuring consistent performance throughout its extended lifespan.

Frequently Asked Questions

How many AG140 units can I daisy chain together? +

The number of units you can daisy chain depends on your input voltage. At 277V, you can connect up to 24 units on a single circuit. At higher voltages, capacity increases: 30 units at 347V and up to 42 units at 480V. This single-connection system eliminates the need for complex wiring and additional electrical infrastructure.

What's the difference between the 3K and red-enhanced spectrum options? +

Both spectrum options deliver full-phase coverage optimized for flowering. The 3K spectrum provides a balanced distribution ideal for general cultivation, while the red-enhanced option increases the ratio of red wavelengths (660-680nm) to further promote flower density and resin production. Both maintain the same 3.0 µmol/J efficacy and 420 µmol/s PPF output.

Can the AG140 withstand high-humidity environments and direct water exposure? +

Yes, the AG140 features an IP66 rating, providing complete protection against dust ingress and powerful water jets from any direction. This rating ensures the fixture can withstand IPM foliar sprays, irrigation overspray, and high-humidity growing environments without compromising performance. The sealed design also makes cleaning and maintenance straightforward.

Do I need to purchase additional cords or accessories? +

Yes, power cords and mounting accessories are sold separately. This allows you to customize your setup based on your facility's specific requirements, including voltage configuration and mounting preferences. The AG140 comes packaged in boxes of 8 units, making it efficient for larger installations while requiring only the accessories needed for your specific application.

How does the 0-10V dimming system work? +

The AG140 uses industry-standard 0-10V dimming control, allowing you to adjust light intensity from 0% to 100% using a compatible controller. This enables you to optimize PAR levels for different growth stages, implement sunrise/sunset routines, or reduce intensity during transplanting or when utilizing the Pro Pod Cloning System. The dimming signal can be sent through the daisy chain connection, controlling all linked fixtures simultaneously.

What coverage area should I expect from each fixture? +

With its 44.4-inch length and 420 µmol/s output, each AG140 is designed for dense, linear coverage ideal for bench-style or vertical farming systems. The uniform VPD distribution technology ensures consistent PAR across the fixture's footprint. For optimal results, consult your facility's specific canopy dimensions and target PPFD levels to determine appropriate spacing between fixtures.

How does the L90 50,000-hour lifespan translate to actual growing time? +

The L90 rating means the fixture maintains at least 90% of its initial light output after 50,000 hours of operation. If you run the lights for 12 hours per day, this translates to over 11 years of use before reaching the L90 threshold. Even at 18 hours per day (common for vegetative growth), you'll achieve approximately 7.6 years of consistent, high-performance lighting covered under the 5-year warranty.

Is the AG140 suitable for vertical farming applications? +

Absolutely. The AG140's compact profile (3.55" × 3.21" cross-section), linear design, and uniform VPD distribution make it ideal for vertical farming racks and multi-tier systems. The IP66 rating provides protection in the high-density, high-humidity conditions typical of vertical farms, while the daisy-chaining capability simplifies installation across multiple growing tiers. Its 140W power consumption also helps manage heat output in densely packed environments.
