FloraFlex Far Red Retrofit Bars | 2-Pack

Far-red light (700-750nm) triggers photomorphogenic responses that can enhance flowering, increase stem elongation, and improve overall material quality. Research shows that far-red supplementation can accelerate flowering transitions and increase flower biomass, especially when used alongside FloraFlex Full Tilt: Late Bloom Ripener. These retrofit bars allow you to add this beneficial spectrum to your existing lighting system without a complete fixture replacement.

The FloraFlex Far Red Retrofit Bars are designed to supplement most LED grow light systems. They require a compatible 51V DC power supply (sold separately) and physical mounting capability near your existing fixtures. The bars work best when positioned to provide even far-red coverage across your canopy, typically mounted alongside or between your primary light bars. Check your existing fixture's specifications to ensure compatibility and adequate mounting options.

IP65 certification means the bars are completely protected against dust ingress and can withstand water jets from any direction without damage. This makes them suitable for high-humidity environments, areas with foliar spraying, or spaces where condensation may occur. However, the bars should not be submerged in water or exposed to direct continuous water streams beyond typical misting or spray exposure.

At 3.3 µmol/J efficacy, these retrofit bars rank among the most efficient far-red supplementation products available. This means they produce 3.3 micromoles of far-red photons for every joule of electricity consumed, delivering substantial output while drawing only 87.5W combined for both bars. The use of premium Osram 6.24 diodes ensures this efficiency is maintained throughout the bars' operational lifespan.

Yes, you'll need a compatible 51V DC power supply capable of delivering at least 87.5W to power both bars. The bars do not include a power supply, as this allows you to select the appropriate driver for your specific installation needs. You may also need mounting hardware like the FloraFlex Magnetic Light Hanger depending on your existing fixture configuration. Consider whether you want the bars on a separate timer or controller for precise far-red scheduling.

Far-red supplementation strategies vary based on cultivation goals. Some growers run far-red throughout the entire photoperiod to maximize the Emerson enhancement effect, while others use it only during the final hours of the light period or during flowering stages. A common approach is providing 15-30 minutes of far-red at the end of each photoperiod to accelerate the transition to the "night" state. Experiment with timing to find what works best for your specific material and growing conditions.

Mounting options depend on your existing fixture design. Many growers mount the bars parallel to their main light bars using the FloraFlex Adjustable Rope Ratchet Pulley System for secure placement. Others attach them directly to the fixture frame if mounting points are available. Ensure the bars are positioned to provide even coverage across your canopy and that all electrical connections are secure. The lightweight design makes them easy to integrate without significantly affecting your fixture's weight distribution.

The 5-year limited warranty covers manufacturing defects and component failures under normal operating conditions, including LED failures and electrical component malfunctions. The warranty typically excludes damage from improper installation, operation outside specified parameters (such as exceeding 95°F ambient temperature), physical damage, water damage beyond the IP65 rating, or use with incompatible power supplies. Always operate within the specified 51V DC input requirements and maintain ambient temperatures below 95°F to ensure warranty coverage.
