FloraFlex 3-Bar 360W Full Spectrum Under Canopy LED Grow Light

Under-canopy lighting addresses one of the most common yield limitations: light penetration to lower growth sites. Upper canopy foliage naturally shades lower branches, reducing photosynthetic capacity and resulting in smaller, lower-quality material in these zones. By providing direct illumination to the lower canopy with 972 µmol/s output, this fixture enables these previously shaded sites to develop fully, significantly increasing total yield per square foot and improving overall material uniformity from top to bottom.

The 3-bar design distributes light sources across the fixture width, creating more uniform coverage compared to single-bar configurations. This arrangement ensures light reaches between plant stems and under foliage more effectively, with the 120-degree beam angle from each bar overlapping to eliminate shadows. The configuration is specifically optimized for 4' x 4' to 4' x 6' spaces, matching common growing area dimensions for seamless integration into existing setups.

Osram red diodes are premium LED components known for efficiency and spectral precision in the red wavelengths crucial for flowering and fruiting responses. For under-canopy applications, red spectrum is particularly valuable because it penetrates foliage more effectively than blue wavelengths and directly stimulates the photosynthetic and photomorphogenic processes that drive flower development. The combination of Osram reds with full-spectrum top-brand chips provides both the penetration power and complete spectral balance needed for optimal lower canopy productivity.

Position the fixture horizontally beneath your canopy, typically at a height that allows light to reach the lower third of your plants without obstructing airflow or maintenance access. The fixture should be centered in your 4' x 4' to 4' x 6' space for optimal coverage. Many growers mount under-canopy lights on adjustable stands or frame systems that allow height modifications as plants develop. Ensure adequate clearance for heat dissipation despite the passive cooling system, and avoid placing the fixture so low that it creates excessive heat stress on lower foliage.

IP65 certification means the fixture is completely sealed against dust ingress (the "6") and protected against water jets from any direction (the "5"). This is particularly important for under-canopy applications where the fixture is closer to the growing medium and more likely to encounter water from irrigation, runoff, or foliar applications. The sealed construction protects sensitive electronics while operating in the high-humidity conditions common beneath dense canopies, ensuring reliable long-term performance without moisture-related failures.

The high power factor (0.97-0.99 depending on voltage) means the fixture converts electricity into usable light very efficiently with minimal wasted energy. Power factor represents the ratio of real power doing work versus apparent power drawn from the circuit. At 0.99, virtually all the electricity drawn is converted to useful output rather than wasted as heat or reactive losses. This high efficiency reduces your electricity bills and allows you to run more fixtures on a single circuit compared to lower power factor alternatives.

While this fixture delivers substantial light output (972 µmol/s), it's specifically engineered and optimized for under-canopy supplementation rather than primary overhead lighting. The 3-bar configuration, mounting design, and coverage pattern are intended to work in conjunction with overhead fixtures to create a complete lighting strategy. For best results, use this as supplemental under-canopy lighting beneath higher-wattage overhead fixtures that provide primary illumination to the upper canopy.

The 5-year standard warranty covers manufacturing defects and component failures under normal operating conditions, including LED diode failures, driver malfunctions, and housing defects. The warranty typically excludes damage from improper installation, operation outside specified parameters (such as exceeding 95°F ambient temperature or exposing the fixture to water pressure beyond IP65 specifications), physical damage, or unauthorized modifications. Always operate within the specified voltage range (120V-277V) and maintain ambient temperatures below 95°F to ensure warranty coverage and optimal performance.
