FloraFlex 6-Bar 720W Full Spectrum Under Canopy LED Grow Light

The 720W model delivers exactly double the light output (1944 µmol/s vs 972 µmol/s) and covers twice the area (4' x 8' to 4' x 12' vs 4' x 4' to 4' x 6'). With 6 bars instead of 3, it provides more uniform distribution across larger spaces. Additionally, the 720W model features adjustable power from 100W to 720W, allowing you to scale intensity precisely throughout different growth stages, whereas the 360W operates at a fixed output. The 6-bar configuration also includes 24-inch spacing between bars for flexible positioning.

The wide adjustment range allows you to start at lower intensities during early vegetative growth (100-300W) to avoid overwhelming young plants, then progressively increase power as the canopy develops density. During peak flowering, you can run at full 720W for maximum lower canopy penetration. This adjustability also enables you to fine-tune intensity based on overhead lighting levels, plant genetics, and environmental conditions, optimizing the balance between upper and lower canopy illumination for your specific setup.

The 24-inch spacing provides flexibility to position bars according to your specific canopy structure and plant layout. For uniform canopies, distribute bars evenly across your 4' x 8' to 4' x 12' space. For areas with varying canopy density or plant heights, you can cluster bars closer together in denser zones or spread them wider in more open areas. This adaptability is particularly valuable for mixed-strain grows or tiered canopy structures where light requirements vary across different zones.

Yes, 1944 µmol/s distributed across a 4' x 8' to 4' x 12' area provides substantial supplemental intensity to lower growth sites. Under-canopy lighting doesn't need to match overhead intensity levels—typically 200-400 µmol/s at the lower canopy level is sufficient to significantly improve development. The 720W fixture delivers this target intensity across the specified coverage area, enhancing photosynthetic capacity in previously shaded zones without creating excessive heat or energy consumption at the lower canopy level.

For commercial installations, many growers use adjustable frame systems, cable suspension, or dedicated under-canopy mounting rails that allow height adjustment and easy repositioning. Position the fixture horizontally beneath your canopy at a height that provides adequate coverage without obstructing maintenance access or airflow. The universal 120V-277V input accommodates commercial electrical systems, and the high 0.98 power factor minimizes reactive losses. Consider using multiple 720W fixtures for operations exceeding 4' x 12' footprints, spacing them to maintain consistent intensity across the entire growing area.

Yield improvements from under-canopy supplementation vary based on existing overhead lighting, canopy density, and growing techniques, but many commercial operations report 15-30% yield increases when implementing quality under-canopy systems. The improvement comes from enhanced development of previously shaded lower growth sites that now receive adequate light for full flowering potential. Beyond raw yield increases, growers also report improved material uniformity from top to bottom of the canopy, reducing waste from underdeveloped lower material.

Despite the 720W power level, the passive cooling system effectively manages heat through optimized heat sink design and LED bar distribution that spreads thermal load across the fixture length. The system operates reliably at ambient temperatures up to 95°F (35°C) without fans, maintaining consistent performance while eliminating fan noise and mechanical failure points. The IP65 sealed design also aids thermal management by creating predictable heat dissipation patterns. Ensure adequate air circulation in your growing space to help carry heat away from the fixture.

The 5-year standard warranty covers manufacturing defects and component failures under normal operating conditions, including LED diode failures, driver malfunctions, dimming system issues, 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 beyond IP65 specifications), physical damage, or unauthorized modifications. Always operate within the 120V-277V voltage range and maintain ambient temperatures below 95°F to ensure warranty coverage and optimal performance throughout the fixture's 50,000+ hour lifespan.
