Eight-bar, full-cycle LED — 2,000 µmol/s at 2.8 µmol/J across a 4×6 footprint.
The Flexstar 720W Pro (4×6) is a foldable eight-bar commercial LED fixture built on Samsung 301B/301H and OSRAM diodes, delivering 2,000 µmol/s PPF at 2.8 µmol/J efficacy with a detachable driver, passive thermal management, and 0-10V dimming — designed to run veg through flower in commercial multi-light rooms without supplemental cooling.
The Flexstar 720W Pro is an eight-bar, foldable full-spectrum LED fixture built specifically for commercial cultivation rooms running continuous cycles. The fixture draws 720W and produces 2,000 µmol/s of photosynthetic photon flux at a rated efficacy of 2.8 µmol/J — a meaningful step up from the 1.7–2.0 µmol/J range typical of double-ended HPS at similar wattage.
Construction centers on Samsung 301B/301H and OSRAM diodes, a diode pairing common in high-tier commercial horticulture LEDs for its combination of broad-spectrum output and long-run bin stability. The driver is detachable, simplifying swap-out without removing the fixture head from the rail — a practical advantage in a room where lights run 18/6 or 12/12 and downtime matters. Passive cooling means no moving parts and no fans to replace or clean.
The 720W Pro 4×6 is sized for licensed cannabis and hemp facilities running dedicated veg and flower rooms in a bench or floor-pot layout. The 4×6 footprint maps cleanly to standard 4-foot-wide rolling bench rows, allowing operators to spec one fixture per bench section and maintain row-to-row uniformity without hotspots.
Operators converting from 1000W DE-HPS will find the 720W Pro delivers comparable canopy-level PPFD at a lower wattage draw — the math on watts-per-square-foot and HVAC load shifts in your favor when you're replacing a room's worth of HPS. The multi-voltage input (120V through 277V) means the fixture integrates into existing commercial electrical infrastructure without rewiring in most cases.
The eight-bar layout folds up to 180 degrees, which matters at installation — the fixture ships compact and opens flat at hang height rather than requiring a crew to manage a rigid wide-body unit. Dimming is handled via 0-10V signal with five discrete output levels (40%, 50%, 60%, 80%, 100%), compatible with standard environmental controllers running 0-10V lighting channels.
IP66 waterproof rating makes the fixture suitable for high-humidity flower rooms and wash-down environments without added enclosure. The 120° light distribution angle, combined with the bar-spread form factor, produces an even PPFD map across the 4×6 target zone with minimal edge drop-off. Passive thermal management — no internal fans — keeps the fixture quiet, reduces maintenance touchpoints, and contributes to the fixture's 5-year warranty coverage.
For room designers, the 720W Pro 4×6 is straightforward to lay out: one fixture per 4×6 zone, hung at manufacturer-recommended height (minimum 6 inches above canopy), with 0-10V daisy-chaining across a controller for zone-level intensity adjustments during veg, transition, and peak flower. The detachable driver can be mounted off the fixture — on a wall bracket or truss arm — to reduce canopy heat load where the thermal budget is tight.
The 277V input option is particularly relevant for large rooms already wired for 277V commercial circuits, as it reduces amperage draw per circuit and allows more fixtures per breaker. At 277V input the 720W Pro draws 2.6A, which means a 20A commercial circuit can support up to seven fixtures before hitting the 80% NEC load rule — useful when planning circuit counts for a 20-fixture or 40-fixture room build.

It is a full-cycle fixture. The Samsung 301B/301H and OSRAM diode combination produces a broad full spectrum suitable from early veg through late flower. The five-step 0-10V dimming lets you dial intensity up or down to match the DLI target for each stage rather than running the fixture at 100% during propagation or early veg.
Yes. The 720W Pro accepts 120V, 208V, 240V, and 277V input. At 277V it draws 2.6A, making it compatible with standard commercial lighting circuits and reducing the amperage load per circuit compared to lower-voltage operation.
Passive cooling on bar-style LEDs is effective when room HVAC is sized correctly for the heat load — the fixture relies on ambient airflow rather than internal fans. The IP66 rating and 5-year warranty reflect Flexstar's confidence in the thermal design under commercial operating conditions. If your room runs consistently above 85°F ambient, ensure your HVAC can handle the combined fixture load before eliminating active cooling from the fixture spec.
At 277V the fixture draws 2.6A. The NEC 80% continuous load rule limits a 20A circuit to 16A continuous. That gives you six fixtures per circuit at 15.6A total draw, staying within the 80% rule. Always confirm circuit sizing with your licensed electrician against your specific facility's wiring.
