FLEXSTAR 720W Pro 4*4

What It Is

The Flexstar 720W Pro 4×4 (SKU 307127-4*4) is a commercial-grade, eight-bar foldable LED fixture from Flexstar's Pro Series — a full-cycle line purpose-built for licensed indoor cannabis and hemp production. The fixture draws a true 720 watts and produces 2000 µmol/s total PPF at a rated efficacy of 2.8 µmol/J, using a diode package built on Samsung and OSRAM LEDs for a full-spectrum output calibrated to support photosynthesis across every growth stage.

The eight-bar form factor folds up to 180 degrees, which simplifies installation in tight vertical racking configurations and reduces shipping volume. There is no active cooling — no fans to fail, no noise, no moving parts. Passive heat dissipation through the aluminum bar chassis keeps operating temperatures stable and contributes to the rated L90 lifespan of greater than 54,000 hours. The detachable driver further simplifies service and heat management in sealed or climate-sensitive room builds.

Who It's Built For

This fixture fits licensed cannabis and hemp operators running multi-light commercial rooms who need a consistent, spec-able fixture they can replicate across a build without chasing variable performance. The 4×4 coverage footprint makes it a direct match for standard 4-foot-wide rolling bench or fixed-bench runs, and the five-step dimming (40 / 50 / 60 / 80 / 100%) lets cultivation directors dial intensity by stage without swapping hardware.

Operators retrofitting away from double-ended HPS will find the wattage class familiar while gaining measurable energy efficiency. The 277V input compatibility means this fixture integrates directly into commercial electrical infrastructure without step-down transformers — a practical requirement for any multi-light room on a 277V or 480V three-phase service. Multi-light rooms can leverage the 0-10V control interface for zone-level dimming through compatible environmental controllers.

Key Features

Samsung and OSRAM diodes deliver a full-spectrum output covering the PAR range from seedling through late flower. IP66 ingress protection means the fixture handles wash-down environments, high-humidity flowering rooms, and the cleaning cycles that compliance-focused operations run between harvests — no bagging fixtures before sanitation.

Five discrete dimming steps (40%, 50%, 60%, 80%, 100%) via the 0-10V interface give head growers repeatable, documented intensity settings by stage — important for compliance grows that log environmental parameters. The foldable eight-bar design deploys flat or angled and mounts on standard grow room racking systems. Net fixture weight for the 4×4 configuration is 32.6 lbs, manageable for a two-person install team without specialty rigging equipment. A 5-year manufacturer warranty covers the fixture.

How It Fits a Commercial Build

In a single-tier or multi-tier commercial room, one 720W Pro 4×4 covers a 4×4 canopy zone. For a standard 1,000-square-foot flowering room, a uniform grid of fixtures — each covering 16 sq ft — delivers consistent PPFD across the canopy without the hotspot patterns that come from HID point-source lighting. The passive design removes the noise and maintenance overhead of fan-cooled fixtures, which matters in tightly packed multi-tier configurations where airflow is already managed at the room level.

The detachable driver allows the heat-generating component to be positioned outside the canopy zone or on the fixture frame rail, keeping radiant heat off the plants. For facilities running 277V three-phase distribution — typical in purpose-built cultivation buildings — the Flexstar 720W Pro connects natively without additional electrical hardware. Operators scaling to multiple rooms can standardize on this fixture class across the build for uniform light plans, consistent PPFD targets, and simplified spare-parts management.
