FLEXSTAR 430W Pro

What It Is

The Flexstar 430W Pro is an eight-bar, foldable full-spectrum LED fixture from Flexstar's Pro Series — their commercial full-cycle line. At 430 watts true draw, it produces 1,200 µmol/s of photosynthetic photon flux with a photon efficacy of 2.8 µmol/J. That output-per-watt ratio puts it in the same conversation as the top-tier bar-style LEDs on the market today.

Diodes are Samsung 301B and 301H combined with OSRAM deep-red emitters — a proven dual-source configuration that spans the full photosynthetically active spectrum. The driver is detachable, simplifying heat management and enabling clean ceiling mounts in rooms with tight vertical clearance. Thermal management is entirely passive: no fans, no moving parts, no noise, and no mechanical failure points in the cooling system.

The bars fold to 180 degrees, which reduces shipping volume and makes fixture handling and repositioning inside a room significantly easier. At 29.43 lb, it's manageable for a two-person hang crew without rigging equipment.

Who It's Built For

Licensed cannabis and hemp operators running commercial indoor rooms who want to step off double-ended HPS or CMH without giving up light intensity. At 2.8 µmol/J, the 430W Pro delivers the photon output per watt that makes the HID-to-LED transition operationally sound — not just a marketing claim.

It's a strong fit for multi-tier vertical grow configurations. The foldable eight-bar form factor and detachable driver give you flexibility in mounting geometry that a rigid single-panel fixture doesn't. IP66 waterproofing makes it appropriate for humid flower environments and wet-clean facilities. Operators running perpetual harvest rooms or facilities where a single light SKU needs to serve both veg and flower will find the full-cycle spec range covers both without switching fixtures.

The 0–10V dimming range (40%–100%) lets you dial intensity to developmental stage or DLI targets without swapping hardware — relevant for operations managing multiple rooms at different cycle phases on a single controller infrastructure.

Key Features

Diode stack: Samsung 301B/301H paired with OSRAM emitters. This combination covers blue, white, and deep-red wavelengths with the efficiency and longevity characteristics both diode manufacturers are known for in commercial horticulture applications. Rated L90 lifespan exceeds 54,000 hours — meaning the fixture retains at least 90% of its initial output past that threshold under rated conditions.

Dimming is 0–10V via RJ connector, adjustable from 40% to 100% output. Fixtures can be daisy-chained and controlled simultaneously — up to 160 units per controller — which makes room-scale dimming practical without running individual control lines to each fixture. This is the same RJ-based daisy-chain architecture used across Flexstar's broader Pro Series line, so it integrates with compatible Flexstar control infrastructure.

Passive thermal management keeps the fixture silent and removes the maintenance variable of fan motors degrading in humid grow environments. The IP66 rating covers both water spray and dust ingress — appropriate for rooms with overhead irrigation, misting systems, or high-pressure cleaning protocols. Backed by Flexstar's 5-year manufacturer warranty.

How It Fits a Build

The 430W Pro is sized for single-canopy rows in commercial rooms where you'd traditionally run a 600W–1000W HID per light position. At 37% lower power consumption compared to equivalent HID output, the energy load reduction translates directly to lower HVAC demand and reduced electrical infrastructure cost per room — two of the largest capex and opex variables in a commercial build.

Multi-voltage input (120V / 208V / 240V / 277V) means the fixture lands cleanly on whatever electrical standard your facility runs — no step-down transformers, no wiring modifications. Mounting height of 6" or greater above canopy gives you tight spacing flexibility in low-ceiling rooms or multi-tier vertical builds.
