FLEXSTAR 1000W Pro 4*6

What It Is

The Flexstar 1000W Pro 4×6 is an eight-bar LED fixture designed for licensed commercial cannabis and hemp production. It runs on Samsung 301B/301H and OSRAM diodes arranged across a wide-bar array that spreads light uniformly across a 4×6-foot canopy zone. The driver is detachable — mount it remotely to cut radiant heat over the canopy and simplify future service. Bars fold flat up to 180°, which reduces the fixture's shipping profile and makes installation into tight vertical rack bays significantly cleaner than rigid-frame alternatives.

At 1,000W draw, the fixture produces 2,800 µmol/s total PPF at a 2.8 µmol/J efficacy rating. Passive thermal management handles heat dissipation without active fans — no moving parts, no fan noise, no fan failure points. The IP66 waterproof rating means the fixture holds up through routine sanitation cycles and high-humidity rooms without additional protection.

Who It's Built For

The 1000W Pro targets commercial operators running multi-light rooms where consistent canopy-level PPFD and reliable fixture behavior over thousands of hours matter more than entry-level sticker price. The fixture covers a 4×6-foot zone, making it a natural fit for 4-foot-wide rolling bench systems and standard commercial table layouts. Because it handles the full growth cycle — germination through late flower — operators running perpetual harvest schedules can standardize on a single SKU across veg and flower rooms rather than managing two separate fixture types.

Facilities retrofitting from double-ended HPS will find the 0-10V dimming range (40 / 50 / 60 / 80 / 100%) useful for dialing intensity to match crop stage, strain sensitivity, or room-level environmental targets. Wide voltage compatibility — 120V through 277V — means the fixture drops into existing 208V or 277V commercial electrical infrastructure without a transformer.

Key Features

Diode selection is Samsung 301B/301H paired with OSRAM — a combination chosen for output stability and spectral quality across the fixture's rated lifetime. The full-spectrum output is balanced for photosynthetically active growth at every stage, not tuned exclusively for flower. Passive external thermal management keeps the heat path off the grow space; no airflow is required across the driver to maintain operating temperature.

Dimming is handled via 0-10V signal through the RJ connector — compatible with standard environmental controllers used in commercial rooms. Bars fold to 180°, which matters in dense vertical grows and multi-tier rack setups where rigid fixtures create dead space or create clearance problems between tiers. The detachable driver further separates the fixture's electrical heat load from the light-emitting surface, giving operations teams more flexibility in HVAC zone management. Backed by a 5-year manufacturer warranty.

How It Fits a Commercial Build

In a standard 4-foot bench configuration, one 1000W Pro covers a single 4×6 bay. Rooms are typically laid out with fixtures on a 1:1 basis per bench section, allowing straightforward photon-mapping and eliminating the overlap calculations required with circular or asymmetric beam patterns. The 47.6-inch length and 66.45-inch spread align with commercial bench widths without requiring custom hanging hardware.

For operations scaling canopy, the fixture's uniform output across the 4×6 zone and passive cooling profile reduce the HVAC offset load compared to HID equivalents at equivalent wattage. The 0-10V control signal integrates with TrolMaster, Argus, Priva, and most other commercial climate and lighting control platforms without add-on hardware. Whether you're building out a new room, adding a second flower tier to an existing space, or converting an HPS room row by row, the 1000W Pro 4×6 is sized for straightforward bay-by-bay integration into a production build.
