PHOTOBIO CX 2125 LED, 850W, 100-277V S4, (10' 120V Cord)

Compact 1000W DE Replacement Toplight, 120V Cord

Growers stepping down from 1000W double-ended HID fixtures want the light output and canopy coverage they're used to without rebuilding their reflector layout. The PHOTOBIO CX 2125 is a compact, high-performance full-spectrum LED fixture built as a 1:1 footprint replacement for a 1000W DE fixture, so it drops into that existing layout.

This configuration ships with a 10-foot 120V power cord, ready to plug into a standard residential or light-commercial receptacle.

Key Features & Benefits

• Auto-Adjusting 100-277V Input — the driver senses and adapts to facility voltage from 100V to 277V automatically.
• 2125 µmol/s Photon Flux at 277V — 2087 µmol/s PPF at 2.5 µmol/J efficacy, sized as a 1:1 footprint replacement for a 1000W DE fixture.
• Secondary Optics — improve canopy penetration and light distribution compared with an open 1000W DE fixture.
• S4 Full-Spectrum LED — Osram/Seoul diodes add red, far-red, and blue wavelengths to support vigorous growth.
• iLOC Integrated Light Output Control — a digital push-button interface adjusts photon output by crop stage and pairs with an Autopilot PX2 or higher controller.

Who Should Use the PHOTOBIO CX 2125

This fixture fits growers replacing 1000W double-ended HID fixtures who want a slim, dimmable LED toplight on standard 100-277V power. The passive cooling fins and 1:1 footprint mean it drops into an existing 1000W DE reflector layout without redesigning the room.

About PHOTOBIO

PHOTOBIO's CX line is built as a direct-footprint LED alternative to double-ended HID fixtures, pairing secondary optics with onboard iLOC dimming so growers can step down from HID without redesigning their canopy layout. This CX 2125 fixture is backed by a 5-year warranty from the Hydrofarm team.

Frequently Asked Questions

Is this a direct replacement for a 1000W DE fixture?

Yes, the CX 2125 shares a similar footprint with a 1000W double-ended HID fixture while delivering higher photon flux and improved canopy distribution through its secondary optics. Most growers can swap it into an existing reflector layout without rebuilding the room.

Can I dim this fixture?

Yes, through the onboard iLOC push-button interface, or by pairing the fixture with an Autopilot PX2 or higher controller for centralized control. iLOC lets growers step output up or down by crop stage without adding an external controller.

How is this fixture cooled?

Passive cooling fins dissipate heat without fans, which keeps operating temperatures low and avoids the added maintenance and noise of fan-based cooling. This works alongside the fixture's slim vertical profile to maximize usable canopy space.

What voltage range does this fixture support?

An auto-adjusting driver accepts 100-277V input, so the same fixture works on standard 120V circuits as well as 208-277V commercial service. No manual voltage selection is required.

What is the warranty?

The CX 2125 carries a 5-year warranty backed by the Hydrofarm team. Register the fixture or retain your invoice so warranty service goes smoothly if it's ever needed.

Is professional installation required?

We recommend consulting a licensed electrician to confirm circuit sizing, receptacle selection, and code compliance before installation, particularly for hardwired or high-voltage configurations. This is standard practice for any commercial-grade lighting install.
