Why Choose the Phantom PHENO 440

The PHENO 440 is built around three core priorities: output efficiency, operational flexibility, and straightforward installation. Here is what distinguishes it from generic LED panels in the same wattage class.

• 2.5 μmol/joule efficiency at 277V. At full power the fixture produces 1,100 μmol/s from 440W of draw, placing it in the upper tier of commercially available 400–500W LED systems for photon-per-watt conversion.
• On-board dimmer with no additional hardware required. The integrated knob steps the output to 40%, 60%, 80%, or 100% of maximum flux without a separate controller. For fully automated control, turning the knob to EXT hands off to any standard 0–10V dimming system.
• Two adjustable light bars. The spread of the fixture can be widened or narrowed by repositioning the two light bars, allowing the grower to tailor coverage without moving the fixture or adding supplemental lighting.
• Multi Phase spectrum across all dimming levels. The red-to-blue ratio of the MP spectrum is fixed — it does not shift when the output is reduced. A plant receiving 60% intensity is receiving the same spectral composition as at 100%, only with proportionally fewer photons.
• DLC listing and utility rebate eligibility. The H-LORIQO2 DLC listing makes the PHENO 440 eligible for rebates from many utility companies. For operations replacing legacy HID fixtures, this can offset a meaningful portion of the purchase cost.
• Wide voltage range. The 100–277V driver accepts both standard 120V North American single-phase circuits and the 208–277V circuits common in commercial and facility environments, with no adapter needed.

Best Uses for the Phantom PHENO 440

The PHENO 440 is suited to a range of controlled-environment applications where a grower needs reliable, full-cycle LED output from a compact form factor.

• Medium-footprint indoor grow rooms (3×3 to 4×4 ft canopies). At 31.49″ × 16.8″, the fixture fits naturally over a single-plant or tight multi-plant canopy in a dedicated grow tent or room. The adjustable light bars allow coverage tuning without repositioning the fixture.
• Full-cycle cultivation (vegetative and flowering). The Multi Phase spectrum is designed to provide an appropriate red-to-blue ratio for both growth stages. A single fixture can run a plant from clone or seedling through harvest without a spectrum swap.
• Operations replacing 400–600W HID systems. The 440W draw and 1,100 μmol/s output position the PHENO 440 as a direct replacement for single-ended 400W or double-ended 600W HPS setups, with lower heat output and no lamp replacement cycle. The included 10-foot 120V cord makes the swap straightforward. For higher-output LED options, see the Gavita Pro 1700e LED, which covers larger footprints at 1,700 μmol/s.
• Staged or multi-zone facilities with 0–10V control systems. Setting the knob to EXT allows the fixture to be integrated into automated lighting controllers that use the industry-standard 0–10V signal, making it compatible with most commercial grow management systems.
• Utility rebate-eligible retrofits. Facilities working through an energy efficiency program can use the DLC H-LORIQO2 listing to substantiate rebate applications when switching from HPS or other legacy sources.
• Propagation and early-stage lighting with reduced intensity. The 40% dimming position (440 μmol/s / 176W) provides a lower-intensity option suitable for seedlings, cuttings, and young vegetative plants that do not yet require full fixture output. For dedicated propagation setups, a heated propagation kit with T5 lighting may complement earlier stages before plants transition to the PHENO 440.

Phantom PHENO 440 vs Similar Products

The PHENO 440 (SKU PHL440LMP) sits in the mid-range LED fixture segment at 440W. A secondary listing of the same unit from a different distributor (mass-hydro, SKU PHL440LMP) is offered at $549.99 — the same hardware at a higher price point, with no specification differences noted.

Within the broader 400–500W LED class, the key differentiators for the PHENO 440 are the on-board dimming knob with EXT position, the adjustable dual light bars, and the DLC listing. Fixtures in the same wattage range that lack on-board dimming require a separate 0–10V controller to modulate output, adding cost and a controller dependency. The adjustable light bars are also not universal in this segment — many fixed-bar designs require repositioning the entire fixture to change spread.

At 2.5 μmol/joule PPE, the PHENO 440 is competitive but not at the top of the efficiency range for modern commercial LEDs. Growers who prioritize peak efficiency above 2.7–3.0 μmol/joule or who need coverage above 5×5 ft should evaluate higher-output fixtures. For single-canopy or moderate-density grows where the $670 price point is a consideration, the PHENO 440 offers a well-specified package without the complexity of external dimmer hardware.

Compatibility

The PHENO 440 is compatible with a wide range of grow room electrical setups because of its 100–277V driver. The following conditions apply.

• 120V single-phase (standard residential/commercial outlet): The included 10-foot 120V power cord connects directly to a standard grounded outlet. No adapter or step-up transformer is required.
• 208–277V circuits (commercial facilities): The driver accepts these voltages natively. A compatible 208–277V cord set will be required in place of the included 120V cord when wiring to higher-voltage circuits.
• 0–10V dimming controllers: Turning the on-board knob to EXT enables full 0–10V external control. The fixture is compatible with any lighting controller that outputs a standard 0–10V analog signal.
• Timer and relay controls: The fixture can be switched on/off via any timer, relay, or lighting controller capable of handling the 440W (approximately 3.7A at 120V) load.
• Grow tents and sealed rooms: At 31.49″ × 16.8″ × 4.1″ and 19.4 lbs net weight, the PHENO 440 is compatible with 4×4 ft and larger grow tents that use ratchet hangers or adjustable rope hangers rated for at least 25 lbs.

The PHENO 440 does not require a separate ballast or driver — it is a fully self-contained LED system. If you are also looking for appropriate extension cord options for your installation, see the Faven Chroma 120V power cords for compatible cord sets.

Usage Guidelines

The following guidelines are derived from the manufacturer’s dimmer output data and standard LED fixture practice for this fixture category.

Coverage area. A 440W LED fixture at this efficiency class typically covers a 3×3 to 4×4 ft canopy during flowering and up to a 4×4 to 5×5 ft area during vegetative growth. The two adjustable light bars allow the grower to widen or narrow the spread to better match the actual canopy footprint.

Mounting height. LED fixtures at 440W are generally positioned 18–36 inches above the canopy depending on growth stage and plant sensitivity. Hang higher (30–36 inches) during early vegetative growth or when plants are light-sensitive, and lower (18–24 inches) during peak flowering when plants can handle higher PPFD. Adjust based on observed plant response rather than a fixed number.

Dimmer knob settings by growth stage.

• Seedlings and early cuttings: 40% (440 μmol/s / 176W). Young plant tissues are sensitive to high PPFD. Start low and increase output gradually as the root system establishes.
• Mid vegetative growth: 60–80% (660–880 μmol/s / 264–352W). As the canopy fills in and root mass increases, step up the output to drive faster vegetative development.
• Flowering and finishing: 80–100% (880–1,100 μmol/s / 352–440W). Full output is appropriate for most flowering strains with adequate CO₂, nutrient, and irrigation support.
• 0–10V automated control (EXT position): Set the knob to EXT and connect a 0–10V lighting controller. The controller then manages ramp-up, ramp-down, and daily light integral (DLI) schedules automatically.

Photoperiod. Vegetative cycles typically run 18 hours on / 6 hours off. Flowering cycles run 12 hours on / 12 hours off for photoperiod-sensitive varieties. Use a timer or lighting controller to maintain consistent schedules.

How to Install the Phantom PHENO 440

1. Prepare the mounting point. Identify the hanging location in your grow space. The fixture measures 31.49″ × 16.8″ and weighs 19.4 lbs. Use ratchet hangers or adjustable rope hangers rated for at least 25 lbs and secure them to a cross-bar, tent frame, or overhead support rated for the load.
2. Hang the fixture. Attach the hangers to the fixture’s hanging points. Set the initial height at approximately 24–30 inches above the expected canopy level. You can lower the fixture once plants are established and you have confirmed they are responding well to the light intensity.
3. Adjust the light bars. The two adjustable light bars can be repositioned to widen or narrow the light spread. Set them to match the width of your canopy before powering on.
4. Connect the power cord. Plug the included 10-foot 120V cord into a grounded outlet on a circuit that can support the 440W draw. If using a 208–277V circuit, substitute a compatible cord set (the included cord is 120V only).
5. Set the dimmer knob. For manual control, set the knob to the desired output level (40%, 60%, 80%, or 100%). For automated 0–10V control, set the knob to EXT and connect the fixture to your lighting controller’s 0–10V output.
6. Connect to timer or controller (if applicable). Wire the outlet or relay to a timer set for the desired photoperiod, or connect through your facility’s lighting control system.
7. Power on and verify. Switch on the circuit. Verify the fixture illuminates and the indicator is active. Check that the light spread covers the intended canopy area. Adjust hanger height if needed based on observed canopy response over the first few days.
