Precision Red. Dialed Flowering. Zero Guesswork.

Every day a flowering canopy runs under the wrong spectral balance is a day of yield potential that cannot be recovered. Broad-spectrum fixtures spread photon energy across wavelengths that do nothing for anthesis and fruit set — and when those fixtures are unrated for moisture, a single humid season accelerates electrical degradation before the first replacement cycle is even budgeted. Supplemental lighting that lacks dimming granularity forces operators into binary choices: full power or off, with no ability to modulate intensity as canopy density changes or as natural light levels shift through the season. The result is inconsistent flowering uniformity, variable brix, and a production calendar that never quite locks in.

After deployment, the picture changes. Red-band energy is delivered precisely where the photosynthetic machinery demands it — at the wavelengths that drive phytochrome far-red signaling and chlorophyll absorption peaks. Canopy response becomes predictable. Flowering windows tighten. Operators running mixed-light configurations gain a controllable supplemental layer that integrates with existing HID or broad-spectrum LED infrastructure without spectral conflict. Daisy-chained arrays across an entire greenhouse bay can be dimmed from a single control point, eliminating the per-fixture adjustment labor that erodes margin on every production cycle.

The mechanism behind that outcome is a BridgeLux diode array operating across a precisely bounded spectral window — 650-665nm primary red, supported by 2800-3000K and 4800-5000K channels — delivering 727.2 µmol/s of total photon flux at a system efficacy of 3.3 µmol/J from a 300W ± 5% draw at AC100-277V. The passive thermal architecture — an aluminum shade and robust heat sink with no moving parts — eliminates fan failure as a maintenance variable and keeps the fixture profile at 42.79" × 3.97" × 3.97", thin enough to minimize inter-canopy shading in dense production layouts. IP65 ingress protection qualifies the fixture for high-humidity greenhouse environments without enclosure modification. Dimming is available via RJ12-connected controller, and up to 50 units can be daisy-chained into a single addressable network. In practical terms, the SP 3000R delivers 727.2 µmol/s of targeted red-spectrum photon flux across a 2'x4' coverage footprint at 300W on any supply voltage between 100V and 277V.

Where This Belongs (and Doesn't)

Electrical integration, circuit loading calculations, and HVAC thermal budgeting should be performed by a licensed electrician and mechanical engineer prior to deployment. Cannafull Spectrum Solutions provides specification data to support that process; we do not provide installation engineering services.

How It Works

The SP 3000R is built around a BridgeLux diode array configured to deliver energy across three spectral channels: a primary 650-665nm red band targeting chlorophyll-a and chlorophyll-b absorption peaks and phytochrome photostationary state modulation, supplemented by 2800-3000K warm white and 4800-5000K neutral white channels that provide secondary photosynthetically active radiation to support canopy-level light distribution. This multi-channel architecture within a red-dominant fixture allows the SP 3000R to function as a precision flowering accelerant without creating the spectral void that pure monochromatic red sources introduce at the canopy floor.

The bar-style form factor — 42.79 inches in length at 3.97 inches wide and 3.97 inches tall — is engineered to minimize the shadow footprint in overhead mounting configurations. Slim-profile bar fixtures distribute photon output longitudinally across the canopy rather than concentrating it in a central hotspot, which is the primary failure mode of panel-style supplemental fixtures in greenhouse rows. Passive thermal management via an aluminum shade and integrated heat sink eliminates fan assemblies entirely, removing the single most common mechanical failure point in LED grow fixtures and reducing acoustic output to zero.

Input voltage acceptance spans AC100-277V, drawing 2.499A at AC120V, 1.241A at AC240V, and 1.094A at AC277V — making the fixture compatible with North American 120V single-phase, 240V split-phase, and 277V commercial lighting circuits without a step-down transformer. Dimming is controlled via RJ12 interface; if the unit ships with an external dimming box, the controller connects via RJ12 to enable the dimming feature. Up to 50 fixtures can be daisy-chained into a single control network, allowing a 50-unit greenhouse array to be managed from one controller input. IP65 ingress protection seals the fixture against dust and directed water spray, qualifying it for open greenhouse environments without additional enclosure. Rated lifespan is 50,000 hours. In practical terms, the SP 3000R delivers 727.2 µmol/s PPF at 3.3 µmol/J system efficacy from a 300W ± 5% draw, across a 2'x4' coverage footprint, on any supply voltage between 100V and 277V.

System Integration

• Mixed-Light Compatibility: The SP 3000R is designed to operate alongside existing HID or broad-spectrum LED fixtures; red-band supplementation integrates without spectral conflict in mixed-light configurations.
• Daisy-Chain Scaling: Up to 50 units can be daisy-chained into a single control network via RJ12 interface, enabling centralized dimming management across large greenhouse bays without per-fixture wiring runs.
• Dimming Control: Dimmable via external controller; if the unit includes an external dimming box, connect the controller via RJ12 to enable the dimming feature. Note: some controller items do not include dimming functionality — verify controller specification at time of order.
• Circuit Planning: At AC120V the fixture draws 2.499A; at AC240V, 1.241A; at AC277V, 1.094A. Size branch circuits and calculate fleet amperage loads accordingly before deployment.
• Mounting Geometry: Bar-style form factor (42.79" × 3.97" × 3.97") is optimized for overhead longitudinal mounting in greenhouse rows to maximize canopy distribution and minimize inter-row shading.

Operator Field Notes

• Controller Verification at Order: Not all controller accessories include dimming functionality. Confirm that the controller SKU you are ordering includes dimming capability before assuming full RJ12 dimming control is available out of the box.
• Daisy-Chain Wiring Load: When chaining 50 units at AC120V, the aggregate draw reaches approximately 124.95A. Plan dedicated branch circuits with appropriate breaker sizing — do not share supplemental lighting circuits with other facility loads.
• Passive Cooling Clearance: The aluminum heat sink requires unobstructed airflow along the fixture body. Do not mount in enclosed channels or against solid surfaces that block convective heat dissipation.
• IP65 in Practice: IP65 protects against dust ingress and directed water spray. It does not qualify the fixture for submersion or continuous water contact. Overhead irrigation systems that produce direct spray onto fixtures should be evaluated against this rating.
• Supplemental vs. Sole-Source: The SP 3000R is a supplemental and top-lighting fixture. In greenhouse mixed-light configurations, it augments existing broad-spectrum or natural light input — it is not engineered as a sole-source lighting solution for fully enclosed dark rooms without additional broad-spectrum primary fixtures.
• Spectral Channel Note: The 2800-3000K and 4800-5000K white channels are present in the diode array alongside the primary 650-665nm red. These channels contribute to canopy-level PAR distribution and should be accounted for in spectral planning for mixed-light environments.
