Kill Variance. Print Yield.

Legacy HPS infrastructure does not fail loudly — it fails on a schedule you cannot see. Every hour a 1000W DE HPS operates past its rated depreciation curve, the photon output delivered to your canopy is lower than the output your nutrient program, your VPD targets, and your yield projections were built around. Lamp replacement cycles introduce re-calibration windows. Manual dimming controls create dead zones between operator interventions. Passive failure points — ballast drift, reflector degradation, thermal variance across the fixture — compound silently across every room in your facility, and the cost shows up in harvest weight, not in an alarm on your dashboard.

After deployment of the IONBOARD S44, the facility operates on a different model. Photon output is stable across the rated 50,000-hour lifespan with no depreciation curve to manage. Scheduling, dimming, and multi-fixture coordination are handled through the AC Infinity UIS ecosystem and the AC Infinity app over WiFi — no manual intervention required between programmed events. The canopy receives uniform PAR coverage across the full 4 x 4 ft. footprint because diode positioning is algorithmic, not arbitrary. Lamp replacement cycles are removed from the maintenance calendar entirely. The facility runs on data, not on operator memory.

The mechanism behind that outcome is a 1,024-diode array of Samsung LM301H Horticulture Series LEDs mounted on a fanless unibody aluminum board, driven by the AC Infinity proprietary driver (IB-400 / GTS-100) at 400W across a 100–277V AC input range. The full spectrum architecture spans 660nm deep red, 730nm far-red, 3000K warm white, and 6500K cool white channels — algorithmically positioned to produce the most uniform PAR map and deepest canopy penetration achievable at this wattage class. Dimming is programmable in 20% increments (five levels: 20/40/60/80/100%) and integrates with UIS-compatible controllers for automated deployment across multi-fixture rooms. The fixture draws 3.60A at 120V, 1.80A at 240V, or 1.56A at 277V, and the entire assembly is sealed to IP65 against moisture and particulate ingress. In practical terms, the IONBOARD S44 delivers 1,937 µmol/s at 2.75 µmol/J efficacy across a 4 x 4 ft. production footprint at 400W draw.

Where This Belongs (and Doesn't)

This fixture requires a dedicated circuit sized for the operating voltage selected. At 120V, plan for a minimum 15A dedicated circuit (3.60A draw). At 240V, a 15A circuit accommodates the 1.80A draw. At 277V, the 1.56A draw is compatible with commercial 277V branch circuits. Verify HVAC capacity to offset the fixture's thermal load before deployment in sealed rooms.

Infrastructure Note: The IONBOARD S44 is a fanless passive-cooling fixture. Facility HVAC must be sized to manage the thermal output of the full fixture array independently. The driver unit (10.74 x 1.75 in.) mounts separately from the board (23.62 x 23.62 x 0.5 in.) — confirm mounting clearance and cable routing before installation. Expansion dongle accessories for multi-fixture UIS pairing are sold separately.

How It Works

The IONBOARD S44 operates on a passive thermal architecture: a unibody aluminum board measuring 23.62 x 23.62 x 0.5 in. (60.0 x 60.0 x 1.27 cm) serves simultaneously as the structural substrate, heat sink, and diode mounting surface. With no moving parts and no fans, there are zero mechanical failure points in the light engine itself. Heat generated by the 1,024 Samsung LM301H diodes conducts directly into the aluminum mass and dissipates across the board surface — a design that extends diode operational life toward the rated 50,000-hour threshold without active cooling overhead.

The spectral architecture is a four-channel full spectrum configuration: 660nm deep red for photosynthetic peak absorption, 730nm far-red for phytochrome photoequilibrium and stem elongation control, 3000K warm white for broad-band vegetative and flowering support, and 6500K cool white for blue-spectrum vegetative development and compact internodal spacing. These four channels are not distributed uniformly — diode positioning across the 23.62 x 23.62 in. board is algorithmically calculated to produce the most uniform PAR map achievable at this fixture size, minimizing hotspot variance and maximizing canopy penetration depth across the full 4 x 4 ft. footprint.

Control is delivered through the AC Infinity proprietary driver (IB-400 / GTS-100), which accepts 100–277V AC at 50/60 Hz and provides five-level dimming at 20% increments (20/40/60/80/100%). The driver connects to UIS-compatible AC Infinity controllers, enabling the fixture to participate in automated scheduling, multi-fixture coordination, and ecosystem-level environmental programming through the AC Infinity app over WiFi. Expansion dongles (sold separately) allow additional IONBOARD fixtures to be chained to a single controller node. The entire assembly — board, driver, and all electrical interfaces — is sealed to IP65 standards, rated for continuous operation in environments up to 85% RH and 140°F. In practical terms, the IONBOARD S44 delivers 1,937 µmol/s total photon flux at 2.75 µmol/J efficacy from a 23.62 x 23.62 in. board drawing 400W at 1.80A on a 240V circuit.

System Integration

To operate this platform at peak efficiency, verify your ecosystem matches these requirements:

• Controller Compatibility: UIS-compatible AC Infinity controller required for automated scheduling, dimming automation, and multi-fixture coordination. Controller sold separately. Expansion dongles (sold separately) required for chaining multiple IONBOARD fixtures to a single controller.
• Mounting: Metal bar hangers and rope hangers included. Verify structural overhead load capacity for 12.34 lbs per fixture before installation. Driver unit (10.74 x 1.75 in.) mounts separately — confirm cable routing and clearance.
• Power: Universal input 100–277V AC, 50/60 Hz. Draw: 3.60A @ 120V / 1.80A @ 240V / 1.56A @ 277V. Dedicated circuit required at each voltage tier. Power cord: 5 ft., US Plug NEMA 1-15 Type-A.
• HVAC Capacity: Fanless passive-cooling design transfers all thermal load to the room environment. Size facility HVAC to offset the full thermal output of the fixture array — do not rely on fixture-level active cooling.
• Network: WiFi connectivity required for AC Infinity app integration and UIS ecosystem automation. Verify facility WiFi coverage at canopy level before deployment.

Facility Integration Data

The following ROI model and competitive comparison are provided to support capital planning and procurement decisions for multi-fixture deployments of the IONBOARD S44.

Operator Field Note

• Structural Load: The IONBOARD S44 weighs 12.34 lbs. Verify overhead mounting point load capacity before installation, particularly in multi-fixture grid configurations where cumulative load is significant.
• Electrical — Amps: Draw is 3.60A @ 120V, 1.80A @ 240V, 1.56A @ 277V. Size dedicated circuits accordingly and do not share branch circuits with high-draw HVAC or dehumidification equipment.
• Driver Mounting: The external driver unit (10.74 x 1.75 in. / 22.5 x 4.5 cm) is separate from the board (23.62 x 23.62 x 0.5 in.). Plan driver placement and cable routing before finalizing fixture positions — driver must remain within the 5 ft. power cord reach of the outlet.
• Thermal Management: No active cooling is present in this fixture. All thermal dissipation is passive through the aluminum board. Facility HVAC must be independently sized to manage the aggregate thermal load of the full fixture array — do not assume fixture-level cooling offsets room heat gain.
• Environmental Limits: Rated for 32–140°F operating temperature and 35–85% RH. Operating outside these parameters voids the manufacturer warranty and may accelerate diode degradation.
• UIS Expansion: Multi-fixture automation requires UIS-compatible controllers and expansion dongles, both sold separately. Confirm controller channel capacity against planned fixture count before procurement.
