Performance & Light Output

The LHS1-PS440 VDIM delivers the highest lumen output in the LHS1 series, identical to the HDIM model across all wattage steps: At 440W: 66,000 lm (4000K & 5000K / 150 lm/W). At 380W: 57,000 lm (4000K & 5000K / 150 lm/W). At 320W: 48,000 lm (4000K & 5000K / 150 lm/W). At 280W: 42,000 lm (4000K & 5000K / 150 lm/W). CRI ≥80 across all settings. Rated life 100,000 hours L70 per IES TM-21.

Smart & Control Features

The LHS1-PS440 VDIM is Controls Ready — a 1/2" knockout port on the fixture front plate accepts field-installable screw-in sensors without additional wiring.

• Standard Dimming: 0-10V analog dimming
• Standalone PIR Sensor: SEN5A-SPPR-WH — screw-in PIR motion sensor; up to 40 ft mounting height
• Standalone Microwave Sensor: SEN5A-SPMR-WH — screw-in microwave sensor; recommended for high-ceiling or obstructed-line-of-sight applications where PIR coverage may be limited
• Bluetooth Networked Sensor: SEN5A-WPPA-WH — BLE screw-in PIR; enables zone/group control, daylight harvesting, scheduling, and energy monitoring via Silvair App (no hub required)
• Wireless Wall Controllers: PSC-DM-WS-100-BLE-SR (single gang), PSC-DM-1-WS-100-BLE-SR (PIR + vacancy), PSC-DM-WS-400-BLE-SR (4-button) — Silvair App configured; verify voltage compatibility with 480V system wiring
• Commissioning Tool: SEN5A-ACT for standalone sensor configuration
• Emergency Battery: Specify factory-installed EB suffix at time of order — confirm 480V-compatible battery model with EIKO before ordering

Electrical

The LHS1-PS440 VDIM operates on 277–480V input, 50/60Hz, Class P driver with 6kV integrated surge protection. Power factor >0.9 and THD <20%. Input watts vary by wattage setting: 280W, 320W, 380W, or 440W nominal. This is the correct SKU for facilities with 480V three-phase or 277V branch circuit systems. For 120–347V systems, specify LHS1-PS440-8FCCT-HDIM instead. Green technology: mercury-free, UV-free LED source, RoHS compliant.

Construction

Heavy-gauge steel housing with white powder-coat finish. Diffused polycarbonate lens. Fixture weight: 22.4 lbs. Operating temperature range: -40°F to +122°F (-40°C to +50°C). UL Listed for damp locations.

Installation & Mounting

Typical Applications

• 480V Industrial Facilities — Factories & Heavy Manufacturing: Purpose-built for facilities with 480V three-phase electrical systems — eliminates the need for step-down transformers required by standard 120–347V fixtures at maximum output
• Very High-Ceiling Warehouses & Distribution Centers: 380–440W setting delivers 57,000–66,000 lm for 30–50 ft ceiling heights in large-span fulfillment centers on 480V industrial power
• 277V Commercial & Institutional Buildings: Ideal for large commercial buildings, universities, and municipal facilities wired on 277V branch circuits from 480V panels with very high mounting heights
• Aircraft Hangars & Vehicle Maintenance Bays: 50 ft effective ceiling coverage at 440W on 480V power makes this the correct specification for extra-tall industrial maintenance facilities
• Cold Storage & Refrigerated Distribution: -40°F cold-start rating supports freezer warehouse and refrigerated facility applications at full 66,000 lm output with no warm-up delay
• Municipal & Public Works Facilities: DLC Premium certification maximizes utility rebate eligibility to reduce project cost on government-funded 480V high-bay retrofits
