BLWP4 LED Wall Pack | Lithonia Lighting
Our BLWP4 LED wall pack combines rugged die-cast aluminum construction with high-efficiency LED technology to deliver reliable perimeter lighting for commercial and industrial applications. Engineered for parking structures, loading docks, building entrances, and outdoor walkways, this fixture delivers 3,000 to 6,500 lumens depending on configuration while maintaining DLC Premium qualification for utility rebate programs.
The Lithonia BLWP4 ships in four wattage configurations — 28W, 37W, 46W, and 55W — each calibrated to deliver the precise footcandle levels required by IES RP-20 outdoor lighting standards. A 37W model producing 4,500 lumens replaces a 150W metal halide fixture while cutting energy consumption by 75 percent.
Housing Construction & Weather Resistance
We manufacture the BLWP4 housing from one-piece die-cast aluminum, eliminating seams that trap moisture and corrode over time. The powder-coat finish meets ASTM B117 salt-spray testing standards — critical for coastal installations where salt fog accelerates metal degradation.
The impact-resistant polycarbonate lens carries an IK08 rating, meaning it survives repeated strikes from a 5-joule steel pendulum without cracking. Gasket seals around the lens perimeter maintain IP65 ingress protection, keeping dust and high-pressure water jets out of the optical chamber. We test every production batch in thermal chambers cycling from -40°F to 122°F to verify seal integrity across the full operating range.
Dimming Controls & Smart Integration
Every BLWP4 includes factory-installed 0–10V dimming leads, allowing integration with wall-mounted dimmers, photocells, and occupancy sensors without field modifications. Dimming to 10 percent output extends LED life beyond the rated 100,000 hours while cutting nighttime energy use during low-traffic periods.
For adaptive lighting strategies, the BLWP4 pairs with dual-technology occupancy sensors that maintain 30 percent output during vacant periods and ramp to 100 percent when motion is detected. The same thermal-management engineering found across our outdoor security lighting catalog ensures the LED junction temperature stays below 85°C even at full output in 100°F ambient conditions, preserving lumen maintenance through the warranty period.

Common Questions About the BLWP4 LED Wall Pack
The BLWP4 ships in four wattages — 28W, 37W, 46W, and 55W — each delivering proportionally higher lumen output. A 28W model produces approximately 3,000 lumens suitable for walkways and building entrances, while the 55W configuration delivers 6,500 lumens for large parking areas and loading docks. All wattages share the same die-cast housing and 5-year warranty. Choose wattage based on your required footcandle levels; most commercial parking applications use the 37W or 46W models.
Yes, every BLWP4 includes a twist-lock photocell receptacle on the top of the housing. Use any standard button-style photocell rated for 1000W inductive loads. We recommend fail-on photocells to ensure the fixture stays lit if the sensor fails. The photocell mounts directly without requiring an external junction box. For facilities needing precise scheduling independent of daylight, consider an astronomic timer instead.
The LED array is rated for 100,000 hours at L70, meaning it will maintain at least 70 percent of its initial lumen output after 100,000 hours of operation. At 12 hours per night, that translates to approximately 22 years. The solid-state LED driver typically lasts the life of the fixture in properly surge-protected installations. Unlike HID lamps that fail suddenly, LEDs gradually dim over decades, so you’ll never experience a complete outage from LED degradation.
Yes, the powder-coated die-cast aluminum housing meets ASTM B117 salt-spray resistance standards required for coastal installations. The IP65 ingress rating prevents saltwater intrusion into the optical chamber. We have BLWP4 installations within 500 feet of ocean shorelines showing no corrosion after three years of exposure. For extreme marine environments with direct salt spray, consider applying an additional clear protective coating to fasteners and mounting hardware.
No, standard wall switches only provide on/off control. The BLWP4 uses 0–10V dimming protocol, which requires a compatible low-voltage dimmer, photocell with dimming output, or occupancy sensor with 0–10V leads. These controls connect to the purple and gray dimming wires inside the fixture. Dimming to 10 percent output is possible; the fixture will not turn completely off via the 0–10V leads. Full power interruption still requires switching the line voltage.
Most commercial parking applications use 4000K, which provides neutral white light that renders colors accurately without the yellow cast of older HID fixtures. The 5000K option delivers cooler blue-white light preferred for industrial settings where maximum visual acuity is required. The 3000K warm white option suits hospitality and retail environments where ambiance matters. All three color temperatures deliver identical lumen output and energy efficiency on the BLWP4.
Yes, every BLWP4 configuration holds DLC Premium certification, qualifying it for Tier 2 utility rebates in most states. Rebate amounts vary by utility provider but typically range from $30 to $60 per fixture. Check your local utility’s commercial lighting rebate program for exact amounts. DLC Premium status also ensures the fixture meets strict efficacy and lumen maintenance standards, guaranteeing long-term performance beyond the rebate period.
