The LPX4P leverages the best features of ALW’s legacy linear lighting lines while introducing new enhancements in performance and installation efficiency. It is crafted to deliver maximum value, enabling design professionals to bring their vision to life without compromise. From optics and finishes to control systems and mounting options, the LightPlane+ platform ensures every detail of the fixture integrates seamlessly into the architectural environment.
Designed with contractors in mind, the recessed perimeter model simplifies installation with user-friendly details such as snap-in lenses, single-tool installation, and field-adjustable sliding mount points. This streamlined approach not only saves labor time but also reduces the complexity of managing large-scale lighting projects. The comprehensive family allows specifiers to fill an entire linear fixture schedule using one system, simplifying order management and execution.
Technically, the LPX4P features a 4-inch aperture with a 4.25-inch housing height and is offered in both individual and continuous run sections starting at 2 feet. It provides a direct distribution of light with an output range of 350 to 1,500 lumens per foot, reaching efficacies as high as 169 lm/W. The fixture supports a full range of color options, including static white in 2700K, 3000K, 3500K, 4000K, and 5000K; tunable white ranging from 2700K to 6500K; and both RGB and RGB+W dynamic lighting. With CRI options of 80 and 90+, it ensures accurate color rendering for a wide variety of applications.
A broad array of driver and dimming options enhances compatibility with modern control systems, including 0-10V, phase dimming, DALI, DMX, eldoLED, Lutron, and PoE platforms such as Molex, NuLEDs, and WTEC Smartengine. Integrated embedded controls are available with leading systems like Acuity nLight, Casambi, Cooper Wavelinx, Enlighted, Lutron Athena, Lutron Vive, NX Controls, and Wattstopper, ensuring seamless integration into building automation networks.
The LPX4P consumes between 3 and 11 watts per foot and is available with multiple optical distributions including Lambertian, low glare (UGR <16), widespread, and asymmetric. Lens options include standard flush, regressed (3/4”), Reveal, and ControlRoll configurations, providing design flexibility across a variety of environments. The housing is constructed from 100% recyclable extruded architectural-grade 6063 aluminum with a minimum wall thickness of 0.09 inches, combining durability with environmental responsibility.
Performance longevity is another defining feature of this perimeter system. At 80 CRI, the fixture achieves a calculated L70 life of 180,000 hours and L80 life of 119,000 hours. At 90 CRI, it delivers 171,000 hours at L70 and 108,000 hours at L80, ensuring reliable long-term operation.
The fixture is ETL Listed for both U.S. and Canada, suitable for dry or damp locations, and meets UL 1598 and UL 2018 standards depending on the driver configuration. It is also certified to CSA C22.2 and can be specified to comply with California Title 24 JA8 and JA10 requirements. Select driver options from EldoLED and Lutron meet the IEEE P1789 Flicker Standard, supporting healthy lighting environments.
For added resilience, the LPX4P can be specified with a variety of emergency options, including 10W emergency batteries, EMC circuits, generator transfer devices, and automated load control relays. With sixteen standard powder coat finishes and custom color options available, this recessed perimeter system adapts to a wide range of architectural styles. Backed by an industry-leading 11-year warranty, the LPX4P delivers the performance, sustainability, and versatility required by today’s lighting design professionals.
