The Paradox in-grade marker light establishes a benchmark for sealed in-grade technology, serving applications where minimal aperture size, shallow luminaire depth, or site conditions necessitating sealed construction are critical. Its compact 4-inch form factor integrates a static LED light source available in 3000 K, 4100 K, 5300 K, Amber Phosphor Corrected, Blue, Green, and Red, with CRI options of 70 or 80. The fixture’s 9-watt monochromatic LED operates within 3-MacAdam ellipses to maintain consistent color performance, while its optical distributions are selected through the ordering guide to match pathway, marker, or architectural accent needs. The fixture supports mechanical aiming, enabling precise adjustment even within a sealed housing, and its Cool Lens Technology helps manage temperature at the lens surface to improve performance and longevity.
Lighting control compatibility includes 0-10V dimming, allowing the in-grade luminaire to integrate with standard architectural lighting control systems for intensity management across diverse environments. Its electrical flexibility includes a wide range of voltage ratings—120, 120-277, 230, 240, 277, and low-voltage configurations—making it adaptable to both line-voltage and remote-transformer installations. The fixture achieves an IP68 rating and carries UL Wet Location listing, ensuring durability in environments exposed to rain, irrigation, or ground moisture. Government procurement qualifications under the Buy American Act and Build America, Buy America further support specification in federal and transportation projects.
The Paradox construction centers on durability and long-term reliability, beginning with a die-cast bronze door and a housing composed of die-cast bronze and injection-molded thermoplastic. The housing is UV-stabilized, corrosion resistant, and impact resistant for use in varied environmental conditions. The patent-pending door and lens seal employs proprietary knife-edge technology that secures the borosilicate glass assembly to the housing using two captive screws, while a notched lens design maximizes aperture opening. Multiple conduit entry points—two standard ½-inch NPT side entries with optional bottom entries—support a variety of wiring approaches during installation. A modular approach streamlines both installation and maintenance, and the system integrates with a remote-mounted, NEMA-rated transformer (sold separately), with transformer and enclosure options available through Hydrel’s standard accessories catalog.
Designed for direct burial and in-grade mounting, the Paradox marker light provides a sealed, shallow-depth solution for wayfinding, landscape accents, plazas, architectural perimeters, and hardscape environments requiring robust, low-profile lighting. Its natural brushed bronze finish reinforces durability and aesthetic longevity, completing a system ready for demanding in-ground applications where reliability, optical consistency, and sealed performance are essential.
