UL 1598 Temperature Rise Test Wall Apparatus for Wall Surface Luminaires

The LS-B74 UL 1598 Temperature Rise Test Wall Apparatus for Wall Surface Luminaires implements a standardized structural configuration specifically engineered for evaluating wall-mounted lighting products. This apparatus is designed to verify temperature rise performance of luminaires in compliance with UL 1598 safety requirements.

This test wall incorporates UL-certified junction boxes, compliant wiring systems, and structural support components to accurately replicate the operational environment of wall-mounted lighting installations. The apparatus features movable brackets and integrated casters, enabling flexible positioning and facilitating laboratory testing workflows and equipment management.

Standardized construction materials including specified plywood dimensions, timber components, and wiring configurations ensure consistent and stable testing conditions. This provides a reliable testing platform for obtaining accurate temperature rise data during simulated operational scenarios.

Standards Compliance: UL 1598:2024 Standard for Safety for Luminaires
