Light Fitting Perforated Sheet
Designed for high-spec commercial and industrial lighting fixtures, our Light Fitting Perforated Sheets are engineered to maximize both light diffusion and heat dissipation. Crafted using CNC micro-punching tolerances (±0.05mm), the micro-perforations prevent glare while optimizing airflow to cool critical LED drivers. Finished in ultra-high reflective powder coatings for maximum lumen output.
Key Features
CNC micro-punching tolerances (±0.05mm) for seamless lighting optics
Optimized open area for maximum heat dissipation and long component life
Premium electrostatic powder coatings with high-reflectivity indexes
Compliant with international architectural lighting standards
Common Applications
High-performance commercial LED luminaires and troffersIndustrial high-bay lighting shields and cleanroom light boxesArchitectural pendant diffusers and retail spotlight bafflesOutdoor street lighting heat sinks and protective grilles
