RUB Is Surface Mounted Track light, made of die-cast aluminum ensures a strong, long-lasting body that resists wear, corrosion, and high temperatures. Aluminum also serves as an efficient heat sink, helping to dissipate heat from the light source, extending the lifespan of the LED. The PMMA lens provides good light transmission, meaning the light output will be bright and clear with minimal distortion, and resistant to UV rays, ensuring long-lasting performance without yellowing or degradation over time.
