Frustrated with being locked into a single beam pattern that doesn't suit different lighting scenarios? Stock flashlight optics force you to compromise between flood coverage and throw distance, limiting your torch's versatility for close-up work, area illumination, and long-range applications.
This professional quad TIR lens set transforms your S21D or S21F flashlight into a versatile lighting tool with four distinct beam patterns. Total Internal Reflection technology delivers superior light efficiency compared to traditional reflectors, ensuring maximum output whilst providing precise beam control for every situation.
The comprehensive collection includes 60-degree flood optics for wide area coverage during camping or mechanical work, 30-degree medium beam for balanced general use, and dual 10-degree options (beaded and flat) for focused throw applications. Each lens optimises light distribution differently, allowing you to customise your flashlight's performance to match specific tasks.
Perfect for flashlight enthusiasts and professionals who demand optimal beam characteristics, these precision-engineered TIR lenses upgrade your existing torch without requiring new equipment. Simply swap lenses to instantly adapt your lighting for photography, tactical use, outdoor exploration, or detailed inspection work.
