Product Name: Adjustable Microscope Light Source Model: RL-033E Pro For Soldering and Repair Stereo Microscopes A convenient knob allows for smooth, stepless dimming, easily adapting to different viewing objects (such as reflective metal and transparent materials) and ambient lighting requirements, minimizing eye fatigue. Densely arranged, 32 professional-grade LEDs provide powerful and uniform light output, covering a area and reducing shadows. Eliminates bulky traditional light sources that block vision, hinder tool operation, and hinder repair technicians' mobility. Professional optical lens design ensures highly focused light, and the efficient heat dissipation structure ensures long-lasting and stable heat dissipation. Adjustable Brightness A convenient knob allows for smooth, stepless dimming, easily adapting to different viewing objects (such as reflective metal and transparent materials) and ambient lighting requirements, minimizing eye fatigue. 32 High- LEDs Densely arranged, 32 professional-grade LEDs provide powerful and uniform light output, covering a area and reducing shadows. Compact lamp head frees up space. Eliminates bulky traditional light sources that block vision, hinder tool operation, and hinder repair technicians' mobility. High-brightness, concentrated light, and rapid heat dissipation. Professional optical lens design ensures highly focused light, and the efficient heat dissipation structure ensures long-lasting and stable heat dissipation.
