90mm 42pcs Bottom LED Light Source Stereo Microscope AM-42-90

The 90mm 42pcs Bottom LED Light Source Stereo Microscope AM-42-90 is a compact, bottom-mounted LED illumination unit designed for use with stereo microscopes. It provides uniform, adjustable white light (6400K) across a 69mm diameter area with 42 individual LED patch light-emitting tubes. The unit operates on AC 90–265V, 50/60Hz input and delivers DC24V, 3.6W output. It features linear dimming from 0% to 100% and a long LED lifespan exceeding 100,000 hours.

  • Bottom-mounted LED ring light with 69mm illumination diameter for consistent sample lighting
  • 42 high-efficiency LED patch tubes ensure even brightness without hotspots
  • Linear dimming from 0% to 100% allows precise control for sensitive or reflective samples
  • Wide input voltage range (AC 90–265V) supports global power standards
  • Long LED life (>100,000 hours) reduces replacement frequency and maintenance
  • Compact 90mm diameter design fits standard microscope mounting interfaces
