X-Cite 120LED



  • 500 µsec USB and 50 µsec TTL


  • Fine grain manual or PC control (1%)


  • Mounting flanges to fit all modern microscope models


  • Better than 0.5% over 24 h


  • 25,000 hour warranty 


 X-Cite 120LED offers a much longer lamp life time and less maintenance compared to conventional lamps . Researchers will focus on their experiments instead of equipment service:

  • No bulbs to replace
  • No delicate optical fiber
  • Stable output

The dangers of phototoxicity in fluorescence microscopy experiments are too often ignored.
