• Allows for comfortable ocular fundus observation through the use of halogen-like colored LED-bulb illumination.
  • Clear lighting that does not have a filament shadow, unlike normal light bulbs.
  • The service life of the LED is at least 50,000h,*1 eliminating the hassle of replacing light bulbs.
  • The rechargeable battery pack includes safe NiMH batteries.
  • The energy-saving effect of using LED allows for 10h of continuous illumination.*2
