Consultants’ Comments

  • “Love the weight and not having to deal with a cord. Best light I’ve tried yet.”
  • “Needs to weigh less.”
  • “I liked the way the magnet and battery connectors worked for the on off switch. I thought the design was quite ingenious.”
  • “Make the composite filter more secure.”
  • “The battery lasts about four hours, however there is a second light.”
  • “It would be good to be able to tell how much battery life is left without removing the headlight and placing it back on the charging unit.”
  • “I had to remove the mount of my other headlights to accommodate the fixture for the Firefly….but it was worth it. I do not use a light all the time but this is just a wonderful system.”

Clinical Tips

  • Use the fixation screw to help keep the light adjusted in the position you want.
  • Cordless feature gives you more freedom to move your head.

Evaluation Highlights

FireFly was evaluated by 20 consultants, with an average of 68 uses per consultant.

  • Lightweight, cordless, and easy to install and use. A really cool light.
  • Great visual indicator of how charged the pod actually is at a given time.
  • Good light intensity, and easy to mount. A little tough to adjust light intensity on the fly.
  • Excellent visual field. • Portability is good, and recharge of the light/battery pods is quick and easy.
  • Allow more permanent adjustment/fixation of the light position.
  • An on/off mechanism would help, so it could be left on the mounting.
  • Could do with a better amber filter and perhaps a gasket.
  • Visual indicator on the charging station is great.


  • Use for all procedures requiring loupes for visualization of the clinical field.
