A light device 10 includes a housing 12 and a tip structure 14 configured to be removably coupled with the housing 12. The tip structure 14 includes a light-emitting device 40 that is operable for emitting light positioned at a distal end 24 of the tip structure 14 and a body 36 for housing the light-emitting device 40. The tip structure 14 is formed of an autoclavable material capable of withstanding autoclaving, A power supply circuit 28 is positioned in the housing 12 and coupled to the light-emitting device 40 to power the device when the tip structure 14 is coupled with the housing 12. The power supply circuit 28 is rechargeable and includes at least one ultracapacitor element 90 for being charged and the power supply circuit 28 configured to discharge the ultracapacitor 90 as a current source to drive the at least one light-emitting device 40. |
