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