the input current is 90mA light emitting tube current 26mA or more. Magnet detached from the waste energy-saving lamps, diode 1N5819 1N4148 find available alternative. 47uF tantalum capacitors can not find, can also be used instead of electrolytic capacitors 25-47uF, only slightly lower efficiency, even though there are so luminous tube current 20mA. Modified single cell flashlight pays.
