On occasion purchased a portable led flashlight in China with the battery inside. The flashlight has the ability to switch between a cluster of eight super-bright LEDs and a krypton bulb for a voltage of 5.4 V. Inside there is also a charger for the battery. In addition, the lamp is combined with a lamp – a fluorescent light with a power of 6W, powered by using a special voltage Converter 150 – 6th Century
Lighting using energy saving lamps (hereinafter – EL) of the type Osram Dulux S7W implemented in this design, very convenient for many purposes. With it you can read in the tent, in camping, in marching conditions continuously for six hours due to low power consumption lamp with fully charged built-in battery. Testing flashlight lamp with energy-saving lamp “strength” has been conducted in rural areas throughout the year. Schematic of the voltage Converter seems to me a very successful and valuable for replication in other structures, and for use ready Converter Board to power up ELECTRIC power up to 8 watt aquarium light. Electric circuit device of the Converter, copied from the printed circuit Board and is shown in Fig.
