Valid schematic circuit diagrams of fluorescent lamps with a voltage source using 12 volt battery. This circuit 12 volt fluorescent lamp is very useful if the power goes out or can be used in a dark place with no electricity , but can use the battery 12V . This 12V fluorescent lamp circuit i have tried and the results are bright , durable until decades. You can use 12Volt fluorescent lamps up to 40W . Use quality 12 Volt fluorescent lamp, do not use the fast heat , because the fast was also damage the transistor at 12Volt fluorescent lamp circuit . Do not occasionally mistaken in putting up the transistor . Description for 12 volt fluorescent lamp Circuit Diagrams : R1 = 220R/0.5W R2 = 1/0.5W C1 = 100n/100V C2 = 220uF/50V Q1 = D1885/D1710 A/B= To A fluorescent lamp/ and B to B fluorescent Lamp and just use one pin B = Battery 12 volt with currents above 5A Roll of copper wire on ferrite rod, with : L1 = 1.2 mm diameter wire with many loops winding 20 times L2 = 1.2mm di...
