The chart shows the high frequency producing lamplighter circuit. It uses the 8V ~ 14V battery as energy source, and boosted by oscillation and then lights 6W ~ 12W fluorescent lamp. The transistor VT can use 3DD12A, D3D4D, 3DD5C, 3DDl5A and other low-frequency high-power transistor, it should be installed the 70mm × 40mm × 2mm of aluminum radiator when assembling; potentiometer RP should use a small wire wound type; frequency pulse transformer T can be self-made by ferrite magnetic tank with diameter in 22mm; coil L1 uses a high-strength magnet wire with 9 turns and diameter in lmm and rolled flatly on framework; feedback coil L2 uses a high-strength magnet wire with 8 turns and diameter in 0.3mm and rolled flatly on L1; coil L3 uses a 0.2mm enameled high-strength magnet wire with 900 turns and diameter in 0.2mm.
