The circuit was designed to experiment with using small fluorescent lamps as a broad pattern source of modulated light. The circuit hits the small lamp with narrow 1us pulses at a rate of 10KHz. Each pulse launches about 10 watts of visible light. The lamp starting method is a bit crude but the circuit does work.

Cold Cathode Fluorescent Lamp Power Supply Circuit
The circuit is an efficiency of 92% for cold cathode fluorescent lamp power supply, backlit LCD display for mobile devices. The circuit efficiency is largely determined by the component types, especially types of C1, Q1, Q2, L1 and T1, the manufacturers of these components have a comment.
