Q3’s collector then pulls q2’s base towards ground, switching it off, which in turn switches off the main pass transistor (q1). Most of the components will be available in ones scrap box. But, high power leds produce much amount of heat. The reverse of the posted circuit does work, at least with 3mm warm white leds and not a 1w.
