Unfortunately, the article provides nowhere near The specified 12Watt! In operation with 2x 3W spot everything is still ok. From 3x3Watt Spot (Ie just 9Watt utilization!) It only flashes. Since I have tried 2, I can also rule out a defect. The 3 LEDs had lt. Manufacturer 3 watts power consumption. Can only confirm the execution of Marcus.
