2x LED lights By placing the active heat sink in the retrofit body, it is possible to install 1: 1 like a standard halogen bulb without the need for adapters for unusual bulb sockets. It is the only model with a 1: 1 design with an active heatsink, which allows for much more power and luminance than models without an active heatsink. The most important parameter of LED bulbs is the focus of light, which is also the most difficult to achieve. The optimal geometry and arrangement of the diodes allows you to set the required cut-off line and angle of incidence of light and the maximum lighting effect of LED bulbs. Since the tungsten filaments used in standard halogen bulbs light up at the exact center of the bulb, they provide the perfect light pattern and required cut-off in dedicated headlamps by reflecting at the exact center of the lamp's reflector.
