The lamp is electrically projecting, since there is nothing to complain about. However, one must be careful when installing. I'm using for recessed spotlights in principle the "large" void doses of Emperor -is safer especially when fully insulated ceilings. The problem with the antenna elements are in this case, the relatively simple and weak designed Federbuegel, as these can not be completely folded down. And if you work when installing upwards of 50% of the spring force is already gone.
