With the proliferation of LED bulbs are progressively disappearing the neon and the classic incandescent lamps, essential, due to the 50 Hz of operation, for the use of the stroboscopic disk for speed regulation. In any case, even if you have an "old" traditional lighting source, the 50Hz of the network can have slight oscillations. The safest and most effective way to proceed is to create an oscillator with an absolutely perfect frequency of 50 periods and use an LED as lighting. This accessory allows precise and unambiguous verification of the correct rotation of the disc at 33, 45 and 78 rpm.
Composed of two parts, the classic thick metal stroboscopic disc coupled in the underlying part with a non-slip pom layer and the unit generating the constant 50Hz pulse. Very well done and shipped in a wooden box.
