Nakamura LED Strobe Unit

This strobe unit is indispensable for observing the motion of dynamic carriages, vibration cords, and propagation of water waves. This economical solution is designed for portability and the high brightness range is achieved using a high-output LED. The flash rate can be read using a digital tester measuring the frequency range (not provided).
