LED board green

LED with a wavelength of 521 nm as a monochromatic light source. Particularly suitable for student experiments in the field of optics. Suitable for the holder for apertures and slides 45933 in 50 mm x 50 mm format with mini USB connection for power supply. The USB connection allows operation using a simple USB plug-in power supply 459095 and USB cable 459096. The non-interchangeable connection with fixed supply voltage via USB protects the LED against polarity reversal and overvoltage. Alternatively, the USB connection of the student power supply 521488 or the USB power bank 459099 can also be used for the power supply.
