Features:, Not the opinions of the editors of the fragrantica portal. Perfect for railway layout and building! Made of white LEDs. Complete with wires and leds and can be illuminated. These lanterns are only suitable for use at a supply voltage of 3V. Do not use them directly on 12V or 16V to avoid damaging the LED. You need to connect the resistor in series, before you use them on 12V or 16V, I will provide compatible resistors for free. Please apply the correct working current of 20mA to each LED. Note: Since the above size is measured manually, the actual size of the item received may be slightly different from the size above. Meanwhile, please note that due to lighting effects, monitor's brightness/contrast settings, etc. There may be slight differences in the color tone of the photos and the actual item.
