Electronic parts made by Sakatsu, non-scale No soldering required, 5 light bulb LEDs with a chip size of 3.2mm x 2.8mm (thickness is approx 3mm including leads), all pre-wired and ready to use! 3 x AAA batteries (not included) provide up to 36 hours of continuous light! (Battery life may vary and is not guaranteed.) The length of the lead wire is approximately 30cm for each of the 5 LEDs and 1 switch, making them easy to place. (Power supply board size: 50mm x 75mm) LEDs are ideal for use in models as they save power, have a long life and generate very little heat compared to bulbs. The chip LED has a manufacturer's nominal light diffusion angle of 120 degrees, allowing it to project light over a wider area than a typical bullet-shaped LED (40-60 degrees). Note: Specifications are subject to change without notice. Information edited by Sakatsu Gallery This is a pre-wired chip LED for use in building models. With 3 x AAA batteries (not included), the 5 LED's will light up quickly and brightly. If you want to light up in other colours, or want to light up with more LEDs, we recommend the Sakatsu LED system! light bulb color White (fluorescent colour) green Blue Easy LED Series Bulb Color bulb color fluorescent colour
