The 3801 Limited vintage saloon carriages are to be equipped with Marinebeam A45 LED bulbs.   This tour company, which operates a fleet of vintage locomotives and beautifully restored carriages, was looking for a multivolt LED bulb that wouldn't spoil the aesthetics of the vintage cars, but could handle the wide voltage range (18-32VDC).  The cars have internal generators, whose output voltage is based on the speed of the train!  

After a worldwide search and months of testing, they selected the frosted A45 Edison LED bulbs from Marinebeam.  We produced a custom bulb with a B22 Bayonet Base (Australian Edison), and special electronics to match their needs.
