I had a dual 20 watt Japanese fixture from around 1960 which I got when we were on Okinawa. I was in the 7th grade. I found I had to really move the sockets to get USA made bulbs to fit. Lucky I had some Toshiba and some other brand bulbs that lasted a long time. It used screw in starters.

When I was selling lamps in New Zealand we had a company next door who owned and serviced a lot of amusement parlour machines from Asia. They would bring in these odd length Japanese tubes with E17 base screw-in starters but all we could sell them was an off-the-shelf 1x18w T8 switch start batten to replace the Japanese one. Sometimes they would buy a 110v to 240v step-up transformer to put in the fitting as that was easier than rewiring the supply to the fitting; the machines had a 240v to 110v transformer in the base of them.

Traffic signals & street lighting engineer. Please bring SOX/LPS back Downunder!!

I've one spare in a factory. It's a 20W T10 580mm tube. I wonder if this would work on our 18/20W ballast?
