Ushio Light Bulb washed up at Manchester State Beach

A 12 inch long Ushio 110 volt, 500 watt light bulb washed up at Manchester State Beach recently and was found by Gary Humfeld. It has Asian characters on it.

I've been told it might have come from a ship. Again, any information you can give us to further our knowledge would be much appreciated! Isn't amazing the light bulb is intact?
