Here is a GE Lucalox LU100 100W HPS lamp. Apparently this is UK spec. despite it saying S54 ballast on the packaging. Still almost boiled the ballast, though :-(

I can't see the etch very well but if theres a dot and dash to the right of the U.S.A. It should be Ravenna , Ohio .

There is...definitely Ravenna.

You certainly mean "world spec outside NA and Japan"... GE surely did not make this lamp specifically for the UK. The stamp on the bulb clearly identifies it as a 100 V lamp, so definitely not an S54 (55 V) type. Or was there a misprint? It would be interesting to know its voltage during operation because it shouldn't cause harm to our 100 W series-choke ballasts.

@Tim/@Eric - thanks for the information, I'll update the description.

@Max - You're right, but UK spec was easier to say Wink I'd would be interested to know why the sleeve says S54, though Wonder I'll run it up again (when I can find it..!) and check.

I wonder if it's either the wrong sleeve or possibly a typo from GE ?
