What's this lightbulb?

It's a Cathermin tube with an indium complex of +4.

Used in an Interocitor.

One presumes you must be old enough to recall the film "This Island Earth"?

One of best, if not the best, 1950's SF film. It's fun and entertaining whilst films like The Day The Earth Stood Still are too serious. The original is excellent and the MST3000 skit is priceless.

Use your intensifier disk on YouTube to enjoy it if you don't have it on DVD. ;-)

Has it stood the test of time like Forbidden Planet?

Squirrel cage lamps were for many years the std fitment for ships navigation lights as they gave a nice even light distribution, they often move around a fair bit especially at the top of a mast so I don?t think they were that fragile.

Common on London taxis - but they used the all in one Lucas sealed beam unit, which wasn't halogen.

These days that same unit on full looks like dim dip.

I've often wondered where the title comes from. It sounds like a quotation, but I can't trace it.

Forbidden Planet is a great film but is "stiff" in comparison and whenever I see Leslie Nielson, even when he's young, I expect him to break into a Frank Drebin Police Squad routine.
