What I remeber about this topic is that Eddy found out that there shouldn't be any air (oxygen) in the lamp.

Wrong again Georg (slightly)

Thanks Ian!! Interesting.. As mentioned Eddy gets all the credits. Why is that? I can't remeber Joseph Swan at all? What is the point of history teaching if it is not true???

Though I don't agree with AGAIN!!!

Well the AGAIN bit refers to your total lack of acceptance that alarm cable is for alarms and nothing else will do! in the UK.

So in that sense AGAIN is very much correct regardless of wether you agree or not.

If it is ONLY related to alarm cable I agree that i might be wrong with regulations. Though I haven't yet seen the regulation that says that alarm cable is not alarm cable if it is twisted pair..

Georg, it is not because of regulations. It is the manufacturers that recommend using flexible multi-strand cable for thier equipment.

It is also due to preference. Solid core twisted-pair cable is liable to snapping.
