Hi Andrew and all,

Some time ago, after hearing this oft' repeated assertion that 
flouro's use a lot of power to start, I decided to test the claim for 
myself.

I have a clamp meter at the workshop for testing the loading of AC 
electric motors running air compressors etc. With the clamp meter set 
on the most sensitive setting (I can't remember the full-scale amp 
setting but it was certainly adequate for the task) I found that 
flouro's don't use more power to start than when they are running. So 
feel free to use them as energy savers, but don't run them over 
rotating machinery. The strobe lighting effect can make a rotating 
and dangerous machine look like its stationary. The newer high 
efficiency flouro's don't suffer from this problem because they can 
be cycling at up to 25k, as opposed to the older styles which run at 
the 50 or 60 hz of the power grid supply.
