[modeleng] Re: Low voltage lighting

Hi Ron

I have a story to tell about lo volt lighting, which will explain my flippant 
remark:

Last year I bought a lathe with 3-phase electrics and included was a Lo-Volt 
light run through a
440-50 volt transformer.  I am running the lathe through a 1 - 3 phase 
inverter, so the lighting
transformer isn't connected.  In my electrical wisdom I bought a 25 volt bulb 
(standard 2 pin BC)
from The Electric Light Bulb Company.  My thinking was that 220v = 1/2 x 440v 
so that a 25 volt
bulb run off 220volts should be the same as a 50 volt bulb run through 440 
volts.  Not so.  The
bulb glowed dimmer than a TochH lamp!  

So I went out and bought a Halogen machine lamp instead!  Instant cure.

Anyone need a 440v - 50v Lo-volt Machine light?!

Regards

Dave
