RE: LED rules of thumb

12V is fine for outside - regardless of current capability.  Just make
sure
you put the transformer _inside_ the house!

As for killing you - yes, the amps do kill you, but it needs a decent
voltage to "puncture" under the (relatively) dry skin to the much
more
conductive goo that's inside us humans, IIRC.  That's why the industry
/
standards bodies have deemed any voltage under 50V to be "Safe Extra
Low
Voltage" (SELV).

Looks like enough then!  I shouldv remembered that calc from my
GCSE
Physics.  What a dumb ass I am :-).  Is 5 amps going to be safe
for
outside?  Always thought it was the amps that killed you and not
the
Volts??

Thanks again

Oh and by the way, Thanks to Kieran for getting me these great LEDS.
Eeryone in the office cant wait to see them installed!
