Wow, it certainly helps to have a new set of eyes look at the problem.  I 
*ordered* a 600W DC power supply and never noticed the 12VAC on theose 
transformers (see what I expect to see I guess).  Thank you!  Now it makes 
sense.  I'll try one of those inverters.  

Cheers, Ian

if you will look at the different power supplies you will see the 
difference.  The LED lights require dc power (note the transformer says 
output 12vdc).  teh exisiting transformer you have is marked output 
12vac.  To use it you will need a rectifier unit to change from ac to 
dc.  something similar to these.

note, you may need to mount these on a heat sink if carrying much 
current.  according to the marking on the LED transformer you have, any 
one of these should be able to handle several LED strings, since they 
draw less than 1/2 amp.
