If you don't mind surplus --
The Vicor 5V/40A supplies at Electronic Goldmine are
9.25"L x 2.5"W x 1.37"High and are selling for $40 each. See
http://www.goldmine-elec-products.com/prodinfo.asp?number=G16217
This supply is trimmable. For LEDs adjust the voltage just above the Vf(max)
spec. You will have a very efficient solution.
