[sdiy] switching LEDS

[George Hearn]

An N Channel MOSFET will nicely switch plenty of current in a small package
if it is a good one.  The relay would only appropriate if the driving
circuit must have electrical isolation from the switching circuit.  In the
case of an LED this is not likely to be the case.  If it were say a
230V(110V) neon that needed to be powered from the AC mains and switched
from a low voltage DC circuit, yes a relay would be what you might need.

I'm basically using Ken Stones circuit to switch some LEDs on based on an 
signal input.

Now I want to switch very big LEDs like 5-10 watts, so I'm sure I need to 
add something like a relay to keep it all safe and isolated.
I guess I could use small relays, but is the best way to use some kind of 
solid state relay?

Any pointers to what there is, and what I should be looking at?


(If there's a different list this is better asked on, please let me know!)
