I have a structure that I want to add lighting. I plan to use a wall wart and LEDs The wall wart has output reading of 12VDC, 100mA. The LEDs I plan on using will be Miniatronics Yeloglo. Is this going to enough power? What guage of wire would be best? I have some 18 guage that I have used to re-wire my lawn mower trailer.
Thanks in advance.
How many LEDs Will? Will they be in series or parallel?
18ga is MORE than enough for this application.

Thanks Karl for the reply.
These will be wired in parallel. I will probably wire thes in parallel. I thought the 18ga would be overkill. I just came across the wire the other day and thought it would work since it is free.
Max current for LEDs is 20ma at about 2 volts across each LED.
If in series, you could have maybe six LEDs.
In parallel with a 1k resistor on each LED, about 10 LEds.
Most use 1k resistors for LEDs which allows about 10ma at 12 volts which is plenty bright.
Go for at least a 1 amp wall wart minimum. Most wall warts are not regulated. The actual voltage will be dependent on how much current is flowing.

Is there a wall wart vendor somewhere online?
Radio Shack is online and maybe local to you.
I have used the below one.
