I just went back and reread your original post. You ask if you could wire the
10 LED street lights in Series. Our various responses since have been
cohfusing. To clairify, You could wire them in series but the best method
would be paralell. Then you could use your Tyco power pack set to a
voltage around 6 or 7 and feed the street light bus through a 470 or so
resistor. It is not necessary to have a resistor for each LED. My complex
turnout control panel had about 15 or so LEDs all in paralell. It worked
fine. You could also use, as suggested, an old wall wart. Each has a label.
Make sure it's output is DC and has a voltage around 5 or 6 volts.

Sorry, please ignore the series wiring idea. The lights come with resistors which it says can allow them to operate between 9-16V. Without the resistors, no more than 3v but I plan on using the resistors on each light and wire them in parallel. Just need the right power source to handle about 20-22 lights like these.

I also have 10 street lights with the same components so that's why I'll have about 22.

For some reason I never thought of doing it that way. I use three power buses, each powering the next, so that wouldn't really work the way I have it wired. Wouldn't be hard to change though and might save a few minutes wiring. That said, resistors are cheap and running 12v bus with individual resistors gives more flexibility. I can run any bulb or accessory up to 12v on the same bus. 2-3v LEDs or 12v incandescents, some screw in LEDs that have resistors built in already. If I had a lot of street lamps I would probably do it that way though. Either works.

I like those lights!

Hi, have you considered these VDC buck converts, the work well, especially if you have a 12VDC buss setup under your layout, these can be setup at point of use , no need to use power supplies etc.

If you assume around 20 ma per light, that means 100 would draw around 2 amps, 20 would be less than 0.5 amps (0.4). So a 9 volt wall wort that that has a 1 amp rating would be perfect. Don't forget the resistors! If you go to a 12v wall wort, you might consider using 1k resistors, give you a little more lifetime to the LED's. Don't use the 3v no resistor option, you really need the protection of the resistor.
