Question DIY moonlight help, please.

I am planning on getting these 10mm Blue LED Lamp 10000 mcd. Then thinking of adding these 5mm White LED Lamp Light 5 MM Bulb Mcd Resistors. Also have 150 Ohm Resistors 1/4W.

The plan is to have 6 blue lights in the back and a row of 5 white. The white will be space so to be between the blues. Is this a good idea? I found this schematic that has 2 rows and a resister at the end. Will this work for these LEDs?

it depends on your power source. For batteries, yes.
If you're plugging this into the wall, you'd need an 14V DC adapter.

You might as well just use that setup. It will dim your lights a little, which might be desired. You definitely don't want bright moon lights; a faint glow should more than suffice.

11 led x 3.2 V = 35.2V @ 20ma (as stated on the LED)
That's how many volts you need for your series setup.

If you don't mind a dimmer than usual look you can use the 12V adaptor. For sure, you won't over heat or blow anything up.

According to this calculator
I can run 12 LEDs with 9v and R120.
What would happen if I used R150 instead. They would be 6in apart.


or
I can run 10 LEDs with 6v and R150. They would be 3in apart.


Which 1 would be the best for moonlight affect?
Can I use a push on switch?
