I've come across wiring a single LED light to a battery but am looking for some help wiring 3-4 to a battery. I have a lot of things in my haunt that need actual electricity, so I'm trying to cut down on the number of things I'm plugging in by illuminating some things with battery operated LED's.

Any help would be great!

Here's the calculator I use when planning on a multi led array - http://led.linear1.org/led.wiz

the leds that you are powering come in different voltage rateings. The color makes a difference. If you look up forward voltage for lets say a red led it would be 1.8 - 3.3v but a blue led would be 3.3v

the best way to do led lighting is to buy prewired 12v leds from ebay and use a power supply from a old computer as the power source. You can run thousands of leds off of one power supply.

i know you want to use batterys to run the leds but batterys are high. We use this power supply in are haunt all the time. Very reliable.
