LED power suppy help?

I am plan to run 4 leds in a seires parallel configuration. The leds have a forward voltage of 5.2 and run at 350 ma. Would it draw more power if I had a higher input voltage or would it still draw the same amout. I am trying to decide between lithium ion batteries and NMh.

What is this wiring diagram symbol? Answered

It's part of the power supply circuit and probably has something to do with the wall wart power supply, but I'm not confident enough in that explanation to move ahead with it.

I want to make a tiny hot plate

I am trying to make a hot plate about the size of a quarter to 50 cent piece. I am going to wire in a dimmer switch for temp control, I would like even heat so I dont know if nichrome is the way to go-I'd love to use some sort of flat type resistor but havent found anything on line that seems fesible. Also I would like to use a plug in power suppy. Any ideas?
