Five to ten 10MM LED require what power supply?
I am planning on making a LED reading light for my nephew, but I'm not sure what kind of power supply would be needed, or how long it would last.
I have bought plenty of 10mm LED's and I'm planning on using one or two per light points, with there being five light points in an 8x11 inch space.
What kind of power supply would I need for these? I was thinking of going with AA batteries, since they're readily available, but I'm not sure if I'd need one or four (put into one of those cheap battery holders, I think they're setup in series.)
Also, is there a way to do it without resisters, or would resisters be required, no matter what?
Thanks for any assistance!
