LED in a string/series

OK. First off this is for an Odyssey Of The Mind Project. So no one can contribute to the idea of the problem. But anyway i was wondering how to wire around 60 leds together with out using a bunch of resistors. I was wondering if you can use a buck puck.

But if you cant i need a resistor chart.

yes you can - total up the power consumed, run them in sets of 10 per ladder (to reduce current heat in the ladders), make sure you have all of them in parallel, and wire them up to the puck size you need.

Thanks. that helped a lot.

azmaria dei when u say run them in sets of 10 with the buck puck does that mean u want me to put a resistor every 10 5mm leds while using the buck puck???
