Newb question about LED Lantern Answered
Hi I have a stupid newb LED question. I'm building a camping lantern out of a lot of super brights I bought on ebay. I 'm thinking of powering it on a large 6v or possibly a rechargeable in the future. I know I need a resistor but the LEDcalc I've been using shows a schematic with a resistor on every LED. I plan on using 20 or more LEDs. Do I really need 20 resistors or can I use 1 somehow? I'm also open to better battery ideas. Thank you!!
