Hey guys it's been a long time since I've done this but my nephew wants a saber for his birthday haha. I see now the shop has the lens assembly with lens led heatsink eat all ready to be wired. Can you guys tell me if I'm calculating this right if I bought the following things:

4 AA battery pack @ 6 volts
Red rebel star led lens heatsink module

5.6 ohm 10 watt resistor

Using this calculator (http://led.linear1.org/1led.wiz) I put in the 6 volts from the battery then put 2.4 volts for red diode voltage and then put to run it at 700mah it came to a 5.6 ohm resistance can anyone confirm or Deny? Thanks!
