So I'm looking for a 6.3 ish Ohm 3 ish W resistor? ... A quick search at the local resistor store shows 5.6 and 6.8 Ohm resistors.. go slightly higher or slightly lower.. I'm thinking 6.8 Ohm 3 Watt... Am I about right on that? Thank you for the tips as always.. and I just connect it to either the + or the - wire going to the Luxeon Rebel ?
