Hello all. I am currently building my first saber (Blue) using an econo board from an Obi-wan "force action" saber from around 2008-9. I plan on using this RGB LED from a French site: http://www.selectronic.fr/star-led-a...mmune-120.html and this AV switch: http://www.selectronic.fr/poussoirs-...tenu-vert.html , all powered by 4 AAA batteries and wired like so:

Normally 4 AAAs should be enough, but I can't seem to determine what resistors to buy. Using Ohm's Law as explained on this post:http://forums.thecustomsabershop.com...e-to-Ohm-s-Law, I already worked out that I need a total of 6.9 Ω and 1W. Could someone help me please?
