It has always been my childhood dream to construct a lightsaber. I have found all the parts I need online, but I have a few questions that I would love your help answering. Firstly, I am getting a Luxeon Rebel Tri-Star LED from http://www.luxeonstar.com/SinkPAD_c_4699-1-1.html with a 700ma buckpuck. I found a 20mm Triple Optics For Rebel LEDs, but I do not know what beam I should choose (Narrow, Wide, Medium, or Elliptical). On to my next question: I am planning on getting a Canadian TrustFire Protected 3.7V 900mAh 14500 Lithium Battery with a Nitecore D2 universal smart charger, and was wondering if it was a good choice. And if so, what should I use to hold the batteries inside of the lightsaber hilt. I have an 11 inch long hilt and do not plan on adding sound. I am also planning to use a 32 inch Infinity V4 Saberforge blade. I am willing to take any suggestions. All help is appreciated!
