Halo Energy Sword
Now you can own a real Halo Energy sword just like the one you use in the games. This is a fan made replica that actually lights up and makes sounds. LED lights make the sword shine and you can select from five different colors. The sword will also make cool crackles and hisses sounds while you move it around. This is a expensive replica but it is a awesome sword to own and perfect for Halo cosplay.
