I'll answer ya. The toy lightsaber only have lightbulbs in them. They are either lit or not. There is no charge up light. The Darth Maul light saber only had strobe lights, to make flashes, but had removable blades, so you could "Display" it if you didn't mind the girls coming to visit and seeing it on the tv. I have this one and Dath Vader's. They all make charge up and charge down sounds as well as a hum while running. They also will crash when hit, but hitting too hard will pretty much wreck the blades after too long. But they are kinda crappy to begin with. I.E. "Toys". There are replicas that can be bought for a large sum that are display quality. Best bet for fencing, get someone to turn you one on a lathe and screw a green mop handle into it. I don't know if the new toys do any of this. They come in toy packs and frankly don't look very good. Hopefully they'll come out with some cooler ones for 'Clones. Hope all that helps. I'm a little embarrassed to realize I know that much about light sabers. But they are the absolute coolest thing to come out of the star wars universe. If you wrote this just to see what nerd would respond, you should be quite satisfied.
