Forum:SH Archive/Lightsaber power packs

Wookieepedia &gt; Senate Hall &gt; 

How long were they used? I read on the Light saber page that the first self contained lightsabers(no packs) showed up around 5,000 BBY, but on the same page it has a picture of Vima-Da-Boda holding a modern lightsaber and it says the saber was made 10,000 BBY. So whats the deal?
