Why is the lamp end of the Arc-P that I just got for Christmas a different color than the body? It makes me think the wrong lamp end may be on there and that it might not be the Arc-P DS that it's supposed to be. The inscription on the body says Arc-P but it's obviously not the same color. How do I know for sure that I have an Arc-P DS when I don't have other Arcs to compare it to? (Sorry about the pic quality; it's a camera phone.)
