What's the difference in a volt-amp and a "regular" amp?

I have a transformer that makes 24vAC, and is rated at 40 VA, but the amp
rating is only 1.67.

I have a lamp (fiber optic system) that takes 24v and 250W, which works out
to 10.4A. The VA rating does not give me the current I need, and when I plug
the light in, the voltage drops because the draw exceeds the power by a wide
margin.

http://en.wikipedia.org/wiki/Volt-amp is a starting point. To avoid
recapitulating what's explained better and in more detail elsewhere,
volt-amps and WATTS (not "'regular' amps") are the related
measurements.
