With spot metering set on the lightbulb, you'd likely have an underexposed (assuming you're letting the AE system set the exposure without compensation) scene, because the camera assumes you want to expose for just the lightbulb.

With center-weighted metering, you'd likely be a bit overexposed, since the camera would still be considering the whole scene, but simply giving more "weight" to the pixels in the center of the frame (not just the lightbulb).

With evaluated, even (slightly) more overexposed.

In practice, though, I've found what you've found: center-weighted doesn't make much difference from evaluative for most scenes. Try testing with spot metering vs.evaluative.
