uh for human eyes? how far are we talking about here? is the bulb lights only focused on the object? can you see the lights from the bulbs? cause if you do, the photons from the bulb will over power the photons coming from the object.

But keep in mind that your eyes have auto dimming switch, if there is too much light going in the eyes and the object is blurred, then the iris will contract and the object become focused.

If the object is too dim, the iris can expand and allow in more lights and the object will appears to get brighter.

So this question 1v2 light bulbs has no right answer, the answer is that it all depends on whether or not you're on drugs (cause drug causes pupil to dilate (iris to expand)).
