Water inside light fixture, but no leak.?

One of my inside light fixtures became very dim, when taking off the cover I noticed about 2 cups of water pooled inside.  I assumed there was a leak from the ceiling, however not only is it dry above the light, there is a layer of dry dust (sheet rock) on everything, and no indication of leaking or moisture. The light fixture itself was pretty secure, it was water tight.  The home is newly remodeled within the last year and I purchased about 6 months ago.  I though maybe condensation, but it was quite a lot of water, it would take a long time for it to build up to that level.  Again I did check the top of the fixture and ceiling above, there is absolutely no indication of a leak of any sort ever.  The only other thing I could think of, is maybe a contractor filled it up with water, possibly disgruntled?  Any advice?

    If the water is suspected as coming from a leaking pipe, turn off the water supply at the home's main shutoff valve. If there is still water in light fixtures, remove the cover of the light bulb or panel and drain away the water. Inspect the ceiling around the fixture and look for any pooling water.

         Try spraying water on it in the summer (the roof, not the light fixture). Otherwise, I would suspect someone stepped on the bathroom vent hose in the attic. Grampa  B

    Check to see that and air conditioner duct or the air conditioner drain pan is not directly above where you're having the problem that can certainly cause water drippage where the fixture is

    That amount of water must be a roof leak. It was just dried out when you observed it.

    keep an eye on it ... odds are there is a leak in the roof above and the water runs down into the light fixture.  sorry to say, finding such a leak can be quite difficult ... and the roofing contractors want major dollars to redo just the affected part of the roof  [the leak isn't necessarily where inspection of the underside of the roof shows it to be].  if this isn't your cup of tea, find a local handyman with experience in this area.  -- grampa

    If it hangs from the attack, cold air coming down through the box/fixture and condensation in the dome.
