A piece of plastic got left on a bulb or on some metal that was supposed to be pealed off? Some packaging "popcorn" left inside of the light fixture?
OK, I'm being picky. You said the box was labelled for 60W. What if any, do the sticky labels on the sockets inside the light indicate? I've been suprised in the past to find 40W labels on the sockets of what I thought were 60W fixtures.
Hurry up or you'll make me mad and I'll wait on you.
Sorry for plagiarizing.
Take a look at 314.27 which states that boxes used at luminaire outlets shall be designed for the purpose.
I would argue that the wall boxes you used were not designed for the purpose, as you have found out.
As you have suspected, the boxes are wall boxes meant for switches and receptacles, not luminaires. The manufacuter's web site says they are not fire rated.
However....I am suspect that the fixtures may not be manufactured to the UL specs they are sold under. 3 60's is hot, but I have yet to see a fixture designed for 3 60's that would melt a Carlon box of any kind, ceiling or not. The price mentioned for the fixture makes me think they were made in China to sub standard specs and sold for a pittance to the unsuspecting. Combine that with mounting to a box not designed for the application and 'Huston, we've got problems'.

What isn't made in China?
assuming your men did not remove the insulation thinking it was part of the packaging, i would guess the fixture may have been rated for 3 25 watt bulbs and mislabled with a sticker saying 3 60 watt bulbs...
Have never seen or heard of this problem before. We put in some closet lights that are a 12inch light with 3 60w bulbs in them. These lights are mounted to plastic nail on outlet boxes not the round nail on boxes for lights. We come back the next day and the lights and boxes are hanging out of the ceiling because the boxes are melted and distorted enough to come off the nails. The 6/32 screws also loosened because of the heat. Anyone had this problem with these cheap plastic boxes? Could the light be causing this much heat?
There is definetley something wrong, period! In 20 years I have never seen a pvc box melt from the proper installation of a fixture with 60W lamps. To my knowledge the same material is used to produce a single gang nail on box or a round nail on ceiling box.Any type of heat that is substantial enough to melt a box is a real serious problem.There must be more to the story than is being told.
Don't ceiling boxes have 8-32 screws?
Well, the drywall screws holding the fixture bar to the blue PVC switch box didn't pull out. :roll: And, from the photo, that looks to be an insulated ceiling.
That's a style of luminaire that holds heat. No two ways about it.
Back through the Eighties, we were told, by various inspectors, not to use round blue and yellow PVC nail on ceiling boxes, boxes that were listed for luminaire support, because of this same problem.
