    I have an attic bedroom with the track lighting as shown in the photo. Above each bulb appears to be a scorch mark. These bulbs came with the track lighting fixture and are 50 watts each. Are we in danger of a fire from these lights?

    This may be an inducation of little or no insulation in the attic. These light are hot and likely cause some movement in the air. Warm moist air does carry dust and as this air is moved up past the light it runs into the ceiling and cools there leaving moisture and dust on the ceiling. If you had a smoker in the house the stains would be brownand would appear much sooner.
    Do you burn candles in the house or that room?

    Wow, Great thread, I always "knew" what it was but never really knew how to explain it well.

    Consider that you have what looks like at least 6, and maybe 8, 50 watt halogen lamps. 300 to 400 watts total.
    Incandescent lighting converts about 85% of that wattage to heat...makes your fixture more efficient as a heat source than a light source. Tape a thermometer to the ceiling after the fixture has been on for awhile to see how hot.
    Also noted that your ceiling is peaked, and very narrow, so all that heat has nowhere to go.
    While I agree there is some rafter ghosting, the black spots are likely from the paper on the sheetrock being overheated.
    I would get rid of that fixture and replace it with fluorescent or surface mount fixtures with LED A lamps.

    To be sure, turn the lights on for 4+ hours and feel the ceiling above them. But frankly I do not see these bulbs at that distance causing scorching heat. I would guess that you have the "ghosting" as mentioned above. And if heat is a problem, you could reduce it by going with fluorescent bulbs that would use 1/4 the wattage (although a bit ugly).
