This photo shows you what the recess lighting in your home looks like on the other side of the ceiling. This can light has the bulb inside that one can view from the living space below. When can lights are left exposed, they become a fire hazard. As you know, light bulbs have a tendency to heat up, and if you are using the incorrect bulb, or an older technology bulb, they can heat up so much they will catch something on fire. Comfenergy comes in after this photo was taken and insulated the can light and covers it to eliminate this risk before insulating the rest of the attic. This can be seen in the following photo.
