Small black bugs found mostly around window sill but also around lamps and...
It is difficult to make a definitive identification from this picture, but I have some ideas. First, it could be a drugstore beetle, which tends to feed on many different types of material (ie. grains, fabric, hair, etc). The larvae cause the most damage from their feeding on these materials. Treatment involves identifying infested material and heat or cold treating it to kill all stages of the life cycle. (see this website for details: http://entnemdept.ufl.edu/creatures/urban/stored/drugstore_beetle.htm For the adults I would vacuum them up, take the vacuum bag and wrap tightly in a garbage bag and throw away.
It also may be a black carpet beetle. These beetles feed off any kind of fabric or fur (even stuffed animals). Their larvae are light brown shed their skin many times, so it it sometimes easier to find their cast off skin. Treatment is similar. using a heat/cold treatment, vacuuming and throwing away bag, but you may also find a pesticide helpful. See this fact sheet for more details and follow the directions on the label. http://entnemdept.ufl.edu/creatures/fabric/black_carpet_beetle.htm If these do not seem to be the beetles, you may take a specimen to your local OSU Extension office and they can identify it for you. Good luck!
