The most inconspicuous lighting is recessed canister lights. Install a grid of lights spaced 6-8 feet apart, with eyeball lights for accent lighting. Install them as task lights over a countertop, and position a watertight fixture above a tub or shower.
Recessed canister lights are easy to install in finished areas. Running cable is not too difficult because lights usually space only two or three joists apart. Using a fishing drill bit, you may need to cut only a few holes into the ceiling.
Most inexpensive recessed cans are rated to use only 60-watt bulbs.
