To remedy the problem and make your home more inviting, increase the wattage in your lamps and fixtures. Aim for a total of 100 watts for every 50 square feet.  Then install dimmers so you can vary light levels according to your mood and the time of day.  This is a relatively simple project for a do-it-yourselfer, or you can hire an electrician for a couple of hours to do several at once.  And while you're at it, be sure to replace dingy, almond-colored light-switch covers with crisp white ones. New covers cost less than a buck apiece and are a quick, easy update.

Don't depend on just one or two fixtures per room, either.  It's just as important to layer lighting as it is to have sufficient wattage.  Make sure you have three types of lighting: ambient (general or overhead), task (pendant, undercabinet or reading) and accent (table and wall) lighting.  A combination of overhead, floor, table and accent lighting creates great ambience.  And having lights on different planes provides good illumination and makes the room interesting." 

One thing that's always in the bag of tricks is uplights. You can buy one for as little as $5 at home improvement stores and hide it behind a potted plant. It creates incredible drama.  Another hint: Place mirrors, silver or glass bowls or other reflective objects near lamps to bounce light around the room and make it glow even more.
