Candles also offer wonderful sparkle and set a distinctly relaxing romantic tone. Just make sure you keep them well away from any flammable objects such as towels and hair and never leave them unattended.
Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
If your cabinets don't go to the ceiling consider adding lights above the cabinets. Using a more powerful light source such as a T5 fluorescent increases the reflectivity of the ceiling thereby increasing the light in the room. While increasing light levels is important it is equally important to minimize glare. Use matte finishes to reduce light flares and glare.
