They do attract attention to themselves, however, and give off a lot of heat, so use them sparingly. A better solution is fiber optics.

Fluorescent lighting provides the most light for the least money but has its limitations. Before making a decision about what will work best for your own project, review all the possibilities with a lighting designer, a knowledgeable interior designer or architect, or a reputable electrician.

By lighting your work, not the top of your head, you can get the light levels you need while enhancing the charm of your period kitchen.
