The free standing light tables we sell are great for tracing art work, overlaying blueprints and maps, comparing old drawings with new drawings, as well as tasks like sorting photo slides. Some models feature LED technology for brighter and longer lasting bulb life. These are large light tables made for the professional user which come in handy within many Architectural, Engineering, and Construction work environments. Gagne and Mayline both make quality and professional-grade light tables. We always suggest that you consider the manufacturers warranty length, and type of bulbs and materials used when deciding on which model to buy.
