A line voltage system is one that you simply plug into an outlet and are ready to go. Line voltage systems are usually easier and cheaper than low voltage systems, yet, both have their advantages and disadvantages. Line voltage fixtures tend to be larger and heavier than the smaller, trimmer, low voltage systems. Weight and size is a huge consideration for craft show applications. A low voltage system requires a transformer to step the line voltage electric down from 110 volts to 12 volts.
Some transformers are quite small and affordable, while others are very large, heavy and expensive.
Make sure you know exactly what you are getting before you buy a low voltage system. Most of the experts I spoke with advise getting low voltage systems for many applications, because of weight, size, heat, modular effect and quality of light. Part I provides tips for identifying the appropriate lighting needs for the work on display. Part II will address some of the more technical aspects of display lighting, including bulbs and how the right bulb will work specifically for your display, as well as how much a lighting system will cost. B ooth lighting is probably the most important aspect of booth merchandising.
