Hi there.

When considering a fixture's size and position, it's often helpful to consider the length of your counter or island space, placing the pendant at a height where the continued downward angles of the fixtures sides will hit the ends of the counter space. This rule of thumb can work for single or multi-pendant fixtures. Height is recommended to be low enough to provide adequate light to see what you're doing but high enough to be out of the way. Customizable length fixtures are a great option for this scenario. Various custom styles, lengths and sizes can be found at www.rejuvenation.com.

For wattage, think in terms of lumens rather than wattage...general kitchen lighting lumen recommendation is 40 lumens per foot while task kitchen lighting recommendation is 80 lumens per foot.
