My husband put these in his shop, using 6 in a 24' by 24' area, in two rows of 3.  He wanted to avoid fluorescent lighting; these pendants take up to a 100-watt bulb, and so provide a good bit of light, using LED bulbs for longevity.  They are very reasonably priced (especially on sale) and have a bit of a commercial look without appearing cold, perfect for a woodwork shop.
