Light industry is industry that is usually less capital-intensive than heavy industry, and is more consumer-oriented than business-oriented (i.e., most light industry products are produced for end users rather than as intermediates for use by other industries). (Wikipedia)

Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities (such as heavy equipment, large machine tools, huge buildings and large-scale infrastructure); or complex or numerous processes. (Wikipedia)
