This publication was first issued in 2003 and revised in 2005. It answers commonly asked questions about mid-wattage metal halide (MH) lamps. This revision includes new data gathered from testing conducted over a 15-month period (October 2002 to January 2004). It does not include information about any additional products. Readers familiar with the original publication will notice new information about lumen maintenance, color shift, and color variation, located in the question: "What are some important characteristics of MH lamps?" This question is complex and has been separated into several sections.
