range in size from 18W to 180W and average 14, 000 to 18, 000 hour lifetimes. They have excellent lumen maintenance but the longest warm up times from 7 to 15 minutes. LPS lamps feature the shortest re-strike time among HID sources only 3 to 12 seconds.

High intensity discharge lights are the least efficient HID light source. To move users to more efficient technologies, a federal mandate now outlaws the manufacture and importing of mercury vapor ballasts into the United States for replacement or for use in new luminaries.In the event of a mercury ballast failure
