This Philips 400 watt mercury vapor lamp has the current ED shape which superseded the Westinghouse BT-37 shape back in 1988, and looks much like the much older Norelco 400 watt mercury lamp shown elsewhere on the HID page, although the internal structure design is different in this one and the Norelco one.
