Abstract
Film set lighting requirements can be met with a relatively small number of lamp head modules which are assembled to any of several different reflectors to make up combinations of lighting fixtures as the need arises. The lamp head module has integral ultraviolet protection provided by a close fitting transparent lamp cover so that HMI lamps may be safely used without other UV protection on the interchangeable reflectors. An HMI lamp igniter is provided in the housing for powering different lamp wattages. The lamp head module is wired to power either incandescent or HMI lamps depending on the power cord connector used. The lamp head module is sealed for use in wet environments including underwater use.
