ERS gets its name because it uses a
a section of an Ellispe and contains 2 focal points
plano convex lenses
the ERS optical system uses 2
a reinvented, re engineered, ERS
the HPL 575w or 750w compact tungsten filament lamp
lampis very efficient and produces an intense light from a very small area of the filament
it contains a fresnel lens diameter that tells if its a 6" or 8"
fresnels gets its name because
the focus beam the fresnel uses is a
spherical reflector that is mounted on the sliding tray
fresnel (sliding the focus tray 2wards the lens cause the light beam to
fresnel (sliding it back 2ward the reflector causes it to
500w, 750w meduim focus
6" fresnels can use
1000w, 1500w mogul pre focus
par 64 is called
the 64 in par means the lamp has a (blank) diameter
produces light similiar to par 64
s4 rotate lens and not (blank) to focus
s-4 par unlike (blank) the diff. between the reflector, lamp, and lens never changes
similiar to both s-4 par and fresnel
like (blank) uses hpl 575w or 750w
uses parabolic and mulifaceted reflector like
like (blank) the parnel is designed to change the radius of the light beam. it does this by means of a patented wave lens system
