PARs, ACLs and MRs have an
optical system
of
reflector
and lamp, usually sealed into the same
lamp
unit with a glass front which acts as a lens.
The
light source
is fixed and uses a
parabolic reflector
to produce an intense and directional
beam
of light |
|
 The
lamp
is housed in a simple can-like chassis which cuts off most of the indirect light. |
