Using Lowel Fluo-Tec Front Accessories
Front Accessories
Intensifier:
The mirrored Intensifier, when attached,
can almost double the light output of the
fixture. Assemble before attaching to light.
Intensifier is a one piece unit that unfolds
and locks together at its corners. Take care
to make sure that all quarter-turn locks are
securely fastened. Slide assembled intensifier
into front slot of fixture, close doorflap
and secure twist-locks Note - Intensifier has
grooved slot on front for attachment
of Honeycomb Grid to trim light.
Choose correct size of Honeycomb Grid.
Gel Frame:
For using colored or diffusion gels in front
of the fixture to change the color of the light
or to diffuse it further. Slide the pre-cut gel
material into the hinged frame, taking care
to trim any excess that falls outside the frame.
Slide the frame into the slot closest to the
lamps on the front of the fixture. Close &
tighten locking door-flap.of the fixture.
Honeycomb Grid:
Each fixture has 2 options for using honeycomb grids to control the spill of the light,
either placing a grid on the front of the fixture,
or attaching one to the front of the Intensifier.
Because the front of the intensifier is a different size & shape than the front of the fixture,
there are specific models for each use. It is
not possible to use the “front of fixture” grid
with the Intensifier installed. The grids are
available in black with 20, 30, or 40 degree
dispersions. If you are at all unsure of
which honeycomb to use, contact us.
Honeycomb Grids cause some loss of light
output (see chart).
Egg Crates:
for controlling spill. Slide the Egg Crate into
the front accessory slot. Less control than
Honeycomb Grid, with less output loss.
Barndoors:
For trimming spill of the light, slide Barndoor
assembly into front slot on fixture, close doorflap and secure twist-locks. Open doors and
adjust for proper trimming of spill. Do not
operate unit with Barndoors closed.
Slide-in Slots
There are 2 slots in front of the fixture
for slide-in attachment of Front
Accessories.
Slot ASlot B
Slot A
closest to the lamps is for slide-in attachment
of the Gel Frame accessory
Slot B
furthest from the lamp is for attachment
of all other accessories.
Slots are accessible by releasing
the twist locks and opening the door-flap
on the front left side
The following available Front

front of the fixture:
n Gel Frame (supplied),
n Egg Crate Grid,
n Honeycomb Grid (front of fixture model),
n Intensifier (except Model 250cy),

the twist locks and opening the
