2. Avoiding damage
Do not point the front of the fixture towards the sun or other strong light sources. The
front lens focuses and concentrates light just like a magnifying glass. Strong light can
cause internal damage to the fixture, melting components or starting an internal fire
within seconds.
Figure 1. Avoiding damage from light sources
Damage can occur whether the fixture is powered on or off. See Figure 1.Damage
can also occur if the light hits the front of the fixture at an angle: the fixture does not
need to be pointing directly at the sun or other light source.
To avoid problems from strong light sources:
• Do not expose the front of a fixture to sunlight or any other strong light source.
• For outdoor applications during daylight, make sure that the front face of any fixture is
shielded or points away from the sun, even when not in use.
• Avoid pointing other high-powered beam lights directly at the fixture.
Do not pick up or carry the fixture by the front lens bezel. The LCD display is also fragile.
Picking up or supporting the fixture in these spots could result in damage that is not
covered by the warranty.
Use only original spare parts. Any structural modification of the system will void the
product warranty.
Clean optical components only as directed. Oils, solvents, and other chemicals
commonly used for cleaning can damage the lens coatings and surfaces.
Do not drop the product or expose it to mechanical stress.
Do not expose the product to heat (from other lighting fixtures for example).
Transportation and storage
Transport the impression FR1 either in a flightcase or in its original packaging to protect
the fixture from damage caused by shocks during transportation.
Store the fixture in a dry location when not in use.

4. Product features
The impression FR1 from GLP is a high-quality moving head lighting fixture with a
60 watt RGBW LED and advanced optics that give a powerful, homogenous and
sharply defined beam throughout the fixture’s 10:1 zoom range. Advanced German
design allows exceptional performance and a versatile feature set to be packed into
one of the most compact moving head lighting fixtures currently available, with GLP’s
familiar baseless format. The fixture is designed for ease of installation, with Neutrik
PowerCON IN and THRU connections allowing daisy-chained power lines.
The impression FR1 is designed for permanent or temporary indoor use. It can be used
outdoors if it is protected from moisture and precautions are taken to prevent damage
from direct sunlight. It may be placed upright on a level surface or suspended from a
suitable structure as described this manual.
The impression FR1 is not suitable for household use, for use in any location where
unattended children have access to it, or for use in permanent outdoor installations.
Light source
The impression FR1 is equipped with an OSRAM Ostar RGBW LED with a rated lifetime of
50 000 hours.
Removable micro-Fresnel lens
A detachable micro-Fresnel lens is fitted to the front of the fixture to give a smoother
beam. It is possible to remove this lens to obtain a harder-edged beam (see page 27).
Pan and tilt
The impression FR1 pans through 540° and tilts through 220° with coarse and fine
control channels and self-correcting position feedback.
Pan and tilt position feedback can be disabled using the control panel or the Settings
DMX channel.
The direction of pan and tilt movement can be reversed by selecting Invert command
using the control panel or the Settings DMX channel, and you can also swap pan and
tilt via the control panel. Inverting and swapping movement is a fast way of obtaining
symmetrical effects without reprogramming at the console.
The default settings for position feedback, inversion and swapping are OFF.
Continuous (endless) pan rotation is also available on a separate DMX channel.
Color
The impression FR1 provides both color presets and 0-100% continuous RGBW color
mixing.
You should normally set RGBW levels to 100% when you begin to use the color presets
channel, but after you have selected a color on the color preset channel you can
fine-tune it using the RGBW channels.
10 impression FR1 User Manual
German Light Products
CTC
The CTC DMX channel lets you adjust color temperature from 2500 to 10 000 K.
You should normally set RGBW levels to 100% when you begin to use the CTC channel,
but after you have selected a color temperature on the CTC channel you can finetune it using the RGBW channels.
Shutter effects
The impression FR1 features an electronic dimmer / shutter system that provides pulse
and strobe effects.
Dimming
0 – 100% continuous dimming is available.
Light
output
DMX control value
Figure 3. Dimming curves
See Figure 3. You can select from three different dimming curves using the control
panel or the Settings DMX channel: Linear, Soft and Extra soft:
• Light output using the Linear curve will appear to increase and decrease evenly
throughout the dimming range.
• The Soft and Extra soft curves give finer control at low light levels (where the eye is
more sensitive to changes in light level) and coarser control at high levels.
The default setting is Extra soft.
Fan modes
The four different cooling fan modes give you a range of options to choose from
depending on how much you want to give priority to high-intensity light output or to
low fan noise:
•Fan regulated gives priority to light output. If the fixture is blacked out, fans run at
minimum speed. When light output intensity is increased, temperature regulation
impression FR1 User Manual 11
www.glp.de
increases fan speed to the level necessary to keep the fixture at optimum
temperature.
If light output is set to maximum intensity but the fans can keep the fixture at optimum
temperature, there will be no regulation of light intensity. If the fixture begins to
exceed optimum temperature, light intensity will be reduced until optimum
temperature can be maintained.
•Fan constant high mode is optimized for maximum light output and suits operation in
high ambient temperatures. Fans are set to constant operation at high speed and
light output intensity is regulated in order to keep fixture temperature at optimum
level.
Besides maximizing light output in high ambient temperatures, you can use this mode
to cool down a fixture quickly or to remove dust from cooling fans.
•Fan constant medium mode is suitable for low-noise operation in normal ambient
temperatures. Fans are set to constant operation at medium speed and light output
intensity is regulated in order to keep fixture temperature at optimum level.
•Fan constant low mode is optimized for minimum noise. Fans are set to constant
operation at low speed and light output intensity is regulated in order to keep fixture
temperature at optimum level.
This mode gives an extremely low fan noise level, but if you use it in high ambient
temperatures there may be a noticeable reduction in light output intensity.
In all fan modes, if fixture temperature reaches a dangerous level, LEDs will be shut
down for a period until the fans have brought the temperature down to a safe level.
You can set the cooling fan mode using the control panel or the Settings DMX
channel.
Zoom
The impression FR1 has a 10:1 zoom range. You can narrow the beam angle from 35° in
flood mode to 3.7° in spot mode.
Zoom can be inverted from flood spot to spot flood using the control panel and
the Settings DMX channel. The default setting for zoom inversion is OFF.
Control panel
The control panel on the side of the yoke has a backlit graphic LCD display for setting
up the fixture and changing fixture settings. See ‘Control menu layout’ on page 19 for
a table showing the control menu structure and options available.
PWM frequency
You can change the LED dimming PWM frequency using either a DMX command or a
control panel setting in order to avoid flicker and beat frequencies in video images.
The default PWM setting is 582 Hz. You can adjust the PWM frequency continuously
from 582 to 618 Hz, or you can set it to either 1200, 2400, 4800 or 9600 Hz. Note that a
higher PWM frequency may affect dimming performance.
12 impression FR1 User Manual
German Light Products
The PWM frequency setting is stored in the fixture and is not affected by cycling power
off and on. However, it will be affected if you use the Factory default command in the
control menus.
You should set all the fixtures in an installation to the same PWM frequency in order to
ensure the same performance. As described above, you can do this using the PWM
frequency selection or Factory default commands in the control menus or using the
PWM frequency DMX channel.
Installation options
The base provides M10 threaded holes for direct fastening of half-coupler clamps. A
countersunk M10 bolt for clamp attachment is supplied with the fixture.
Two eyelets are provided for safety cable attachment.

See Figure 4. Fasten the bolt through the rigging
clamp into hole A in the center of the base of the
fixture so that the rigging clamp is held securely.
You can also install narrow half coupler clamps
through holes B, but these extra clamps are not
necessary.
Fasten the rigging clamp securely around a chord
on a rigging truss or similar bar.
See Figure 5. Attach a safety cable to one of the
safety cable attachment points in the fixture base
and loop it around the truss chord or bar so that it
will hold the fixture if the rigging clamp fails. Take
up as much slack as possible in the safety cable
(by looping it more than once around the truss, for
example).
Make sure that the head will not collide with
another fixture or any other object when it tilts
and rotates.
Figure 5. Safety cable
attachment
Placing on a surface
You can stand the FR1 upright on its rubber feet on a flat, stable, horizontal surface.
If necessary to prevent the fixture from moving if the surface is slippery or falling, pass a
ratchet strap, webbing or other bracing strap through the safety cable attachment
points (see Figure 5) and fasten it to secure anchoring points.
Make sure that the head will not collide with anything when it tilts and rotates.
Connecting to power
The AC mains power supply must include a connection to ground / protective earth. It
must be protected against ground / earth leakage and overload. The autosensing
power supply accepts AC power at 100-240 V, 50/60 Hz. Do not connect the fixture to
power at any other voltage or to an external dimmer.
The FR1 does not have a power ON/OFF switch. Power is applied to the fixture as soon
as the power cable becomes live.
The impression FR1 has a 3-conductor Neutrik PowerCON socket that accepts AC
power from a Neutrik PowerCON female cable connector.
Important! PowerCON connectors do not support hot-plugging. Shut down power to
the power cable before you connect it to the fixture, or you may cause arcing and
deterioration of the contacts at the connector.

Percentage values are calculated by dividing DMX values by 2.56 and rounding to the
nearest 0.1%.
To apply a command on Channel 14 (Settings), start at a value of zero, then move to
the required value and hold it for at least 3 seconds. If you move to the required value
from any other value than zero, the command will not be applied.
To adjust the PWM frequency using the Settings channel, start at a value of zero, move
to the required value and hold it for at least 5 seconds.

9. Service and maintenance
Warning! Read ‘Safety’ starting on page 3 for important safety information
that you must understand before you service the fixture. Work in well-lit
conditions. Do not look directly into the light output.
Maintenance
Suggested maintenance intervals
The cleaning schedule depends on the operating environment. The intervals below are
suggestions from our experience with typical installations. Adjust as necessary.
Maintenance Task Interval How
Clean front lens Weekly
Clean fans and air channel Monthly
Lubricate zoom rails Yearly
Wipe with soft cloth and glass cleaning
fluid.
Use soft brush and vacuum cleaner,
compressed air, etc. Hold fans still with pen
or screwdriver to avoid spinning them with
vacuum or air jet.
Apply very small quantity of Klüber Barrierta
to rails.
Cleaning
impression FR1 components require occasional cleaning to prevent the buildup of
dust, dirt, and smoke fluid residue. Pay special attention to the air vents and front lens.
Failure to keep the fixture clean will significantly reduce light output and may cause
damage. Do not let optical parts come into contact with oil or grease or touch with
bare fingers.
Regular cleaning will ensure the maximum performance and reliable operation. The
lenses and glass gobos may be cleaned with alcohol wipes or a soft cloth moistened
with isopropyl alcohol.
Wait until all parts are dry before operating the fixture.
Lubrication
The only parts that may require occasional lubrication are the focus/zoom rails.
Contact GLP Service and Support for advice.
Removing and reinstalling the micro-Fresnel lens
If you would like to obtain a sharper-edged beam, you can remove the micro-Fresnel
lens that is installed in the front of the head (bear in mind that this will result in a slight
loss of evenness in the beam projection). The lens is held by three screws. A frost filter is
installed immediately under the lens.
impression FR1 User Manual 27
www.glp.de
To remove the micro-Fresnel lens:
Shut down power to the fixture and allow it to cool.
Figure 8. Removing a micro-Fresnel lens
See Figure 8. Remove the three Phillips #1 screws (arrowed) from the lens in the
front of the head.
Tilt the head downwards and allow the lens A and frost
filter B to slide out of the head. Store the lens for possible
re-use.
Reinstall the frost filter in the head by passing the three
screws through the notches in the filter and tightening
them into their holes in the head.
If you reinstall the micro-Fresnel lens later, use the three
Phillips screws to fasten it into its original position over the
frost filter. See Figure 9. The smooth side of the lens must
face inwards and the ridges must face out of the head.
