Product Description
Elipar FreeLight, manufactured by 3M ESPE, is a light
source for intraoral polymeri
zation of dental materials.
The unit consists of a charger
and a cordless handpiece
powered by a rechargeable battery. The unit is designed
for use on a table and cannot be wall-mounted.
The unit uses Light Emitting Diodes (LEDs) as the light
sources. In contrast to halogen light units, the unit
emits light mainly in the wavelength range of 440 to
490 nm, i.e. the relevant range for camphor quinone-
containing products.
The optimal match of the wavelength range to the
intended purpose ensures that the polymerization
performance is similar to that of halogen light-emitting
units, albeit at lower light intensity. This is associated
with a desirable by-effect in that the operator is
exposed to less glare.
Exposure time options:
• 10, 20, 30 or 40 sec
The charger is equipped with an integral light intensity
testing area.
The device is shipped with a turbo light guide with an
8 mm diameter light exit. It is not permissible to use
the light guides of other units.
The ‘maxi fiber rod’ with a diameter of 13 mm for
larger areas, e.g. for fissure sealing, and the ‘proxi
fiber rod’ with a point-shaped light exit, e.g. for use
in interproximal areas, are available as accessories.
The handpiece is equipped with a “power-down”
function to minimize the unit’s energy consumption.
The handpiece switches to “power-down” mode once
it is placed in the charger or if left unused for approx.
10 min outside the charger.
In stand-by mode, the charger consumes maximally
0.75 W. This corresponds to the power consumption
recommended by the European Commission pursuant
to the “Code of Conduct” for stand-by operation
(from 2003).
Fields of Application
•Polymerization of light-curing dental materials with
photo initiator for the wavelength range 440 - 490 nm
- Though the majority of light-curing dental
materials are responsive in this range of
wavelengths, you may wish to contact the
manufacturer of the material in question.

Start/Stop button
E Activate the light by briefly pressing the Start button.
- Initially, the LEDs show the preset exposure time:
4 illuminated LEDs represent 40 sec of exposure
time. After every 10 sec of exposure, one of the
LEDs is turned off, i.e. 3 LEDs correspond to
30 sec of exposure time remaining, 2 LEDs to
20 sec of exposure time remaining, etc.
EIf it is desired to turn off the light before the preset
exposure time has completely elapsed, this can be
done by again pressing the Start button.
Positioning the Light Guide
ERotate the light guide into the optimal position for
polymerization.
E To make full use of the light intensity provided, place
the light guide as close to the filling as possible.
Avoid directly contacting the filling material!
- Keep the light guide clean at all times to obtain
full light intensity.
- Damaged light guides substantially reduce the
light power and must be replaced immediately,
sharp edges may cause serious injury!
Removing and Inserting the Light Guide from/into
the Handpiece
ETo remove the light guide from the handpiece
strongly pull towards the front of the device.
EPush the light guide into the handpiece until it snaps
into position.
Measurement of Light Intensity
The light intensity can be reliably determined only
with the charger of the Elipar FreeLight unit! The light
testing area is situated in the area of the charger
accepting the handpiece. Because of differences in the
light sources used and arrangement of the components,
determination of the light intensity with the light testing
components of other units yields erroneous results.
Caution!
Measure the light intensity with the turbo light guide
only!
EClean the test area with a wet cloth, if required,
taking care not to bend or damage the charging
contacts!
EWithout applying pressure, place the light guide on
the test area such that the light-emitting opening of
the rod is level with the test area.
EActivate the lamp by pressing the Start button.
- All 5 blue LEDs come ON for approx.1sec.
- After this period of time, the number of illumi-
nated LEDs is indicative of the measured light
intensity: 5 LEDs =100%, 4 LEDs = 80%,
3 LEDs = 60%, 2 LEDs = 40%, 1 LED = 20%.
Exposure times of 10, 20, 30, and 40 sec are available.
EThe adequate exposure time of the product at hand
is stated in the product’s Instructions for Use.
ESelect the exposure time by pressing the button in
the dark-blue field.
- The selected exposure time is indicated by the
4 green LEDs.
- Each time the button is pressed, the setting
advances to the next (higher) value; from 40 sec
the exposure time setting returns to 10 sec.
Keeping the button depressed the display scrolls
through the available settings.
- While exposure is ongoing, the button for
selection of the exposure time is deactivated.
Activating and Deactivating the Light

EIf the light intensity is below 80% - fewer than
4 LEDs are ON
- check the light guide for contami-
nation or defects.
EProceed as follows:
(1.) Clean the light guide, if contaminated; please
refer to the section on “Care” or
(2.) replace the light guide, if defective, or
(3.)
if (1.) and (2.) fail to improve the situation, please
contact the 3M ESPE Customer Service or your
retailer.
Low Battery Charge Display
After frequent use the battery charge of the device may
drop to below 10%, so that only a few more exposures
can be performed without re-charging. Low battery
charge is shown by several means:
- A short audible alarm is emitted 5x at the com-
pletion of an exposure, and repeated thereafter
whenever any button is touched.
- The 10-sec-LED of the handpiece begins to flash.
EThe handpiece should be placed in the charger as
soon as possible to re-charge the battery.
Power-Down Mode
Once the handpiece is placed in the charger, all internal
functions and LEDs are automatically turned off as the
handpiece switches to power-down mode.This reduces
the power consumption of the rechargeable battery to
a minimal level. Outside the charger, the handpiece is
also switched to power-down mode if left unused for
approx.10 min.
ETo terminate the power-down mode press one of
the two buttons.
- The power-down termination signal (two short
audible signals) is emitted indicating that the
