3M ESPE Elipar FreeLight Mode D'emploi page 4

Product Description
Elipar FreeLight, manufactured by 3M ESPE, is a light
source for intraoral polymerization 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.
