Product Description
Elipar FreeLight 2, manufactured by 3M ESPE, is a
high-performance light unit 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 a high-performance Light Emitting Diode
(LED) as the light source. In contrast to halogen light
units, the unit emits light mainly in the wavelength
range of 430 to 480 nm, e.g. 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. The polymerization
performance of this light unit is so high, that the
exposure times can be reduced by 50%, compared to a
conventional halogen light unit.
Exposure time options: 5, 10, 15, or 20 seconds
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.
Both the maxi fiber rod and the proxi fiber rod
may only be used for the mentioned purposes and
not for the polymerization of usual fillings, as
otherwise complete polymerization can not be
guaranteed.
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
approximately 10 minutes outside the charger.
In stand-by mode, the charger consumes maximally
0.75 W. Starting in 2003, this value will be recom-
mended for the stand-by mode by the EU according to
the "Code of Conduct" on efficiency of external power
supplies.
These Operation Instructions should be kept for
the duration of product use.
Fields of Application
• Polymerization of light-curing dental materials
with photo initiator for the wavelength range
430-480 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 to
confirm the wavelength range.
