Built-in LED curing lamp Starlight S SLER®

Starlight s sler® - built-in version for a better curing result 

sler® stands for „soft light energy release”, a slow decrease of light intensity at the end of the cycle. This patented mectron technology modulates and controls the temperature and shrinkage of the composite, improving its mechanical properties.

Starlight s sler® - built-in version for flexible use

Polymerization with more than 1.400 mW/cm2. The starlight s sler® can be easily built into a dental unit. All the high tech electronics of starlight sler® are integrated in just its handpiece. Easy installation on your dental unit: only power supply and control are needed. The ergonomic handpiece can be positioned simply in the quiver (its holder). starlight s sler® is equipped with 6 different operating modes.

The light-curing light Starlight S SLER® is easily integrated into the dental unit: only power and regulation are required. All high-tech electronics Starlight S SLER® is located in the housing of the lamp handpiece.

There are 6 different light curing modes.

Standard effects

Temperature and shrinkage exhibit an inverse relation. Interrupting light exposure stops the energy supply but the curing process is ongoing.

Temperature control

Compared to a standard curing cycle, the sler® technology shows a better thermal control of the curing process. This protects against interface debonding, which may lead to marginal leakage.

Shrinkage control

The sler® technology allows the dental material to relax its shrinkage stress at the end of the curing cycle. This decreases the possibility of micro-fractures both in the composite material and in the dentine substrate.

Mechanical strength increase

Composite materials cured with sler® technology show improved mechanical strength, which contributes to better clinical performances.


The operating modes are selected by pressing the „mode“ button. Depending on how long the „start“ button will be pressed for, either the short or the longcycle starts. The chosen mode is indicated by LED.
