The purpose of the current study was to evaluate the performance of two laboratory light polymerization systems used to polymerize an indirect composite (Sinfony). A two-step polymerization system (Visio-Alfa and Beta) and a halogen-metal halide unit (Twinkle MIII) were assessed. The composite was polymerized either with the Visio units or with the MIII unit for different exposure periods. Knoop hardness, water sorption, and solubility in water of the composite polymerized with the following modes were determined: Visio, 15 minutes; MIII, 30, 60, 90, 120, and 180 seconds. Extension of light exposure time to the MIII unit improved the hardness of the composite from 30.5 (30s) to 40.7 (180s), whereas hardness obtained with the Visio units resulted in 24.8 (15 minutes). Water sorption and solubility of the composite were greater when it was polymerized with the Visio units than with the MIII unit.
