Body and locking flange made of AISI 316L stainless steel with electropolishing treatment. External power supply with a constant current transformer from 350mA to 700mA, to be wired in series. IP68 protection with Full Dry system which avoids condensation inside the product. Before fixing the diffuser on the Platek products a Pre-treatment using an atmospheric pressure plasma process is carried out on the surface. The process activates the ionic load on the surface exactly where it is needed, thus promoting the best silicone grip possible and removing any residual release of agents for a longer lasting seal. The next steps are the coating of silicone and the assembly of the diffuser on the lighting fixture, with an automated process to guarantee the perfect sealing of the lamp.
