Advantages of 4XLED lamps: TOUGH, DURABLE CONSTRUCTION Precision milled housing, made of high strength aluminium 2017A alloy, so called duraluminium. Nevertheless, the lamps are by far much lighter and smaller than other products with similar light power. WATERPROOF HOUSING Very effective sealing, IP68 or IP69K grade, both sides of the glass are sealed, the lamp is equipped with a scrued front bezel (NOT an adhesive bonded front glass).

BEST QUALITY LENSES Best available lenses, selected for maximum illumination of the field of view. We are using no cheap lenses integrated in front glass, giving 10% less efficiency. HIGH PERFORMANCE ELECTRONICS High performance electronics, the real efficiency of our integrated in the lamp power converters is 98%. Therefore, our lamps need 10-20% less electrical power than most other products. SHOCK SECURED The electronics is completely sealed and shock secured by special polymer filling of the housing. DURABLE CABLE The electrical supply is carried out with a halogen free, frost proof, durable cable, terminated with well proven water tight Superseal connectors.ts is placed in Poland.
