Characteristic code281Products with IP codes are designed to provide the necessary level of ingress protection for their intended applications based on the system of protective ratings defined by the IEC （International Electrotechnical Commission）.These protection ratings, which are included in product specifications as appropriate, are indicated by a two-digit code as shown to the right （and as defined by IEC 529）.IP 00The 2nd characteristic （0 to 8）: Liquid ingress protectionThe 1st characteristic （0 to 6）: Solid particle protection（protection against nearby or external solid particles） due to variations in element quality.specification may differ.stated in the catalogue are reference values and are not guaranteed values. Please consider them as a guide.● Thermal insulation unavailable. ● LED of all products are non-replaceable.● Some of the images and data on each page represent colors and brightness that are simulated for explanatory purposes. Actual product ● Numerical values such as luminous flux value, light distribution, color temperature, illuminance distribution, power consumption etc. No protectionThe device is protected against external solid particles or objects with a diameter of 50 mm or greater. This level of protection is sufficient to keep an adult’s clenched fist away from hazardous locations.The device is protected against external solid particles or objects with a diameter of 12.5 mm or greater. This level of protection is sufficient to keep an adult’s fingers away from hazardous locations.The device is protected against external solid particles or objects with a diameter of 2.5 mm or greater. This level of protection is sufficient to keep tools away from hazardous locations.The device is protected against external solid particles or objects with a diameter of 1.0 mm or greater. This level of protection is sufficient to keep wires away from hazardous locations. The device is protected such that ingress of dust resistance test particles （with a diameter of 75 μm） will not compromise its operation or safety. The device is protected against ingress of dust resistance particles （with a diameter of 75 μm）. Rating indicating level of protection against ingress of water from outside the product with harmful effectsNo protectionWater dripping onto the product from above has no harmful effect.Vertically dripping water has no harmful effect when the enclosure is tilted in either direction at an angle of up to 15°.Water falling as a spray at any angle up to 60° from the vertical has no harmful effect.Water splashing against the enclosure from any direction has no harmful effect.Water projected by a nozzle against the enclosure from any direction has no harmful effect.Water projected in powerful jets against the enclosure from any direction has no harmful effect.Ingress of water sufficient to produce a harmful effect does not occur when the enclosure is immersed in water under defined conditions of pressure and time.Ingress of water sufficient to produce a harmful effect does not occur when the enclosure is continuously immersed in water under manufacturer-defined conditions that are more rigorous than those described in No. 7 above.The 1st characteristic numeral （solid particle protection）NumeralRating indicating level of protection against nearby or external solid particles from outside the product0123456The 2nd characteristic numeral （Liquid ingress protection）Numeral012345678Protection ratings （IP codes）Notice● Please note that the specifications described in this catalogue are subject to change without notice.● Unlike conventional light sources such as incandescent lamps and fluorescent lamps, LED lights can differ in terms of color and brightness
