Protection against dust, solid objects and moisture
The waterproof light fixtures made by IBV Hungária Kft. have very high (IP 65) protection against dust and water, and accordingly, can be used very effectively, where protection against dust, vapour, humidity and soiling is necessary. In case of outdoor application the protection of the luminaire by a protecting roof is recommended. On customer’s request IP 67 protection grade is available.
The luminaires must be resistant to moisture and dust on a level defined in the standard for luminaires.
In case of the lowest level the luminaires are not protected against moisture and dust, but the parts under voltage can only be reached using tools.The luminaires without given grade of protection have IP 20 protection.
