All About Light Bulb IP Ratings

High Ratings 

Higher IP ratings are best for areas that wil be exposed to debris and water or weather conditions, such as industrial ,factory and unprotected outdoor lighting. If yu know there is potential for contact with dust or liquids , make sure that yu select a high IP rating to ensure your light bulbs have eadequate protection. 

IP ratings of 65 and above are considered to be weatherproof and are suitable for both indoor and outdoor use, with some small but important variations between the numbers:
