IP Ratings

Often when looking at various LED products, you will see will usually see references made to IP ratings.

All items can be classed with an IP rating. Quite simply, the first numeral denotes the level of protection against dust/solids, and the second number denotes the level of protection against liquids. For interior use, generally IP20 is sufficient assuming it is in a dry area with little to no serious humidity. Garden lighting for example bollards and bricklights generally need at minimum a rating of IP33. If you're not sure, please feel free to email us do discuss your needs. 

1st numeral:

  1. Protection against solid object larger than 50mm,
  2. Objects larger than 12mm.
  3. Objects larger than 2.5mm.
  4. Objects larger than 1mm.
  5. Protection against dust but not entirely prevented. 
  6. No ingress of dust.

2nd numeral:

  1. Protection of dropping water.
  2. Drops of water when the object is tilted by 15 deg from normal position
  3. Spraying water at up to 60 deg from vertical.
  4. Splashing and spraying water from any direction.
  5. Water jet from any direction at low pressure.
  6. Strong water jet from any direction.

  8. Water immersed to a specified depth.
