Explanation of symbols

At Mullan Lighting we're proud of the accreditations we have earned to ensure our products are not only manufactured to the highest standards, but are sustainable produced, limiting our impact on the environment around us. Below is a short explanation of some of the symbols and quality assurance marks found on our website.

  • CE mark
    CE mark: The CE mark is a mandatory conformity marking for certain products - including light fixtures - sold within the European Economic Area (EEA) and indicates the compliance with EU legislation of a product. It's also found on products that are manufactured in the EEA but sold outside the EEA and is therefore an internationally recognisable symbol of compliance to EU legislation regarding product safety, health, quality and environmental protection. It is similar to the FCC Declaration of Conformity used on certain electronic goods sold in the United States.
  • UL listed
    UL listed: The UL symbol means the product, after a series of testing, meets the UL nationally recognized Standards of Safety. UL is an American non-profit organization dedicated to public safety and Mullan Lighting is proud to have the majority of its products UL listed.
  • IP rated
    Waterproof symbol: This water droplets symbols indicates that the product is moisture-resistant and suitable for use in bathrooms and outdoors. The product has a minimum IP rating of IP44 (most are IP54), meaning it is protected from water spray from any direction.
  • Class II symbol
    Class II: A Class II (Class 2) or double insulated electrical appliance (light fixture) is one which has been designed in such a way that it does NOT require a safety connection to electrical earth (ground). An added layer of safety against electrical shock is acheived by using double layers of insulating material or reinforced insulation protecting any live parts of the fitting.

What does IP rating mean?

IP rating is a two-digit number used to provide an Ingress Protection rating to electronic products (like our light fixtures). The first digit represents protection against ingress of solid objects while the second digit represents protection against ingress of liquids (water). The larger the value of each digit, the greater the protection. For example, a product rated IP54 (like our outdoor lights) is better protected against environmental factors than a product rated IP20 (like most of our indoor pendant lights).

IPFirst digit:
Ingress of solid objects
Second digit:
Ingress of liquids
0 No protection No protection
1 Protected against solid objects over 50mm e.g. hands, large tools. Protected against vertically falling drops of water or condensation.
2 Protected against solid objects over 12.5mm e.g. hands, large tools. Protected against falling drops of water, if the case is disposed up to 15 from vertical.
3 Protected against solid objects over 2.5mm e.g. wire, small tools. Protected against sprays of water from any direction, even if the case is disposed up to 60from vertical.
4 Protected against solid objects over 1.0mm e.g. wires. Protected against splash water from any direction.
5 Limited protection against dust ingress.
(no harmful deposit)
Protected against low pressure water jets from any direction. Limited ingress permitted.
6 Totally protected against dust ingress. Protected against high pressure water jets from any direction. Limited ingress permitted.
7   Protected against short periods of immersion in water.
8   Protected against long, durable periods of immersion in water.

Bathroom lighting safety zones

There are four zones to be considered when designing or installing bathroom lighting.

IP rating safe zones for bathroom lighting

Zone 0; inside the bath or shower itself. Any fitting used in this zone must be "SELV Safety Extra Low Voltage" and be rated at least IP67, meaning it is immersion proof.

Zone 1; the area above the bath to a height of 2.25 metres from the floor. In this zone a minimum rating of IP44 is required. If the fitting is 240V a 30ma Residual Current Device (RCD) must also be used to protect the circuit in this zone.

Zone 2; the area stretching 600mm outside the perimeter of the bath end and to a height of 2.25 metres from the floor. In this zone an IP rating of at least IP44 is required. Also in addition, it is good practice to consider the area around the wash basin within a 600mm radius of any tap to be considered as zone 2.

Zone 3; anywhere outside zones 0, 1 or 2 (subject to specific limits) and where no water jet is likely to be used. No specific IP rating is required.

In addition to the above information, if there is a likelihood of water jets being used for cleaning purposes in zones 1, 2 or 3, a fitting rated a minimum IP65 must be used.
