In Singapore's demanding climate, where humidity is high and heavy rains are the norm, understanding IP ratings for your commercial and industrial lighting is important as it will impact safety, longevity, and cost-effectiveness of your lighting. That's why we have prepared this comprehensive guide to help you make an informed decision on your lighting.
What Does IP Stand For and Why It Matters for Singapore:
IP stands for "Ingress Protection." This international standard (IEC 60529) clearly defines a luminaire's resistance to solid objects and liquids. For Singapore, this is particularly important as the consistent high humidity can lead to corrosion in inadequately protected fixtures, while sudden heavy rainfall demands robust water resistance for outdoor installations. Understanding IP ratings prevents premature failure, ensures electrical safety in compliance with Singaporean standards, and ultimately saves you money on replacements and maintenance.
Decoding the Two Digits:
An IP rating always consists of two numbers:
The First Digit (Protection against Solids): This number indicates the level of protection against the ingress of solid foreign objects, ranging from accidental touch to dust.
IP Rating | Description |
| No protection against solid objects. |
| Protected against solid objects greater than 50mm (e.g., accidental touch by hands). |
| Protected against solid objects greater than 12.5mm (e.g., fingers). |
| Protected against solid objects greater than 2.5mm (e.g., tools and thick wires). |
| Protected against solid objects greater than 1mm (e.g., thin wires and small tools). |
| Dust-protected – ingress of dust is not entirely prevented, but dust must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment. |
| : Dust-tight – no ingress of dust. |
The Second Digit (Protection against Liquids): This number indicates the level of protection against the ingress of liquids, ranging from dripping water to high-pressure water jets. This is particularly relevant in Singapore's humid environment and potential for heavy rainfall.
IP Rating | Description |
| No protection against liquids. |
| Protected against vertically falling water drops. |
| Protected against vertically falling water drops when the enclosure is tilted at an angle of 15 degrees from its normal position. |
| Protected against spraying water at an angle of up to 60 degrees from the vertical. |
| Protected against splashing water from any direction. |
| Protected against water jets projected by a nozzle from any direction. |
| Protected against powerful water jets projected by a nozzle from any direction. |
| Protected against the effects of temporary immersion in water (up to 1 meter). |
| Protected against the effects of continuous immersion in water under conditions specified by the manufacturer (usually greater than 1 meter). |
| Protected against powerful high-temperature water jets. (Less common in general lighting but important in specific industrial applications). |
Choosing the Right IP Rating for Your Singapore Space
Selecting the appropriate IP rating is paramount for the longevity and safety of your lighting in Singapore's specific conditions. Here's a localized guide:
Indoor, Dry Areas (e.g., Offices, Retail Spaces, Homes): Generally, IP20 suffices. Warehouses in industrial areas like Jurong should aim for IP50 or higher to combat dust.
Bathrooms and Kitchens: Minimum IP54 for splash protection. Areas with direct shower spray require IP65 or higher to withstand water jets.
Outdoor Areas (Gardens, Walkways in Singaporean MCST condominiums or commercial properties): A minimum of IP65 is strongly recommended to handle dust and Singapore's tropical downpours.
Industrial Environments (Factories, Workshops across Singapore): Depending on the specific industrial process (e.g., food processing with washdowns), ratings from IP54 to IP65 or higher are often necessary.
Near Swimming Pools or Fountains (common in Singaporean recreational facilities): IP67 or IP68 are essential for submerged or frequently splashed fixtures to ensure safety and prevent electrical hazards in accordance with regulations.
