RATINGS
The IP (International Protection) rating given to a piece of electrical apparatus is a two digit code
indicating the degree of protection its enclosure affords it. The first digit represents protection
against penetration by solid objects accessing hazardous parts, the second describing the
enclosures, protection against the ingress of water. An X in place of either digit means that
either the enclosure has not been tested or that the test is not applicable.
NOTE:
In the event of additional holes being drilled, pierced or knockouts removed, suitable measures should be taken to
restore the product to its original rating IEC 529, BS EN 60529 does not apply tp protection against the risk of explosion or
conditions such as humidity, corrosive gases, fungi or vermin. In certain cases equipment designed to be mounted in an
enclosure will contribute towards the stated IP rating, (e.g. pushbuttons mounted in an enclosure). Different parts of
enclosures can have different degrees of protection and still conform to the standard.

Lumens, the latest unit of measurement for Lamps
Purchasing the correct lamp can be a confusing task. For many years, lamps have been purchased according to wattage. But as
technology advances, low-wattage, energy efficient lamps have become readily available at an affordable price.
Now, instead of focusing on wattage, a measure of power or energy used, the vast majority of manufacturers are turning to
lumens for their energy efficient lamps.
While this may confuse the market initially, it’s actually a more accurate measurement of how bright the light will be.
The simple table below compares brightness to the traditional wattage for standard, halogen, CFL and LED lamps, and enables the
user to choose the correct lamp for lighting the space as required.

Converting Lumens to Watts
Measuring and labelling light output instead of energy use makes it easier for you to find the right energy efficient lamp for your
space. Use this chart to determine how many lumens you'll need from your next lamp. For example, if you typically purchase 60W
incandescent lamps, which produce about 700-800 lumens, consider purchasing a lower energy alternative like a 42W halogen
lamp, 12W CFL, or even a 10W LED lamp to achieve the same brightness.
Shop for the right lamp for your space using the chart below.
