Firstly, the installation of any lighting control within an application can provide significant benefits, not only in energy saving, but also in the continued specified performance and the economic life of the lighting fittings.

There are three basic types of control to consider.

Photo Electric Cell Units are basically a switch which operates automatically based upon the amount of ambient light and their function is in two different operations, to switch the lighting on when the ambient lighting level falls below a given value and to switch the lighting off when the ambient lighting level rises above the given value.

Microwave sensors operate by emitting a high frequency microwave beam over a designated area and when that beam is invaded by motion, this determines presence and activates the lighting to be switched on. An ideal solution for external lighting applications as they do not require a hole to be cut into the luminaire.

Passive Infra-Red Sensors (PIR) are electronic sensors which measure Infra-red light radiating from objects within the field of view, working where infra-red radiation enters the segmented front.

All electrical devices are tested to determine a level of resistance against the intrusion of solids and liquids.

Once tested, the product is given an IP rating, which stands for Ingress Protection. IP Rating uses a two-digit code where the first digit is a number value of between 0 & 6, for protection against ingress from a solid object, and the second digit is a number value of between 0 & 9, for resistance against ingress of moisture.

Ingress protection is important as it allows the safe use of lighting equipment within environments where it is possible dust particles and water may get into the fitting and having a suitable IP Rating will give customer confidence in purchasing lighting fittings which are suited to the application into which they are to be installed.

All light sources degrade over time. LM80 is the method for measuring how much lumen depreciation the light source will suffer. This is not to be confused with an estimation of life. LED's typically do not fail as they have no filament to burn to end their life, rather degrade beyond useful life output.
