Ambient lighting – Just the name given to the general lighting in the area, this can also refer to the amount of daylight in the room. Usually, you consider the ambient lighting and build up the other parts of lighting around this.
Daylight harvesting – When a lighting design uses the natural daylight as part of the design. This can really reduce energy consumption Floodlight – Used to light up an object or scene so that it’s much brighter than its surroundings.
Maintained lighting – Lighting that is designed to be continuously lit, even in the event of power failure. So, emergency lighting – which can be used for multiple different things.
Non-maintained lighting – These won’t stay on during a power-cut, basically the opposite to maintained lighting.

DALI – Stands for Digitally Addressable Lighting Interface. This is a digital system that allows you to control your lighting from a computer. Used in commercial settings quite often.
Dimmable – Some lamps allow the Lumens to be increased and decreased. This is a great way to reduce energy consumption. IK – Stands for Impact Protection, this measures the degree of protection that your electrical equipment. The higher the rating the better.
UGR – Means Unified Glare Rating and it measures the glare (the visual discomfort you feel when confronted with excessive brightness). The lower the rating of the UGR, the better. The higher the rating, the more likely you are to notice a visible distraction.
PIR – A Passive Infrared Sensor. You know those garden lights which turn on when somebody walks nearby? This is what does that. It radiates wavelengths, and when it detects heat energy or movement, it is triggered and turns up. Perfect for security measures.
Watt – A watt is a unit of electrical power. Basically, they represent the rate at which they consume the energy.
Lumen – Used to describe just how much illumination your bulb will provide you with.
Lux – Used to describe the intensity of the light being emitted. This differs from Lumen as it takes into consideration the area that it reaches.
