Ceiling light is a lighting fixture with reflector tightly fixed to the fixing surface – usually ceiling or wall.
Microwave sensor is motion detector, which emits microwave signals and measures the time taken for the signal to be reflected back to the sensor, this is known as the echo time. The echo time is used to calculate the distances from all the stationary objects in the detection zone, to establish a baseline to work from. A person moving into the detection zone causes a disruption in the microwave beam, changing the echo time and triggering the lights.

What do the two digits in an IP Rating mean?
IP rating is also known as Ingress Protection or International Protection ratings which are defined to the international standard of EN 60529 (British BS EN 60529:1992). This standard is used to define the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies such as tools, dirt and moisture.
The rating consists of the letters IP followed by two digits, if a number is replaced by X this indicates that the enclosure is not rated for that specification.
IP65 = First Digit - Solids
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (electrical conductors, moving parts etc) and the ingress of solid foreign objects.
IP65 = Second Digit - Liquids
The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc).
| Digit | Intrusion Protection | Second Digit | Moisture Protection |
| 0 | No protection. | 0 | No protection. |
| 1 | Protected against solid objects over 50mm, e.g. accidental touch by hands. | 1 | Protected against vertically falling drops of water, e.g. condensation. |
| 2 | Protected against solid objects over 12mm, e.g. fingers. | 2 | Protected against direct sprays of water up to 150 from the vertical. |
| 3 | Protected against solid objects over 2.5mm, e.g. tools & wires. | 3 | Protected against direct sprays of water up to 600 from the vertical. |
| 4 | Protected against solid objects over 1mm, e.g. wires & nails. | 4 | Protected against water splashed from all directions, limited ingress permitted. |
| 5 | Protected against dust limited ingress, no harmful deposits. | 5 | Protected against low pressure jets of water from all directions, limited ingress permitted. |
| 6 | Totally protected against dust. | 6 | Protected against strong jets of water, e.g. on ships deck, limited ingress permitted. |
| 7 | Protected against immersion, up to 1 meter in depth. | ||
| 8 | Protected against immersion, up to 3 meter in depth. | ||
| 9 | Protected against powerful high-temperature water jets |
