Compares the property being valued with similar properties that have recently sold in the same area.

Material with electrical conductivity between a conductor and an insulator. Conductivity can be modified by adding impurities to crystal structure.

Flickering that occurs in lighting environments that are not regulated correctly. The strobe effect represents an unwanted periodic or non periodic change of light and its effect on visual perception.

Economic principle affecting real estate value based on the availability of properties and the demand for them.

LED chip utilizing surface mount technology. Electron hole components are mounted directly onto the board surface, enabling smaller structure and better heat dissipation. Without relying on an epoxy covering, SMDs can achieve a broader beam angle. Lower energy flow leads to reduced energy and longer technological lifetime.

Instrument designed to protect electrical equipment from power surges by redirecting excess voltage.

Lighting designed to provide focused light for specific tasks (e.g., reading, cooking).

Legal term that refers to the ownership rights in a property.

Numeric representation of distortion in the current waveform relative to the sinusoidal voltage waveform on the AC main. Harmonics are unwanted currents at multiples of the fundamental line frequency that create power losses, as awell as a buzzing sound.
