What is light?

Light intensity is the measurement of how much visible light is present in a space, showing how bright or dark the environment is at any given time. Indoor light levels are affected by daylight from windows, artificial lighting and the time of day, and they can vary greatly between rooms. Tracking light over time reveals patterns, such as lights being left on at night or in empty rooms. Measuring light helps building, workplace and facility teams ensure spaces have the right lighting and identify where energy is being wasted.

● THE WHY 

Why does light matter?

Light isn't just about seeing clearly. It affects occupant comfort and performance, and lighting is one of the largest consumers of electricity in commercial buildings.

Light 1

Cut lighting costs


Lighting is a significant source of electricity use in commercial buildings. Light data shows when lights are left on overnight or in unused spaces, helping you reduce unnecessary energy use, lower costs and support your sustainability goals.
Co2 1

Support comfort and focus


Poor lighting can cause eye strain, fatigue and headaches, making it harder for employees and students to concentrate. Monitoring light levels helps you ensure offices and classrooms have the right conditions for people to feel well and perform their best.
Light 3

Verify lighting systems


Automatic lighting and timers don't always work as intended. Remote light monitoring lets you check that systems switch off when they should, across all your buildings, without having to be on site.

Light over time

Track light levels across rooms and buildings in real time. See when lights are on or off, spot spaces that stay lit after hours and follow patterns over time, so your team can cut energy waste and keep spaces comfortable for the people using them.
