The Extech HD450 Datalogging Light Meter is a professional illuminance meter designed for UK electricians and lighting technicians who need accurate light level measurements for installation checks, workplace assessments and maintenance tasks. It measures light intensity in foot-candles (Fc) and lux, covering everything from low-level ambient lighting to high-output commercial and industrial installations.
With high resolution, fast peak capture and onboard data logging, the HD450 supports both spot measurements and longer monitoring sessions. It’s well suited to lighting inspections in offices, schools, warehouses, retail spaces and industrial environments.
How does the Extech HD450 support everyday lighting work?
The HD450 combines fast response with practical recording features, allowing electricians to capture peak light levels, compare changes using relative mode and store results for reporting. Its remote light sensor and clear backlit display make it easy to use in ceiling spaces, plant rooms and low-light areas.
