LED Lux Meter ( HTC – LX-108L )

Description

HTC LX‑108L Digital LED Lux Meter – Advanced Illumination Measurement for LED and Lighting Professionals

The HTC LX‑108L is a precision lux meter specifically designed for LED and light-source performance testing. Engineered for professionals in lighting design, photography, horticulture, occupational safety, and industrial quality control, this handheld meter delivers accurate light intensity measurements with a clear bar‑graph display and flexible measurement modes. Compact, intuitive, and dependable, it enables users to evaluate brightness levels quickly and reliably in demanding environments.

Precision Measurement for LED and Light Sources

The HTC LX‑108L provides accurate illumination readings within a practical range—up to 200,000 lux or 20,000 foot-candles—making it well suited for typical to high-intensity lighting environments. Its photodiode sensor, optimized for the spectral response of LED sources, ensures enhanced accuracy when measuring modern lighting systems. With accuracy specified as ±(3% + 5 lux) under standard incandescent calibration and similarly tight performance across LED-based lighting, this meter supports exacting measurement requirements.

Broad Range and Responsive Display

The meter can auto-range automatically across three lux intervals—1,000; 10,000; and 200,000—along with corresponding foot‑candle scales of 100, 1,000, and 20,000. The high-resolution LCD display includes a dynamic bar‑graph indicator that gives visual context for light level trends and changes. With a sampling rate of approximately two measurements per second, users receive real-time feedback suitable for fast-paced lighting inspections.

Versatile Measurement Modes

Equipped with functions such as data-hold, relative value measurement, and MAX/MIN/AVERAGE tracking, the LX‑108L adapts to varying testing scenarios. The data-hold feature captures a specific reading for documentation. MAX and MIN modes allow capturing high and low values during a session, while AVERAGE provides an overall assessment of light level stability. The relative mode displays differences from a baseline measurement, helpful for comparative inspection tasks across lighting zones.

Rotatable Probe & Light Source Calibration

The meter includes an innovative 180° pivoting probe, enabling easy orientation and placement in tight or awkward positions, improving usability during ceiling inspections or angled light assessments. Further enhancing precision under LED lighting conditions, the LX‑108L allows self-defining light source coefficients, enabling calibration adjustments for specific LED types such as red, blue, green, yellow, and purple lighting.

Auto‑Power-Off & Battery Efficiency

Powered by three AAA batteries, the unit delivers long operational life and includes low battery indication for preventive replacement. With an auto-shutdown feature activated after ten minutes of inactivity, it conserves energy during idle periods, making it ideal for extended field inspections or audit schedules

Ergonomic Design and Portability

Weighing approximately 140 grams and designed with compact dimensions under 20 cm in length, the LX‑108L is lightweight and handy for field work. Its portable build is paired with a durable casing that protects internal electronics from wear and light-duty impacts. The instrument is convenient to carry during lighting surveys, site audits, or inspections across multiple locations
