The HTC LX-108L Digital LED Lux Meter is a professional-grade handheld light intensity measurement device designed for engineers, lighting technicians, photographers, and facility managers who demand accuracy and versatility. Engineered by Hazari Tech Connect (HTC), this instrument delivers precise illuminance readings across an exceptionally wide range from dim ambient lighting to ultra-bright industrial environments.

Equipped with a highly responsive silicon photodiode sensor and a large, easy-to-read digital display with backlight, the LX-108L ensures reliable performance even in challenging lighting conditions. The device supports dual unit measurement in both Lux (lx) and Foot-Candles (fc), making it suitable for international standards compliance and diverse professional applications.

What sets the LX-108L apart is its Self-Defined Light Source calibration feature, allowing users to select from six predefined light source profiles—including White LED, Natural Daylight, Tungsten, Fluorescent, Metal Halide, and High Pressure Sodium—to ensure measurement accuracy tailored to the specific light source being evaluated. The 180-degree rotating sensor head further enhances usability by enabling easy positioning for overhead, wall-mounted, or ground-level measurements.

With intelligent functions such as Data Hold, Max/Min/Average recording, Over-Range indication, Low Battery alert, and Auto Power-Off, the LX-108L combines robust functionality with user-friendly operation in a durable, ergonomic housing built for field use.

Frequently Asked Questions - HTC LX-108L Digital LED Lux Meter

Q1: What is the difference between Lux and Foot-Candle, and when should I use each?

Lux (lx) and Foot-Candle (fc) are both units of illuminance. Lux is the SI metric unit (1 lux = 1 lumen per square meter), while Foot-Candle is the imperial unit (1 fc = 1 lumen per square foot). Use Lux for international standards, European projects, and scientific work. Use Foot-Candles for North American building codes, theatrical lighting, and photography applications in the United States. The LX-108L allows instant switching between both.

Q2: How do I use the Self-Defined Light Source feature?

Press the Light Source (L.S.) button to cycle through the six preset profiles: L1 (White LED), L2 (Natural Daylight), L3 (Tungsten), L4 (Fluorescent), L5 (Metal Halide), and L6 (High Pressure Sodium). Select the profile that matches the dominant light source in your environment. This applies a spectral correction factor to ensure your reading reflects the true illuminance for that specific source type.

Q3: Why does my reading show ''OL'' on the display?

''OL'' stands for Over-Load or Over-Range. It appears when the light intensity exceeds the maximum measurable limit of the current range (200,000 Lux / 20,000 fc). If you see ''OL,'' the light source is too bright for the meter to measure. Move farther from the source or use a neutral density filter if applicable. Never expose the sensor to direct sunlight or laser sources.

Q4: Can I measure LED lighting accurately with this meter?

Yes. The LX-108L is specifically designed as a Digital LED Lux Meter. By selecting the L1 (White LED) light source profile, the meter compensates for the unique spectral output of LED lighting, providing more accurate readings than standard lux meters that are calibrated only for incandescent or daylight sources.

Q5: How does the 180° rotating sensor head help?

The rotating sensor allows you to position the light-collecting dome at the optimal angle without twisting your wrist or body. This is especially useful when measuring ceiling lights, wall-mounted fixtures, or when placing the meter on a flat surface. It ensures the sensor faces the light source directly for the most accurate cosine-corrected reading.

Q6: What does the Data Hold function do?

Data Hold freezes the current measurement value on the LCD screen. This is useful when you need to take a reading in an awkward position (such as overhead) and then bring the meter down to eye level to record the value. Press the HOLD button to freeze; press again to resume live measurement.

Q7: How do I view the Max, Min, and Average values?

Use the REC (Record) and related function buttons to enter the statistical mode. The meter will track the highest (Max), lowest (Min), and calculated average reading over your measurement session. This is valuable for assessing light uniformity in offices, studios, or production floors where consistent illumination is critical.

Q8: Does the meter come with a backlight for dark areas?

Yes. The LX-108L features a built-in display backlight that illuminates the LCD screen, making it easy to read measurements in dark environments such as theaters, tunnels, unlit warehouses, or nighttime outdoor inspections.

Q9: What type of batteries does the LX-108L use?

The LX-108L is battery-operated. Please refer to the user manual included in the package for the exact battery type and quantity required (typically a 9V battery or AA batteries). The device includes a low-battery indicator on the display to alert you before power runs out.

Q10: Is this lux meter suitable for professional certification and compliance audits?

Yes. With its high accuracy of ±(3% + 3 Lux), cosine correction, source-specific calibration profiles, and wide dynamic range, the LX-108L is well-suited for workplace lighting audits, OSHA compliance checks, photography studio setup, greenhouse lighting assessment, and LED installation verification.
