LUX: how much visible light reaches the point?
Measure from 2 to 180,000 lux for indoor lighting checks, workspaces, installation comparisons and other spot measurements.
AH-300 Light Meter
Brightness is only one part of the lighting story. Measure what your eyes cannot quantify.
AH-300 measures LUX and foot-candles, CCT, blue-light irradiance and blue-light percentage, provides a spectrum preview for supported white LEDs, and records multi-point LUX data for lighting-distribution checks.

Choose by the question
What can AH-300 tell you about a lighting setup?
Use each measurement for a different decision. A room can have enough average brightness and still contain dark zones, hot spots, a different color temperature, or a different blue-light component.
FC: the same illuminance in another unit.
View foot-candles when a project, specification or workflow uses FC instead of LUX. 1 FC ≈ 10.76 lux.
CCT: warm, neutral or cool white?
Use correlated color temperature to compare the apparent white-light color between fixtures, zones or lighting settings.
Blue light in W/m².
Measure the irradiance intensity of the blue-light component instead of judging it only by how blue or white the source appears.
How much of the measured white light is blue?
Use the blue-light percentage as a comparative lighting parameter. It is a measurement value, not a medical diagnosis or health verdict.
Is the whole area evenly lit?
Record multiple LUX points to reveal center-to-edge differences and compare lighting distribution instead of relying on one spot reading.
One reading can hide the real problem
Build a LUX distribution map across the area.
A center reading can look excellent while desks, shelves, work surfaces or corners receive much less light. AH-300 lets you record multiple measurement points, compare the pattern and export the recorded data.
- Record multiple LUX positions across the same room or work area.
- Review the distribution instead of relying on a single average impression.
- Export recorded LUX data as a CSV file for reports or further analysis.
Turn scattered readings into a pattern.
Use a consistent grid or repeatable set of positions to compare uniformity across a desk, room, display area or installation.
LUX or FC — same light, different units.
Use the unit that matches the project. AH-300 helps users working with both metric LUX and foot-candle specifications.
Measure without standing in the beam
Keep the sensor at the measurement point while you read from the app.
In some lighting setups, a person holding a conventional meter can shade the sensor or physically occupy the exact point being evaluated. AH-300's app-based workflow lets the meter remain at the measurement location while you view the result from outside the light path.
- Useful when body position could change the measured lighting condition.
- Helps one person perform measurements that might otherwise be awkward to read in place.
- No internet connection is required during the measurement workflow once the app is ready.
Important compatibility note
The spectrum view is for supported phosphor-converted white LEDs — not every lamp.
AH-300 can show the spectrum shape of ordinary white LEDs generated by a 450 nm blue chip exciting phosphor. This makes the function useful for comparing compatible white-LED lighting, but it should not be treated as a universal spectrometer.
Do not use the spectrum function as a general-purpose spectrum analyzer.
The current product specification says it is not suitable for white light excited by 420 nm chips, LED grow lights containing 660 nm LEDs, HPS, CMH, halogen lamps or fluorescent lamps. LUX/CCT measurement and spectrum-function compatibility are different questions.
Simple measurement workflow
Place the meter, open the app, read the result.
The app brings LUX, FC, CCT, blue-light data and compatible white-LED spectrum information into one viewing workflow.
1
Place AH-300
Put the meter at the exact work surface, desk, shelf, display or other point you want to evaluate.
2
Open the AquaHorti app
Use the app to view the measurement without needing an active internet connection during the test.
3
Compare, record or map
Use spot values for fast checks, or record multiple LUX positions when distribution matters.
Where it fits
One light meter for practical indoor and field-style lighting checks.
AH-300 is most useful when you want to quantify what a lighting setup is doing rather than judge it only by visual brightness.
Typical measurement scenarios
Use the relevant AH-300 measurement for the job: LUX/FC for illuminance, CCT for white-light color, blue-light parameters for comparison, and multi-point recording for distribution.

Artwork note:
the supplied 8085 and 8090 screenshots visibly show the label “AH-310” inside the app interface.
AH-300 is the product model on this page, so these two images are presented only as workflow illustrations.
If AH-300-labeled app screenshots become available, replacing these two images would improve model consistency.
Questions before buying
AH-300 Light Meter FAQ
Short answers to the questions that determine whether AH-300 fits your lighting workflow.
What does AH-300 measure?
AH-300 measures illuminance in LUX and foot-candles, CCT, blue-light irradiance in W/m² and blue-light percentage. It also provides a spectrum preview for supported phosphor-converted white LEDs and supports multi-point LUX recording.
What is the LUX measurement range?
The current AH-300 product specification states a range from 2 lux to 180,000 lux.
What is the difference between LUX and foot-candles?
They are two units for illuminance. One foot-candle is approximately 10.76 lux. Use whichever unit matches your project or specification.
Can AH-300 map lighting uniformity across a room?
Yes. Record multiple LUX points across a repeatable grid or set of positions, then compare the distribution. Recorded data can be exported as a CSV file.
Does the app need internet access while measuring?
No active internet connection is required during the measurement workflow once the app is ready for use.
Can AH-300 display the spectrum of any light source?
No. The spectrum function is intended for supported phosphor-converted white LEDs based on a 450 nm blue-pump chip. The current specification says the spectrum function is not suitable for 420 nm-pumped white LEDs, grow lights containing 660 nm LEDs, HPS, CMH, halogen or fluorescent lamps.
Does a blue-light percentage tell me whether a light is medically safe or healthy?
No. AH-300 reports blue-light measurement parameters. Those values can be used to compare lighting conditions, but the meter should not be used by itself to make a medical diagnosis or a health-safety determination.
