2 best c e light meters

CE light meters are instruments used for measuring the intensity or illuminance of light in a given area. They are commonly used in various fields, including photography, film production, architecture, interior design, and environmental monitoring. Here are some key points about CE light meters:

  1. Purpose: CE light meters are designed to measure the level of visible light in lux or foot-candles. They provide accurate readings of how bright a particular space or object is, helping professionals make informed decisions regarding lighting.

  2. Measurement Units: Light meters can display readings in different units, such as lux (metric) or foot-candles (imperial). The choice of unit depends on the user's preference and the industry standards in their field.

  3. Types: There are various types of CE light meters available, including digital and analog models. Digital light meters typically provide precise readings and may have additional features like data logging and data transfer capabilities. Analog light meters use a needle or dial to display measurements and are often simpler to use.

  4. Applications:

    • Photography: Photographers use light meters to measure ambient light and adjust camera settings, such as aperture and shutter speed, for optimal exposure.
    • Film Production: Cinematographers use light meters to ensure consistent lighting levels on film sets, helping maintain visual consistency in scenes.
    • Architecture and Interior Design: Professionals in these fields use light meters to assess natural and artificial lighting in spaces to create functional and aesthetically pleasing environments.
    • Environmental Monitoring: Researchers and scientists use light meters to study natural light conditions in various ecosystems, which can be crucial for understanding plant growth and animal behavior.

  5. Calibration: CE light meters should be periodically calibrated to maintain accuracy. Calibration ensures that the readings provided by the meter are reliable and consistent over time.

  6. Features: Some modern CE light meters come with additional features, such as data storage, data analysis, and the ability to measure color temperature or spectral distribution of light.

  7. Portability: Light meters are often designed to be portable and easy to carry, making them convenient for on-site measurements.

  8. Cost: The price of CE light meters can vary significantly depending on their features and precision. Entry-level models may be more affordable, while professional-grade meters with advanced capabilities can be more expensive.

When selecting a CE light meter, it's essential to consider the specific requirements of your application, including the desired measurement range, accuracy, and any additional features needed for your work.Additionally, ensure that the meter meets any industry or regulatory standards relevant to your field of use.

User questions & answers

Question: How do you measure monocular near pd at 40 cm
Answer: It is directly converted by the button, that is, the interpupillary distance is measured as before, and then press the PD button, it will display the data of 30CM, and press it again to get the data of 40CM
Question: What's the difference between ly-9c and ly-9at
Answer: For these two models, we more recommend LY-9AT. The first is the difference in appearance. Secondly, LY-9C is an automatic switch machine, LY-9AT is a button operation model. At last, in terms of accuracy, the LY-9C is 0.5mm per shift, and the LY-9AT is 0.5m or 0.1mm adjustable. If you need to measure monocular pupil distance, LY-9AT will be more suitable than LY-9C.
Question: What kind of outlet or adapter does this require for the US? What kind of plug is it
Answer: Hello, the power adapter and plug are suitable for the United States, 110V, two-end plug, you can use it directly in the United States after purchase.
Question: Where is this made
Answer: Made in China.

Brief Introduction of Pupil Distance Meter and Pupil Distance

PD Meter: a precision optical instrument used to measure distance between human pupils in the process of optometry for fitting spectacles.

Pupil Distance:

◆Binocular Pupil Distance VS Monocular Pupil Distance

Binocular PD: the distance from the center of the pupil of the two eyes.

Monocular PD: the distance from the center of the pupil of the right or left eye to the nasal centreline.

One-eyed, squinted, especially those who need progressive multifocal lenses, need to measure their monocular pupil distance.

◆Distant Pupil Distance VS Near Pupil Distance

Distant PD: the distance between the pupil centers of two eyes when they are looking at the infinite distance.

Near PD(NCD): the distance between the pupil centers when gazing at a near target, that is, when reading at 30-40 cm or working at close distance.

Near pupil distance is always smaller than distant pupil distance.

Sight Distance Can be Set to 30/40/50/100/200cm
