For this post, I have put together a collection of the best light meters currently available.
Updated: May 7, 2019
Digital light meters measure the level of luminance within an area. Luminance is the the amount of light falling on a surface, defined as, "the density of the luminous flux incident on a surface".
The value is given in units of lux and/or footcandles. This convenient gadget is widely used in many areas such as construction, inspection, photography and more.
The following light meters use the latest innovative components to meet your needs and help to ensure you do your best work.
So here is my list of The 10 Best Light Meters.
1. Gossen GO Light Meter
Revamped, compact DIGISIX 2 has a weight of just 1.4oz (40g).
Expands the measuring functions of manually adjustable cameras to include incident light measurement, by means of which better exposure can be achieved for unusual subject contrast.
Integrated contrast measurement also indicates whether or not subject contrast, i.e. the difference between the brightest and darkest part of the subject, can be managed by the sensor or the film.
Comprehensive metering methods -incident and reflected light measurement.
Precision measurement and display -exposure value is ascertained and displayed in 1/3 increments.
Clear-cut display -all possible f-stop/shutter speed combinations at a glance. Timer for time exposures -timer is adjustable from 1 second to 30 minutes.
Camera bag temperature monitoring -temperature measurement and min. - max. value storage.
2. Extech LT45 Light Meter
Besides white and color LED lighting, the LT45 can measure standard light sources — fluorescent, metal halide, high pressure sodium and incandescent — up to 400,000 lux.
Display, 4,000-count, LCD, overload indication, data hold, auto power off, disable
The meter can record the maximum, minimum and average readings when changed to MAX/AVG/MIN mode.
Toggle between Lux and FC (foot-candles) units with the push of a button.
The LT45 also displays CD (luminous intensity) mode.
One-button zero calibration is quick and easy to perform.
The LT45 is auto-ranging to optimize accuracy and resolution.
Tripod mount on the bottom of the device for convenient hands-free operation.
3. Dr. Meter LX1330B Light Meter

5. Lumulabs Light Meter
Turns your phone into Lightmeter!
Modern design with two-sided use (dome and flat side)
“Volume button” works as reading trigger
Bright or dark background
Control Balance between aperture and shutter time to achieve the right effect.
Simply measure flash and control balance between flash and ambient light.
Set the correct Color temperature in any light situation. White will be White and colors will be perfect.
Use Lumu Light Meter app as a standalone spot meter, no additional hardware needed.
6. ennoLogic Light Meter
Measurement range 0-200,000 lux. Lux and Foot-Candle units.
MAX, MIN, and AVERAGE reading display and analog bar graph display.

7. Neewer Light Meter
Accuracy: ±4% ±10 digits (0-20,000 lux/2,000FC) / ±5% ±10 digits (over 20,000 lux/2,000FC).
Fast Measurement Speed (Sampling Rate): 2 times / second.
270 Degree Rotatable Detector and Built-in Calibration Filter.
Integrated optical probe rotate 270 degrees(90 Degrees to the left and 180 Degrees to the Right) which is convenient for detection of special position.
Built-in calibration filter ensures the measure accuracy of lighting in different color.
No need to adjust instrument according to different LED lighting color.
Low Power Supply and Large LCD Display: Power Supply by one 9V battery (Included) with estimated 200 hours battery life.
Low power consumption and energy saving. LCD display data hold and lower power alarm function
8. HDE DigitalLight Meter
