Best PAR Light Meter Reviews For LED Grow Lights

People often assume that the growth of plants can be boosted by exposing them to bright light. However, most of the time, this action does more harm than good because light brightness is not the only determining factor in a plant’s growth. The color of the light matters a lot too, and the PAR light meter is the perfect equipment to help you in this regard.

Plants do not make use of all the light they are exposed to. They reflect a significant part of the entire light spectrum back and utilize only the Photosynthesis Active Radiations (PAR). According to the light spectrum, the wavelength of PAR ranges between 400-700nm. A PAR Light Meter, as the name indicates, helps determine whether the PAR range of the light is beneficial for the plants or not.

This makes buying a PAR light meter an excellent investment that can help you determine if the LED light your plants are exposed is good enough. Here are the reviews of some of the best LED PAR meters for grow lights:

PAR Light Meter Reviews 2020:

#1

1) Sun System PAR With Remote Sensor

The Sun System PAR Remote Sensor can measure the PAR intensity for both growths as well as natural light. Both integrated and remote sensor options are available for this device. The small size of the meter makes it very convenient for regular use.

Buttons on the PAR light meter sensor enhance the usability of the product and also allow the user to choose between the automatic and manual operation. Each mode is capable of taking up to ninety-nine readings and displaying their spatial average.

A one year warranty is also offered with the product along with a detailed user manual that helps one understand how to use the meter properly. The 300 dollars price tag surely makes it expensive, especially considering the fact that it is not waterproof.

2) Light Meter LM-50KL

The Light Meter LM-50KL can be used to measure the intensity of light for LED grow lights as well as other types of visible light sources. The device is very simple and basic in terms of design. It comes with only five buttons and weighs merely 14.1 ounces. Dimensions of the product are 9.3×5.1×2.9 inches.

The units for measuring light in the product are lux and foot-candles. One foot candle is equal to the brightness of one-candela light source that is placed at a distance of one foot from the point of measurement.

The use of this device is not restricted to measuring the PAR light intensity for plants. It is a versatile product that can also be used in warehouses, factories, and houses. It is highly affordable and is a great option for anyone looking for a cheap yet efficient light meter. There is no compromise on the quality of the product despite the cheaper price.

3) URCERI Handheld Digital LightMeter Ambient Temperature Measurer

The URCERI Handheld Digital LightMeter Ambient Temperature Measurer is the first choice when one has accuracy as the top priority. The recording rage for the temperature sensor lies between 0 – 200,000 lux. This is one of the best PAR light meters that are affordable as well as accurate in terms of the quality of the measurement.

This meter is very basic. There is an LCD on the meter that indicates the measured reading, along with the maximum and minimum values. Other information like the battery percentage is also visible on the LCD. Other than that, a mention-worthy feature is the automatic power-off function, which turns off the device when it has not been used for fifteen minutes.

The device has a comfortable handheld design and weighs less so that it can be carried around and used with ease. The meter requires 3×1.5 volts batteries to operate, and a user manual is also included so that the users can make use of the meter properly. The aspect that makes this PAR meter a top choice is the fact that it is affordable yet has a high measurement accuracy.

4) Hydrofarm LGBQM Quantum PAR Meter

The Hydrofarm LGBQM Quantum PAR Meter comes with a quantum sensor that increases the accuracy and the reliability of the meter. It can measure PAR lying between the range of 400nm to 700nm and ranging up to 10,000 umol/s.

The meter also includes a data logging feature that can be used to store data from previous measurements for reference. The data can also be copied to other devices via the USB cable. Rather than using the Gaussian response curve, this meter uses the constant linear response curve that is comparatively more accurate.

The users are notified in case the battery of the meter is low through the low battery indicator. Different calibration modes are also offered so that the users can calibrate and adjust the settings as required.

The price of the meter is just over a hundred dollars, and therefore it is not exactly an affordable option, but the features it comes with makes it worth the price tag. The functions of the meter are compatible with the more expensive options, but the price is comparatively less.
