Best PAR Light Meter Reviews 2023 for LED Grow Lights

As an indoor grower, you know how important it is to have the right tools to help your plants thrive. One of the most important tools you can have is a light meter.

PAR light meters measure the amount of photosynthetically active radiation (PAR) that is present in your grow room. This information is incredibly useful because it allows you to optimize your grow light setup for your specific plants.

In this blog post, we will be reviewing the best PAR light meters on the market in 2023. We’ll also provide a buyer’s guide to help you choose the right one for your needs.

Par light meter reviews

There are a few different types of PAR light meters on the market, but we’ve found the Apogee MQ-500 to be the best overall. It’s a handheld, battery-powered device that’s easy to use, and it gives accurate readings of both PAR and PPFD (photosynthetic photon flux density).

We also like the Atomi Smart PAR Meter, which is a more affordable option that still offers good accuracy. If you’re looking for a PAR light meter that also measures Lux, the Lux Meter M2 from Illuminance Tools is a great choice.

Finally, if you need a PAR light meter that can handle high-intensity lights, such as metal halide or HPS grow lights, we recommend the Apogee SQ-520. It’s more expensive than other options, but it’s built to last and can take accurate readings up to 50,000lux.

Sun System PAR Meter with Remote Sensor

A PAR meter is a device used to measure the Photosynthetically Active Radiation (PAR) emitted by a light source. PAR is the portion of the electromagnetic spectrum that is useful to plants for photosynthesis.
