What is Par Light Measurement?
You start to notice a change in color pigment in plants that do not have access to direct sunlight and this is because the area of such plant does not feed well. By feeding, we mean photosynthesis which is a daily growth requirement for plants. However, farmers who have to grow their plants indoors or in places that don’t have access to direct sunlight have to do this by providing growing lights. With a growing light, you will need a par light meter.
Now, to explain what a par light measurement is, there is a need to explain what par itself means. Par simply means photosynthetically active radiation and it is this radiation that causes photosynthesis to happen to plants. The sun will reflect different light wavelengths on your plant at a time and it is only the PAR that is needed to make photosynthesis happen. The remaining light wavelengths are useless and not needed for your plant.
Just like the sun, a grow light will also reflect a lot of light wavelength. Since all of these different light wavelengths are not needed by your plants, you will need a par meter to measure the amount of par light needed or essential for your plant’s optimal growth.
How to Pick the Best Par Light Meters?
Many brands are manufacturing so many types of par light meter but to own an outstanding meter, here are some outstanding features they must possess:
Compatibility with All LED Lights
You don’t want to own a par light meter that works with a single color LED light. The essence of having to use a grow light for your plant is to help them achieve all the possible essential light they need for their growth and this might not be achievable if the LED light is of the color that isn’t compatible with your par light meter.
Hence, instead of trying to settle for a par meter that sees just a single color, you should go for meters that can see and that is compatible with all colors of LED lights. Going a step forward, your meter shouldn’t just see only LEDs but also all types of standard lighting.
The number of settings a meter can switch between, in terms of measurement, goes a long way in attesting to the outstanding nature of such a meter. The Par meter should come in measuring range that will adequately help you in keeping good track of light all through the day, and to make sure every plant gets adequate light. A good meter should have a minimum of four-range setting which will adequately measure light in the different desired types of measurement.
You do not want to squint your eyes while trying to read the par measurement on your meter. This is why your meter must have a large LCD screen with readable letters and figures. This makes it easy to use without having to use your glasses, for those that read with one. The best par light meters come in pretty impressive color LCD screen with digital colors while some also come with a dual or single-color LCD screen. However, the most important thing about screen size is the legibility of the meter's displays.
For one reason or the other, having the right light in a space matter a lot and because it matters, that is why you need any of these best par light meters to help you adequately take care of your light need.
From the number of range settings they can operate with, sturdy and appealing exterior design to how large the LCD should be, we have carefully selected the top eight choices that buyers like yourself have attested. We can assure you that buying any of these products will do more than what many other average par light meters have done for you.
