There are a number of online resources available that will provide optimal lighting levels for various plants and food crops. Our standard light meters measure light in Lux, lumens and/or foot candles, the UV light meters (which measure UV light) measure in uW/cm2. This metric is important to measure since the amount of light your plants get in a day relates directly to plant growth, development, yield, and crop quality. Here is the formula for calculating DLI with a quantum meter. The following graph illustrates the year-round variability of global horizontal irradiance at Apogee Instruments in Logan, Utah. How many light day in 1 meter? This factor is the total number of seconds in a day divided by 1,000,000. It’s not possible to use a constant multiplier with variable lighting, so a quantum meter that has an integrating capability is necessary to determine the daily light integral under variable lighting.

A unit of measure of the amount of light hitting a surface that is in the range of 400-700 nanometers. It’s not possible to use a constant multiplier with variable lighting, so a quantum meter that has an integrating capability is necessary to determine the daily light integral under variable lighting. Measuring DLI over a growing season and comparing it to results can help a grower decide which varieties work for his or her location. It is determined by multiplying the instantaneous PPFD by the number of seconds in the photoperiod. In greenhouses or growth chambers, DLI values are typically much lower, which can affect the shoot/root ratio, morphology, and the timing of flowering.

Once an accurate measurement is made it is important to interpret that measurement – it's nice to know that those impatiens are getting 10 mol m-2 d-1, but is this enough to grow healthy plants? Foto-tabel  A light meter is used to measure the amount of light in your location. {Impatiens Walleriana Photo by http://www.hear.org/starr/ } How intense light (PPFD) to expose various species to and for how long.Light intensity, or rather, how densely packed light is with photons, is measured in micromoles per meter squared per second, µmol/m2/s. A light meter is used to give important information about exposure, shutter speed and aperture in order to take the perfect photo or footage. Whether it was a steak, some pork chops, or even just a couple hamburgers – you likely had a vision in your mind of what the finished product would be. It can even give detailed graphs and charts about the quality and colour of the lights being used. The term “daily light integral” refers to the number of light particles, or photons, received during one day in a particular location and area. Light meters are used to measure the amount of light to determine the proper exposure for a photograph. DLI is directly correlated with plant quality, and a minimum amount of light is required for marketable plants. We assume you are converting between light day and metre. The Apogee MQ series meter is designed to measure and store this value each day. A measure of radiant light from a standard candle that falls on one square meter of surface area one meter from the source.
