Now testing the Quantum Boards with 288 pcs SMD LED Chips.
For over 150 years, plant-growth practitioners have studied the effects of light on plant ecophysiology. Light can have a major impact on horticultural success, with parameters including quality and quantity all contributing to plant growth factors such as dormancy, stem extension, root growth, and flowering.
Farming in a controlled environment enables growers to manipulate lighting to boost yields. Identifying the optimal system can prove to be difficult and growers wanting to gain a competitive edge would therefore benefit from independent tests to verify the performance characteristics of the lighting products they are using.
To optimise operational success, testing and verification of the correct lighting products and light combination will help to identify the impact on growth rate and nutritional value so that appropriate measures can be defined, such as product design and adaption.
Before we go ahead, talking the price. if you ever buy this product, how much is it? I think it should be less than $130. LOL.

At the first, i want to testing the PPFD, it is important for garden lover.
PPFD Testing at different distance(2 ft/ 10 inch)
PPFD stands for Photosynthetic Photon Flux Density, and is the same as PPF, but takes surface area into account as well. PPFD is measured in micromoles per meter squared, per second (µMol/m2/S). In the world of lumens, PPFD would be most similar to lux or foot-candles: PPFD measures the number of PAR photons hitting a certain area, while lux and foot-candles measure the illuminance of a surface in lumens per square meter or foot. For most indoor growers, PPFD is commonly measured with relatively inexpensive quantum meters like the Apogee . I also buy this one pcs from Apogee.
If you want to find out the true light intensity of a lamp over a designated growing area (e.g. 4’ x 4’), it is important that the average of several PPFD measurements at a defined height are taken. Lighting companies that only publish the PPFD at the center point of a coverage area grossly overestimate the true light intensity of a fixture. A single measurement does not tell you much, since horticulture lights are generally brightest in the center, with light levels decreasing as measurements are taken towards the edges of the coverage area. (Caveat Emptor: Lighting manufacturers can easily manipulate PPFD data. To ensure you are getting actual PPFD values over a defined growing area, the following needs to be published by the manufacturer: measurement distance from light source (vertical and horizontal), number of measurements included in the average, and the min/max ratio).
Do you have warm light at home? I think most of you will have that, the light spectrum is same, check below chart of this led grow light.
