    How Should We Design Office Lighting?
    Linear lighting will play an increasingly important role in the office environment of the future. In addition to providing sufficient light for the office, it will also enhance people's comfort and work efficiency in the office.As we all know, when there is not enough light, it will lead to visual fatigue, physical fatigue and even headache, which will lead to concentration problems and affect productivity. Likewise, when the light is very harsh, the TV or computer screen will look gray...

    Specific Grow Light Spectrums and Their Application in Horticulture
    UV Light Spectrum (100–400 nm) UV light spectrum, which is not visible to the human eye, is outside the PAR range (100nm-400nm). Around 10% of the sun’s light is ultraviolet, and like humans, plants can be harmed from overexposure to UV light. Categorized into 3 types, UV-A (315-400 nm), UV-B (280-315 nm), and UV-C (100-280 nm).  While the benefits of ultraviolet light use in horticulture are still being researched, UV light is often associated with darker, purple coloring – in...

    What is the PAR and PPFD?
    PAR (Photosynthetically Active Radiation) describes the portion of the visible spectrum that plants “see” and use for photosynthesis (400nm-700nm). PPFD (Photosynthetic Photon Flux Density) measures the amount of light (PAR) a plant receives over time. PPFD represents the light density a plant receives over time and is measured in micromoles [of photons] per square meter per second (1).A way to visualize PPFD is to imagine the sun is “pouring” light onto the plant leaves. As the sun pours light onto...
