Lighting Standards also serve to address the plethora of other concerns associated with the design, placement, installation, and minimum energy requirements and efficient allocation of illumination in different locations with different purposes, as well as the efficiency, durability, cost, and maintainability. When a plant is indoors, light usually only comes from one source, like your sunny window, massively reducing the angles light is bouncing off from, and the amount of light and vital photons a plant needs. Results - Yield Lab Brand HID Grow Light Systems We completed the PAR rating for all HID Yield Lab Grow Light Systems. The plants respond well to artificial light, as long as you meet their color requirements and time needs. Long day plants flower when nights are under 12 hours long. Defining light… 4,000–5,000: About 50 percent of the midday sun, or strong direct sunlight in a bright room, good for plants with high light requirements; 5,000 and up: Very bright indoor light; When considering foot-candles, it's good to remember that full sun outdoors is about 10,000–12,000 foot-candles, so even the brightest of indoor rooms rarely approaches that level of sunlight. More scientific measures for plants are PAR watts or PPF. This is the 1000w, 600w, and 400w HPS grow light system measured over a 4x4 area at 18 and 24” in height.
