Grow lights are artificial light sources, usually electric, designed to stimulate plant growth by emitting an electromagnetic spectrum suitable for photosynthesis. Grow lights are used in applications that do not have natural lighting or require supplemental lighting.

LED grow lights are usually composed of multiple individual light-emitting diodes in a casing with a heat sink and built-in fans. Most or all LEDs use AC/DC or DC/DC power supplies that provide constant direct current through the LEDs, regulating the amount of total power the LEDs can draw and preventing their failure.
Individual LEDs usually provide only a single narrow range of colors, and so different color LEDs are mixed in grow lights in proportions depending on the intended use. It is known from the study of photomorphogenesis that green, red, far-red and blue light spectra have an effect on root formation, plant growth, and flowering, but there are not enough scientific studies or field-tested trials using LED grow lights to recommend specific color ratios for optimal plant growth under LED grow lights.It has been shown that many plants can grow normally if given both red and blue light. However, many studies indicate that red and blue light (pink to purple depending on the red to blue ratio) only provides the most cost efficient method of growth, plant growth is still better under light supplemented with green.
White LED grow lights provide a full spectrum of light designed to mimic natural light, providing plants a spectrum of red, blue and green. White light is rated on a spectrum in terms of Color temperature where cooler lights produce more blue photons and warmer lights produce more red photons.
A large number of plant species have been assessed in greenhouse trials to make sure plants have higher quality in biomass and biochemical ingredients even higher or comparable with field conditions. Plant performance of mint, basil, lentil, lettuce, cabbage, parsley, carrot were measured by assessing health and vigor of plants and success in promoting growth. Promoting in profuse flowering of select ornamentals including primula, marigold, stock were also noticed.
To prevent leaf burn, LED grow lights should be kept between 12 inches (30 cm) away from plants for lower wattage lamps (under 300 watts) up to 36 inches (91 cm) away from plants for higher wattage lamps (1000 watts or more).
LED grow lights are often priced higher, watt-for-watt, than other LED lighting, due to design features that help them to be more energy efficient and last longer. In particular, because LED grow lights are relatively high power, LED grow lights are often equipped with cooling systems, as low temperature improves both the brightness and longevity. LEDs usually last for 10,000 – 50,000 hours until LM-70 is reached.
Advantage of LANGY LED GROW LIGHT:
Energy savings:
The LANGY LED GROW LIGHT solution demonstrates the potential for 40% electricity savings, and studies show that LED-lit canopies can generate more output per kWh.
Plant and Crop Performance:
Preliminary research suggests that growers using LANGY LED GROW LIGHT lighting may experience increased yields and changes in cannabinoid and terpene composition, resulting in more consistent drug composition from harvest to harvest.
Less maintenance:
The LANGY LED GROW LIGHT is rated for 60,000 hours of use and comes with a market-leading 5-year warranty.
Reduce HVAC:
LANGY LED GROW LIGHT is highly efficient and the lower the wattage, the less heat enters the space, potentially reducing HVAC loads and operating expenses.
Safety:
The LANGY LED GROW LIGHT driver is smart with full circuit protection including over/under voltage, short circuit, and over-temperature protection. The driver also has the ability to automatically increase/decrease power to match the number of strips connected to the fixture, and all grow lights are CE-certified to LVD and EMC standards.
Flexible light intensity:
LANGY LED GROW LIGHT can be dimmed to adjust PPF levels to suit the crop and growth stage without altering the spectral power distribution or losing efficiency.
