Many gardeners seek to extend the growing season by growing herbs, leafy vegetables and flowers indoors using grow lights. In the past, growers used fluorescent bulbs to provide the necessary light for plants growing indoors. LED (Light Emitting Diode) grow lights are a fairly recent innovation, comparable to the compact fluorescent light bulbs now used for general lighting purposes in many homes.
LED grow light is the newest generation of grow lighs, having advantages compared with HID and LED.In the last years, LED technology has advanced significantly and is now available as an alternative to incandescent bulbs and compact fluorescent lighting (CFL) bulbs for various lighting needs. Numerous studies and field test have resulted in several practical uses for LEDs.
- 1.LED is more efficient, it can save about 30% engergy , compared with HID or HPS
- 2.the spectrums are good, always full spectrum, with higher red and blue lights, which are good for photosynthesis, helping your cannabis grow faster
- 3. nature, about the heat, what plants like is the energy carried by solar light. The energy contains heat.
- If we give cannabis the light they desire, the energy is enough for them to grow
- Actually, too much heat is not good, it may burn the leaves of the plants
- 4. thus comes the 4th advantage, LED will not generate much heat and always comes with a self-cooling system. You do not need to equip with much cooling system in your growing area
LED lighting is fundamentally different from conventional light sources such as incandescent, fluorescent, and gas-discharge lamps. An LED uses no mercury, no lead, no gas or filament, it has no fragile glass bulb, and it has no failure-prone moving parts. LED sources are super green! They do not contain mercury (as do CFLs) or lead (as do incandescent lamps). LED lighting is more efficient, durable, versatile and longer lasting than incandescent lighting. … In a well-designed product; LEDs are basically cool to the touch [and emit visible light as specific colors].” Source: https://www.ies.org/lighting/sources/led.cfm
