How to choose the grow lights? LED,fluorescent or incandesc

 
There are so many types of grow lights on the market. How do you find the best one for you? Here are some basic knowledge for reference.
 
Basic knowledge of grow lights
 
We know that almost all green plants need light for photosynthesis. In this process, plants absorb light energy, synthesize carbon dioxide and water into organic matter, and release oxygen that both animals and humans are needed to survive.
 
How much light does the plant need to thrive? This is very different. Low-light indoor plants, such as Scindapsus and Rich Bamboo, can also grow well in darker rooms, and only a short time in the day can reach the sun without affecting their normal growth. Fruit plants, such as Pitaya and Tomatoes, require brighter light, and these plants prefer to absorb a lot of sunlight outdoors, especially in winter.
 
Below we introduce related technical terms to help understand.
 
Lumen-is a physical unit that describes the luminous flux. Physics explains it as the total emitted luminous flux produced by a candlelight at a solid angle (on a unit sphere with a radius of 1 meter). The higher the lumen level, the brighter the light.
 
 
Light Intensity--Describes the amount of light that reaches the surface of the light source over a certain distance. For example, a super bright light bulb at a long distance may produce the same light intensity as a low light bulb at a short distance.
When you use plant lights for plants, you can adjust the light intensity in two ways: by the brightness of the bulb and the distance of the bulb from the leaves of the plant.
 
Lighting Duration-refers to the amount of light the plant receives within 24 hours. Outdoors, the lighting time varies with location and season. For example, the farther you are from the equator, the shorter the winter daytime (hours of daylight).
 
Indoors, we can control the duration of the light by turning on and off the plant lights. Some plant lights will have a settable timer function.
The common practice is to let the plant light turn on for 16 hours a day, then turn off the light to allow the plant to rest for 8 hours, and then turn on the light for 16 hours ... this cycle.
 
Most plants need to turn off the lights and rest for a period of time, during which they use some of the energy collected during the day to promote growth. Some plants, such as Epiphyllum and Pitaya, bloom only at night.
 
In particular, seedlings need a lot of strong light, and when they do not get enough light, they become weak. In most cases, even the most sunny balcony where cannot provide the required light intensity, and you need grow lights to supply the light. The grow lights adjustable rope hanger can make the seedlings get the required light. When the seedlings are tall, you can adjust the distance between the grow lights and the seedlings by adjusting the rope, about once a week to keep the plant lights and leaves at a few inches.
 
LED, fluorescent or incandescent?
 
LED plant lights are the best choice because they save energy and power. LED plant lights consume only half the power of fluorescent lamps, but have a service life that is five times that of fluorescent lamps, do not contain mercury, and do not break like glass.
Ordinary incandescent light bulbs are not used for indoor planting, because they release too much heat, they will burn young leaves, and they are not in line with current energy saving and environmental protection concepts.
