Letinous edodes shed light can use light instead of insufficient
Letinous edodes can shed light on the market with light instead of ready-made "plant growth lamp", consists of LED lamp and fluorescent lamp in two forms. After testing, 40W's 4U fluorescent lamp can produce 1000-4000lux illumination in the range of 25cm distance and 40cm diameter.
LED in the form of a plant growth lamp, usually with a certain proportion of red LED and blue LED combination, made in the form of lamp and spotlight. Although the LED technology can have achieved high luminous efficiency (more than 100lm/w), but the plant growth light red LED and blue LED light emitting efficiency can reach about 20lm/w, than the general fluorescent lamp (50-90lm/w) is much lower, and the unit power price is much more expensive than the fluorescent lamp. According to calculations, in order to use LED plant growth lamp in 40cm square area to meet the normal growth of plant illumination, about 1000W LED, cost more than 10000 yuan. It's better to use a fluorescent light or a microwave sulfur lamp.
As a reference, the sunny noon sunlight above 100000lux illumination, the sun illumination sunny morning and evening is 20000-40000lux, cloudy and cloudy indoor illuminance is 5000-30000lux, close to the window but no direct sunlight illumination is 2000-8000lux. The average green plant needs illumination between 20000-50000lux. By contrast, plant growth lights provide low levels of illumination that do not meet the light required for normal plant growth.
