i want to confirm from experts that how many LED lights are needed to cultivate microalgae species. one LED is equal to 40 watt. i need 20 micro mole per meters per second

The light requirements for optimum growth are species specific. And different microalagal species respond differently to both light intensity and wavelengths.
Further other parameters like carbon dioxide supply, nutrient availability, may also affect the light fixation rate.
And plenty of research is available on researchgate.
The title seems different from the question itself.
To answer the Q, I want to know the following.
(1) 40 W seems big. Do you use a panel of LED array. What is the size?
(2)irradiance depends on the distance between LED and the culture vessels.So, what's the distance.
Anyway, 20 micro/m2/s is relatively low. For example, the irradiance of desktop in usual offices may range 4 to 8 micro. So, to get 20 micro you may not need 40 W LED. Or, you use a big tank for culturing?
In our center, Marine micro algal species being grown mostly between 15 and 35 degrees C.
Ok. Dear M.P! I need isolated culture of scenedemus obliqus. Is your center can help me in this purspective? I will purchase them for my research work.
