I have been using florescent tubes in my lab, but I need to change them now. I have seen there is a large variety of led lights offered as alternative, but I do not know which ones are preferred for the growth of plants in the lab.
Reasoned suggestions are welcomed!
The ideal LED colour for plant growth is actually a mix of red and blue light.
Here are some sources for this;

Plants will grow under all visible wavelengths of light, however they will have different morphologies due to the colour. Generally for lab growth, white or a combination of red, blue, and green LEDs are used. While blue and red light are highly absorbed by chlorophyll, the addition of green or other wavelengths are still usefull for various physiological and biochemical processes.
