Light and plants to choose

[Vanda_lover]

Hi there ,

I am planning to make my own orchidarium. I have a problem to choose orchids as tank is coming with lights already . I found orchids that needs 2000-3000 foot candles , or 500-1000 foot candles. Description of ligthing in my tank says : The continuous wavelength output of the LED’s is between 400nm – 800nm. However there are two main peaks between 420nm-450nm and 630nm-650nm, with a minor peak between 540nm-570nm. These LED’s closely resemble a natural light output that is similar to the sun.
The Biopod has a UV emitting diode which emits UVB-B rays. The specific wavelength of UV rays emitted is between 295-305 nm.

So - how do I know if I should choose orchids with 2000-3000 foot candles or others?

Thank You for your help
