Orchid light requirements in lumens?

[Ray]

In theory, 6500K is supposed to mimic the spectrum of mid-summer sunlight at noon on a cloudless day. The problem is that in fluorescent and LED lamps, it is a correlated (or corrected) color temperature, that is, designed so it LOOKS LIKE that to the human eye, rather than truly mimicking the spectrum.

If it is a plant light, then the chances are better that it will be good, but I don't think it's as critical as most think.
