Suggestions for indoor lighting for an orchid wall

[kflickin]

Hi, I live in central eastern Colorado, I have multiple orchid genus, too many for my windows in my house and am hoping to get my orchid wall in my office going. I plan to put in a humidifier to compensate for the lack of humidity in Colorado. My question is: what type of lighting is best for successful growth and flowering of different genus of orchids? Any recommendations are appreciated!

The keys are wattage and distance from the plants. I highly recommend LEDs from theorchidhobbyist.com
