Growing Orchids Under Lights

[Cape Fear]

Those numbers (~3000 K and ~6500 K) are on the boxes, so you must be correct. Notation on the boxes say red light and blue light respectively, so
I was confused. Thanks so much for your help. Cape Fear

I'm thinking of getting some LED lights as a supplement for winter. I'm going to do a very crude, minimal set up with clamp lamps & LED bulbs. What wattage should I be looking at? The way most of the plants are arranged now are on 36 inch long shelves so I wanted to do one light per shelf if possible. My collection has grown to large to rely on the windowsills alone, plus I want them to flourish during the winter. Any help is much appreciated!
