Suggestions to convert shelf to grow light set up?

[Cheddarbob14]

I'm a complete novice to growing under lights. Have been reading a lot of the threads here that last few days. Have reached an information overload point! I've got a great shelf setup, that I think could easily be converted to a grow light area for my orchids. Would really be interested in hearing what you pros would suggest. Would love to go an led route for the long term cost savings, but open to any ideas. Each shelf is about 12 inches deep, by about 30 inches wide, and 12 inches between each shelf. My initial thought is led light strips that could easily be slapped onto the bottom side of each shelf. Thoughts?Thanks in advance!

Edit, some other pertinent information: the only time my orchids ever go outside is during a nice easy rain, that shelf sits immediately adjacent to an east facing bay window, another kitchen window to the right. Brief direct sun in the morning, very bright until early evening. I have 4 phals, 1 paph, 1 dendrobium, 1 vanda, about 10 oncidium types, and about 10 cattleyas. Mostly higher light lovers, which currently sit in the bay window area. Cattleyas have the slight purple tinge in their leaves so they do enjoy where they are at, but I like to move things around quite often and would like to be able to utilize the shelf.
