@drdawg I am growing radishss, spinach, lettuce, herbs. I wondered if the new LED lights would work well and found a positive review on those. and they come in 6500K.

My big challenge is my 6 x 8 GH isn't really tall enough for a shop light. Today I used some clip-on lights (the kind with the metal hoods) and CFL 6500K bulbs. They were hot to the touch and I really didn't need the heat in there today as it was 71 degrees here. I had to leave the door to the GH open and hope the deer didn't wander in. Had a Hard time finding something to clip them to at the appropriate height so they didn't cook the plants. So I'm thinking about those LED lights.
Here's one that I could put in the clip on
