I did a lot of research and had a lighting expert design my layout to hit my lumens targets (he did quite well with hitting the targets). I have over $10K in my lights. They RAB commercial lights and are true 4' led lights (not tubes) and are 5000 degree. I am quite happy with them.

I used to go with lower temperatures in the old shop with fluorescent tubes, but have migrated to the 5000 degree with LED and I do like it.
