I finally stepped up and ordered some brighter studio lights.
I ordered some Genaray LED lights from B&H which are rated about 5x brighter than the lights I'm using, and run very cool, so no heating up my small basement office space.
My other next step is probably going to be to install a background hanger on the wall at which I shoot pictures. The wall here is a light textured gray which is a bit distracting for photos, though not horrible. It's either that or just repainting the walls white.
I would recommend painting the wall, I had a backdrop and it got wrinkled and looked bad. I just painted the section I use for photos a matte white. With your lights I think it will be much better.
New setup with painted wall. Need to get another light from overhead to get rid of that shadow.
Old setup with backdrop. Notice the wrinkles.
