I was just indicating the amount of light without looking up the quantity in lumens. But, actually, so far, I'm still on incandescent light. For CFL, I have one, puts out about the same amount of light as a 15 W incandescent, and I have it over the kitchen sink running 24 x 7, e.g., as a kitchen "night light". My issue is simple, all in just one word -- seeing. I need to see clearly inside the case when building and/or maintaining the computer. It's not about the heat or cost of electricity for the light. It's just about seeing clearly, e.g., each screw, wire, cable, socket, etc. Inside a black case, it's tough to see clearly without a lot of light. So, on the outside, maybe I'll get a spray can and paint it white. On the inside, maybe I'll get a brush and some cheap white paint and give it quick, crude job of painting it white without covering over small holes. Ah, I was frustrated, kept hoping some case manufacturer would get away from black. But, sure, there's an easy solution, for much less trouble than shopping for a beige or white case -- just go ahead and accept a black case and just repaint the thing. Then back to my business.
