I put a brighter but whiter flourescent bulb in my mag lamp at one point. I liked the color and the increased brightness, but I went back to the dimmer, yellow, fuller spectrum bulb. Even though it looks way dimmer, I found there was significantly less eye strain when I was working on small things.
I tried upgrading to a bright white LED mag lamp that had more lumens, but that was even worse. To be fair, I'm not sure what was worse between the color or the insufficient diffuser. I repaired my flourescent mag lamp for the 4th time and put the LED lamp in the garage.
I also still use a halogen lamp. I repaired it when the lamp broke and swapped some parts out with a modern bulb lamp. They still sell the halogen bulbs, but the halogen lamps are no more for sale, here, due to being a fire hazard.
Now that I use the stereomicroscope for detail work, I don't really care so much about my general lighting. Whiter light appears brighter and does seem to have a positive effect on my mood.
