I have an Ott light mounted right over my workspace, I don't find it bright enough. So I have added another daylight florescent and also a 60 watt incandescent. With all those bulbs it is OK but I would still like it brighter.
The Ott light is only 40 watts, and it's not cheap, even replacement bulbs run about $30. It's great where daylight affects colors like fly tying but I don't see any great advantage to rifle building. I use it only cause it's on my workbench.
