    You are going to get a myriad of opinions on this. I have been to a lot of lighting seminars and have gotten a lot of different answers. The common thread, though, is that the real issue is glare control. More effort is made to control glare than to determine the best light source, especially in an office setting. In a computer setting, for optimum energy efficiency and glare control, most are now built with indirect fluorescent fixtures with either T8 or T5 lamps (bulbs). Basically, a lot of computer geeks like to turn off the lights, but studies show that your eyes need good ambient lighting when you are working on a computer. Controlling glare creates a soft light that facilitates this. Look at this very common type of light fixture for computer room applications.

    also, incandescent lighting (bulbs) causes less eyestrain in general than fluorescent lighting does

    Curtains on all the windows and lights off isn’t the best choice.

    If you elect to have no curtains make sure that people dont’ have their computers either so they are facing the window or the window is directly behind them as this will cause glare issues. Best way is desks perpendicular to the window.

    Having curtains is fine…provided you have sufficient lighting. More lights are better as they will help reduce shadows.
