Let's face it: fluorescent lights are ugly. It's not so much that the lights themselves are ugly (in fact, they can easily be hidden). The issue is that the light they cast is ugly. Nonetheless, there are places where a fluorescent light is appropriate. In this article, I will discuss cases where you should consider using fluorescent lamps.

The problem with fluorescent light is the spectrum of light that they cast. Incandescent lights provide a smooth light that leans toward the pink end of the spectrum. In other words, incandescent lights provide light that includes the full spectrum of white light, with a little extra red. In addition, this light is smooth. If an incandescent light provides light of a certain hue at a certain brightness, it will show light of a similar hue at a similar brightness. Fluorescent light, on the other hand, is both green and spikey. Rather than lean to the red end of the spectrum, which is a warm light that looks good on flesh, it leans to the green end, which makes people look sickly. Worse, the light is spikey, meaning that it has hues that are especially brought out, but the nearby hues are much less so. This can actually make things look very uneven.

Nonetheless, there are some real advantages to fluorescent light. They have three advantages. First, they are more energy efficient than incandescent bulbs. Therefore, if you have a place where you don't care about appearance, like in a personal workshop, then they might be the best choice. Second, they do not need to be replaced as often as incandescent bulbs. Therefore, if you have a large space like a large garage where the light is inconvenient to replace, you should do so. Note that fluorescent lights don't "burn out" like incandescent bulbs, but should be replaced when they flicker. Finally, they can be much larger than incandescent lights. Therefore, they can be useful for lighting large surfaces from a relatively close distance, such as task lighting in a laundry room over the ironing or folding areas.

Fluorescent lights therefore do have some uses, provided one is aware of their inherent disadvantages.
