light can help you do better
Do you know how many footcandles you need to read a magazine? Most likely not, and there is no reason you should. But you are an expert at what you do in your home, and you need light to see it. You need a certain kind of light to read your magazine, light that illuminates the page without causing glare on the glossy paper. You need a certain kind of light to chop vegetables in the kitchen, a certain kind of light to comb your hair in the mirror, a certain kind of light to knit or read a book. This is light for doing, and it is the most basic of our needs. And of course we do know how many footcandles you need to read a magazine, and we’ll help you get there.
When we buy a light bulb or a light fixture today, the most prominent feature quoted is often the “lumen output,” a measurement of light coming out of the fixture. We assume that a certain number of lumens must be enough for us, or we get more lumens because we cannot see our counters well enough. Unfortunately, lumen output tells us almost nothing about whether the light is going to provide what we need for chopping vegetables. We will balance lumens with geometry, distribution, shielding, and other technical considerations to help you get light for doing.
