When most people buy a light bulb, they look for watts (W). Recall that watt is a unit of power, (i.e., the rate at which energy is consumed from the electricity supplier). It does not say anything about the light.

Eyes are the organs of vision. Through a complex process, they detect and focus light to create images. Vision begins when light rays are reflected off of ...

Lumens are a measure of brightness. So if you know how many lumens you want, you’ll buy just the right bulb for any spot in your home.

The KMQ is an ultra-compact OLED light-meter designed for analogue cameras. With a size comparable to a sugar cube, the KMQ's compactness redefines ...

Here’s something to consider. In the past, we bought light bulbs based on how much energy—or how many watts—they use. But today’s energy-saving light bulbs use up to eighty percent less power to give you the same amount of light. So wouldn’t it make more sense to buy light bulbs based on how much light they provide? With lumens, you can do just that.

The most common measure of light output (or luminous flux) is the lumen. All lamps are rated in lumens, as shown in the figure below, and every bulb has 3 parameters listed on the package:

A 40 watt bulb produces about 505 lumens and has a life of about 1,000 hours. When this bulb is used to light a room of 10 x 10 feet, these 505 lumens are distributed over 100 square feet of floor area. What is the illumination?

With more energy-saving choices appearing on store shelves, including compact fluorescents, or CFLs, light emitting diodes, or LEDs, and energy-saving incandescents, you’ll have more options that save you money.

A footcandle (fc) is the Standard unit of measure for illumination on a surface. It is a lumen of light distributed over a 1-square-foot (0.09-square-meter) area.

Today you’ll see more light bulb options in stores. These bulbs will give you the light you want while saving you energy—and money.
