Why are watts important

Voltage and Amperage markings are required per safety labeling on the appliance. However for advertising proposes just about anything can be used to attract the customer. For eg: You may want to conserve power so you buy the lowest wattage device, or you want the strongest car battery so you look for the highest cold cranking Amp rating.

There are a lot of devices, where watts is the output, and voltage and amps is the input. For example my microwave states it is a W one, but it says that it draws a max of 6A. This can be especially true for all kinds of power supplies where the DC wattage is specified, but the AC power draw is higher, due to losses.

Also on quite some devices, wattage is a pure marketing number, giving some kind of overall power, whereas the momentary amps it draws can lead to much higher values for short times.

One foot-candle, as the name implies, is the equivalent of the light from one candle, measured at a distance of 1 foot from the center of the flame.

One lumen is the amount, or flow, of light that distributed uniformly, produces illumination of 1 foot-candle on every point across over 1 square foot of surface area. You might think that you want a watt bulb in a lamp, for example, when what you're really after is for that lamp to be as strong as what you're used to seeing from a lamp with a standard watt incandescent bulb in it. That means this bulb produces approximately the same lumens as a standard watt incandescent bulb.

Sometimes watts matter.
