The problem with capitalism is that companies would do anything to make you buy their products. Long gone are the days where companies tried to entice you into buying what they had to offer by making top notch stuff. Instead, they try to trick you through marketing, and often they use gimmicks that you would easily fall for even if you are generally a smart and sensible person.
One good example can be seen in the case of flashlights. You obviously want to buy a bright flashlight so that you have the potential to see as much as possible if it becomes your only light source. Companies manufacturing flashlights know this and they use it to their advantage. A common marketing gimmick that they use is referring to the luminescence of their flashlights in terms of candlelight. For example, a flashlight might be marketed as having one million candlepower. On paper this sounds pretty amazing, and it might make you feel like the light you would get is extremely bright. However, candle light is really not that bright, and even a million candles are not going to give you the sort of brightness that you might expect from a number that large.
This is without a doubt just a cheap marketing gimmick so you should try your best not to fall for it. Candlepower is not an accurate description of the luminescence of a product, and a trustworthy company would never use it to try and trick you into buying what they have to offer.
