Proxima Centauri appears dimmer than Betelgeuse because it actually is dimmer by several orders of magnitude.
Proxima Centauri has an insignificant luminosity to Betelgeuse. Although it is the closest known star(4.2 light-years) to our Sun, it is virtually impossible to see because it is so dim. Betelgeuse, on the other hand, is a lot farther (640 light-years). Yet, it is one of the brightest stars in our night sky. This is because Betelgeuse has an extremely high luminosity.
When you look up at the sky at Proxima Centauri, you see it as it was 4.2 years ago. It will be another 4.2 years from now before somebody at Proxima Centauri sees you looking down at him. He will be troubled, and will wonder why you are looking down at him.
That light is 4.2 years old.
Alpha Centauri is a triple star system. Alpha Centauri A, B & C or Proxima Centauri. Alpha Centauri A & B are 4.37 light years from the Earth whereas Alpha Centauri C is 4.243 light years.
Technically speaking the closest star to Earth is the sun which is about 93 000 000 miles (150 million kilometers) away. After that the next nearest star is Alpha Centauri and it is 4.37 light years away from our sun.
Betelgeuse is a star, so there is little chance that anyone lives on it.
It is simply because they are much farther away. The nearest star to our sun is Proxima Centauri, at a distance of 4.2 light years, about 265,000 times farther away than the sun is.
Look on the carton that the dimmer comes in. On the label there will be a list of lamp types that the dimmer can be used on along with the maximum wattage that the dimmer can control.
I saw it last night. Betelgeuse is one of the brightest stars in the sky, you just need to know where to look and it's easy to see.

Betelgeuse is bright because it is a huge star known as a red supergiant. If it was where our sun was, it would be big enough to extend out beyond the planet Mars.
Because it is still really far from earth
