How much light is a lumen?
A lumen is a unit that describes the amount of light provided over a given area. Each lumen is
about equal to the light output of a single candle

What is the lumen symbol?
The lumen (symbol:
lm
) is the unit for luminous flux. It measures the total amount of light emitted by a light source in all directions. Luminous flux takes into account the sensitivity of the eye to the visible part of the electromagnetic radiation.

What lumen is brightest?
The more lumens listed by a bulb, the brighter the light you can expect (and the inverse is true, the lower the lumen, the dimmer the bulb). Currently, the brightest LED bulb used for general use is rated at
5500 lumens
(although there are some consumer flashlights sold with higher lumen ratings).
Can you still buy 100w light bulbs?
They are no longer manufactured and cannot be imported.
You can only purchase them from jobbers
