How it's used
Technical specifications for lighting and display equipment rely on this unit to describe brightness levels. It is treated as a standard noun in Cantonese rather than a verb or adjective, functioning similarly to other scientific units like 瓦 or 伏特. You will mostly encounter it in product manuals or when discussing home theater setups and professional photography gear.
Examples
How many lumens does this projector have?
This light bulb has an output of two thousand lumens.
