What is bril as a luminance unit?

Bril is a nonstandard, possibly proprietary or local luminance unit with no widely recognized definition; its meaning should be confirmed from the original source.

Why convert bril to lumen per square foot per steradian?

Converting bril to a recognized customary luminance unit helps interpret legacy or proprietary brightness data in practical lighting and signage applications.

Is bril recommended for scientific measurements?

No, bril is generally discouraged in scientific or engineering contexts because it lacks standardization and clear definition.
