How much is 500 lm?

Excuse me, could you please clarify what you mean by "500 lm"? I'm assuming you're referring to a unit of measurement, but "lm" is not a commonly recognized abbreviation in the field of cryptocurrency or finance. Could you be referring to something related to lighting, such as lumens, which is a measure of the total quantity of visible light emitted by a source? If so, then "500 lm" would simply mean 500 lumens, which is a measure of brightness and doesn't have a direct monetary value. If you're asking about a specific cryptocurrency or financial instrument, perhaps you could provide more context or use the proper abbreviation to avoid confusion.
