👉 Lums, also known as Luminous, are a type of light source that is commonly used in scientific research and engineering. They are characterized by their ability to produce high levels of light without any visible emission, making them particularly useful for experiments where long wavelengths or intense sources of light are required. Lums can be classified into two main categories: direct lums (also called "diodes") and indirect lums (also known as "luminescent diodes"). Direct lums
