Which statement about the cold beam laser level is not true?

The statement regarding the cold beam laser level projecting a beam of ultraviolet light is not true. Cold beam laser levels utilize a laser beam that is typically red or green, which is visible light rather than ultraviolet light. These devices work by creating a highly accurate laser line that can be used for leveling tasks, making them invaluable for various construction and plumbing applications. The primary features of cold beam laser levels include their effectiveness in providing precise horizontal leveling and their common applications in indoor environments. Additionally, many models may be designed to operate without batteries, often relying on other power sources or technologies that enhance their usability in the field. Understanding the proper functionality of these levels is critical for tradespeople to ensure they choose the right tools for their leveling needs.
