Flexible is characterized by high-quality standards, starting with the use of a flexible brass arm (0.47" diameter), which guarantees solidity and prevents squeaking, even after prolonged use. Advanced engineering and the efficiency of the LED ensure that the temperature on the lamp head remains within the correct limits, even after 24 hours of uninterrupted use.
