MLBL-00L is a blue LED block with built-in leakage current protection designed for 22mm modular pilot devices. It features a single diode chip integrated into the lamp block, operating at a rated voltage of 12V DC with a rated current of 9.5 mA. The LED emits blue light at a wavelength of 468 nm with a luminance of 450 mcd. This front-mounting LED block is ideal for use in pilot lights and indicator applications, and should be paired with a matching blue or clear lamp cap for optimal performance.
