The LEDVANCE OSRAM LED ST MR16 is a direct LED replacement for GU5.3 low-voltage halogen lamps. Its compact, all-glass single-optic design fits the same MR16 housings already installed, and the 2700K warm white output starts instantly with no warm-up delay.

At 3.8W nominal consumption and 345 lm output it is suited to accent and spotlight applications in retail displays, residential interiors, museums, and galleries. For outdoor use, it must be installed in a suitable enclosed outdoor luminaire.
