This Osram LED Superstar MR16 lamp is dimmable, but it does not always work properly with older trailing edge phase cut-off dimmers. It is important that the dimmer is compatible with LED lamps, as many older dimmers are only designed for halogen lamps and may not work correctly with LED lamps.
It is recommended to use a dimmer that is specifically certified for LED lamps to ensure a stable and reliable dimming function.
