GU5.3 LED bulb 7W black/chrome with ambient dimming, 12 V This GU5.3 LED bulb with black base and shiny silver head with transparent cover is an energy-efficient replacement for halogen reflectors in many areas. The reflector LED bulb, which is dimmable with most common dimmers, changes its light colour with the dimming process thanks to ambient dimming. From 3,000 K warm white, the light becomes increasingly warmer with dimming down to 2,000 K. - Beam angle 40° - Dimmable with most commercially available dimmers - Particularly high switching resilience with 100,000 switching cycles - Low-voltage bulb (12 V AC/DC)
