Remarks Colour Temperature changes from 2700K to 1800K when dimmed from 100% to 10%. The rated wattage, rated lamp life and rated luminous flux are equivalent to their nominal values shown on product packaging.

Following exactly the dimming curve of familiar incandescent and halogen lamps, the LED lamps could simultaneously emit a warmer light when they are dimmed from 100% to 5%.
