Summary:LED lamp adapted to be used with a single variable drive circuit, where the drive circuit comprises an analog variable voltage or current, where the lamp comprises a first LED string with at least one LED having a first wavelength, where the LED lamp comprises a second LED string with at least one LED having a second wavelength, where the first and second LED string are connected in parallel directly to the single drive circuit and where the first wavelength differs from the second wavelength such that the wavelength of the luminous flux of the LED lamp can be shifted when the current of the drive circuit is varied. The advantage of the invention is that a LED lamp that can replace a conventional incandescent lamp and that can be used with conventional dimmers is obtained.
