Dimmable G4 LED bulb from Philips Lighting that is somewhat of a rarity as few other brands offer G4 LEDs with dimming capabilities.

  • Features

    Dimmable G4 LED bulb from Philips Lighting that is somewhat of a rarity as few other brands offer G4 LEDs with dimming capabilities. Providing a low energy alternative to a 20 watt halogen but consuming just 2.1 watts. 

    Like with other low voltage dimmable LEDs you need to ensure that your G4 LED transformer and dimmer switch are all compatible. We recommend using the Varilight YT50LZ dimmable transformer and the Varilight V-Pro range of LED compatible dimmer switches.

    The physical size of this dimmable G4 LED is slightly bigger at 40mm in height and 15mm diameter compared to a halogen which is approximately 33mm by 9mm so won't fit in all fittings.

    Set Descending Direction
    Could you pls confirm, is this the equivalent of LED G4 dimmable lamp 220V, 3000k/6000k/9000k?
    Question by: Zarina Torobekova on 10 Dec 2023, 00:46
    The colour temperature of this LED is 2700K. Its a G4 LED which is 12V, not 220V.
