    Set Descending Direction
    Dear Sir/MADAM,
    Can I use this gu10 without have a dimmer at my home? I mean to use the dimmer option in the future, and for the time being not?


    Question by: Sevroglou on 29 Dec 2022, 22:08
    Yes, that's fine. Just because its dimmable, it doesn't have to be dimmed.
    Answer by: Chris Horridge (Admin) on 30 Dec 2022, 07:08
    Do these bulbs go yellow over time as this is an ongoing issue for me with my current bulbs.
    Question by: Peter Rogan on 12 Aug 2023, 21:37
    No, they don't. Philips LEDs produce a consistent and high quality light over their entire lifetime. These are a premium version of a premium brand, you won't go wrong with these.

    They also have a 5 year guarantee. Sounds like the ones you've got could be an unbranded version.
    Answer by: Chris Horridge (Admin) on 14 Aug 2023, 08:13
    When I dim these will the colour get warmer as they dim, or stay the same?
    Question by: sonya mcgilchrist on 11 Nov 2023, 22:10
    The 2700K version of this lamp gets warmer as it dims.
    Answer by: Mathew Smith (Admin) on 13 Nov 2023, 08:29
    Do these LEDs strobe at 100Hz?
    Question by: John Joseph Shanley on 11 Feb 2024, 19:29
    These are made to operate at 50/60hz
