Mine was – they accept the issue but do not as yet have a resolution. Not cool for £50 a pop bulbs.
As a matter of interest I went to Argos and bought the old (longer barrelled and no bluetooth) mode for a laugh/loan. They did NOT have the issue, but I couldn’t mix and match as the colour output is not the same (green on new model is far better than old model for example).
Anyhow I digress. The long and short is no – they will offer refund to me (not quite sure how that would work with me buying from another store) or defer till they fixed. I gave them a few weeks to determine if they could fix it since I love the bulbs, just not the weeeeeeeeeeeen. WIP.
It would be good for all who read this to raise a case with Philips. I would suggest to call; the bonus is their support team is actually (IMHO) quite good / responsive. People power …
Keep us posted?
p.s I still suggest you raise a case, but can you not swap the GU10 from hall to bedroom? Workaround?
