I purchased Philips Hue White and Color Ambiance BR30 60W Equivalent Dimmable LED Smart Flood Light (Newest Model Compatible with Amazon Alexa Apple HomeKit and Google Assistant) (Certified Refurbished) from Amazon in November 2018. This is a refurbished hue floodlight from Amazon. I shipped it from US to Singapore via amazon prime. I was informed that even though the bulb was 120V it works with Singapore’s 220-240V bulb fittings. Note that I have numerous Hue bulbs and lamps all over my house in Singapore without any issues (I bought Philips 464487 Hue White and Color Ambiance A19 60W Equivalent Dimmable LED Smart Bulb previously from Amazon which is also 120V without any issues), but this one particular bulb is causing problems. The main problem is after switching on the bulb for some time, if I were to use the app or dimmer switch to switch it off, the bulb will come back on immediately automatically after 1 second. I’ve disconnected the dimmer switch and used the app and it still has the same problem.
I noticed on the forums and online that many people have this same issue. It could be a hardware or software issue or the fact that it’s 120V on a 240V fitting. I do not have any other lighting app running in the background and I disconnected homekit from my hue bulbs just in case those were causing the bulbs to come back on. I’ve updated all software for bridge and bulbs, I’ve resetted all bulbs rooms and accessories, I’ve cleaned up the bridge, I’m not using an enclosed bulb fitting, I’ve reconnected the bulbs, I’ve changed the channel for the bridge, and all no no avail.
I also noticed that this issue only happens when the bulb is switched on for some time (meaning the bulb may be heated up). If I only switch on the bulb momentarily and then switch it off, it remains off. If I switch the bulb on for a long time like 2 hours plus, then switch it off, it comes back on immediately.
Please assist me. I am not sure if this is a widespread hardware problem since so many people face it, or it’s a software bug that can be fixed with a software update or I have a faulty refurbished product
