You might get version one, you might get version 2? I'll wait until I know what I'm getting, thanks.
Also why the E27 - I thought every home in the UK used bayonet (BC) fittings in the ceiling rose?

Not every home. I have E27's throughout my house.

Because most of the world uses E27, so they want to sell everywhere, not in the UK only. Adaptors available, 2 for £1 at IKEA.
Got E27 all round the house.
Has anyone got these yet?
I got a hue one from the 4.99 deal yesterday and it's pretty cool but at that price for just white and one for account. Full price is bit silly.
so wondering how good these ones are so I can grab some. Anyone got experience, feedback?
I've had one of these for I guess 2 years now - must be the R1 version. Not very bright - would not buy another R1.
E27 is more dangerous than BC as the metal screw part is at mains voltage so there is a higher risk of shock when removing/fitting. The BC only has live part at the base making it mechanically impossible to get a shock!
I guess in a home environment it down to personal choice... (ES can work loose given enough vibration, but I don't think that's relevant in a home environment)
Warning. These lights are not very bright. The colours are especially dim. Fine for some use cases like a lamp for mood lighting. Personally I would just buy innr bulbs and use with the hue ecosystem.

If I am not mistaken, Innr bulbs are priced close to Hue?

Correct. The white and warm white bulbs are better value. If you want colour it costs. Buy cheap buy twice.

B22 needs to die. (IMHO :))
The availabiltiy of B22 bulbs, fitments etc in UK is lower now than E27 thanks to Ikea (and many others) stocking only E27.
Keeping two (legal) standards in UK fragments the market and raises prices (although mostly for B22 I htink).
I am replacing (over time) all fittings in my home with E27 since all new technologies will definitely be available in E27, but only "might" be available in B22.

interesting point re safety, but tbh these are both legal standards in UK.
These are not illegal imports from perspective of the mechanical fitting (whether the bulbs are "safe" is another discussion :P)

I'm very wary getting random brands of smart bulb now. There are plenty of cheap alternatives to hue, but the ones I've tried have really terrible colour on their white light. It's hard finding a setting that matches a soft or warm white setting that isn't tinted completely wrong, if you can at all
Can anyone recommend a smart Bulb holder instead?
Also any feedback on eWeLink app, as lot of Chinese products seem to be using it

Try this, but there are more out there.
Personally I wouldn't hook up potentially dodgy Chinese electronics to my home wi-fi network. Smart home/IoT devices are constantly having security vulnerabilities made public, if they have any security in place at all.
I use these (bayonet and screw variants). Pretty bright, and decent colours. Work well with Alexa and through their own app.

Good price voted hot but these can't be compared to Hue. Setup can be a pain and reliability is patchy.

I'd pay extra for Hue always. Just works.

Have a look and invest on a VLAN for your IoT devices. Well worth the price you pay for the set up given how many things are connected to the internet these days.
I have an smart dimmer switch which uses ewelink. Works well via app and Alexa. However, ewelink app does not have option to create a schedule time to switch on at specified brightness... A bit dim from them.

I tried ifttt but somehow it lists all other ewelink devices except the dimmer switch...
If you're ordering from Ali Express I would go for a yeelight instead. They're a couple of pounds more expensive but much brighter and the app is excellent.

I have 14 sonoff devices wired at home and use both the ewelink app (Android version) and Google assistant wether I'm at home, away or driving (hands free voice control) , the app does the job no problem plus there's IFTTT integration, I did find earlier this week that Google stopped connecting to eWelink (or 'Smart EW link' as it was named in Google accounts) which meant I couldn't control anything via the Google assistant but managed to resolve this by removing the 'Smart EW link' linked service, and adding what's now called 'eWeLink Smart Home' and hey presto after reasigning things into their relevant rooms it all works again, problem solved. Thanks eWe and Google as I couldn't find a resolve online anywhere and just stumbled over the fix. I would recommend the Sonoff stuff I've been using it now in various applications for about 2 years without an issue apart from that above.
Yeelights. Get them
Not for me. Randomly getting old or new?

That's a lot of incorrect information!
First there is NO law that dictates what light fittings are to be used in the UK - there are regulations & guidelines, but no law.
Second E27 is not a universal fitting either - there is no legal reason to have 2 standards in the UK, it's just what is popular.
Also worth noting that most US homes use E26...
Regards the screw on an E27 being live, get the wires to the holder reversed by someone competent,problen solved, I've bought many items in the E27(Edison 27mm diameter)(E26 26mm)from wherever and have many adaptors to convert to B22, in my kitchen I have radar lightbulbs that transmit a 5.8 ghz radio signal that upon sensing movement cause the bulb to light, in B22....not a chance,I also have PIR led bulbs on the landing ,also E27,ultimate hands free illumination as I do in the kitchen.

I think you misunderstood my message - I was simply noting that both B22 and E27 are legal.
IMO, since E27 is more widely available, and has more options, it should become the default and B22 should be phased out.

I have some E26 devices also and to all intents and purposes they are interchangable with E27.
In fact the E26 I have (hue bulbs) measure the the same as E27 hue with micrometer.

No - there is no such thing as a "legal" light fitting?
Also I think you'll find that E26 is more widely available, although it does depend on what your definition of "widely" is...
(~300M homes in USA vs ~50M in the UK)
Do share with the group your evidence as to why B22 should be phased out & where you get the stats to show E27 is more widely available. Also E26 & E27 bulbs & sockets may appear interchangeable, however they are different by design for safety (the E27 uses a deeper socket & longer thread - if you use the longer bulb thread in the shorter socket you expose the mains voltage. Consider the dangers of that in a table lamp...)
Go do some research before posting your opinions...

1) Legal vs "meets regulations" - agree w you
2) E26 vs E27 - also agree. But in UK (this is hotukdeals, right?) I have found E26 to work safely in a UK E27 fitting. I woundnt try the opposite...
3) Widely available - again this is hotukdeals so I would be discussing the availability in UK, not america which uses E26. This is based on my own personal experience, but I am sure we can find some anecdotale "evidence" too. Standard "white" bulbs no problem either way and its not a consideration. Want something more specialised/unique (smart bulbs, decortative bulbs etc) then E27 is the most common since smaller manufaturers dont bother to make both.

But to "do my research" and "show my stats", lets look at the availability of BC/B22 vs SES/E27 at some common UK vendors of bulbs:

habitat.co.uk/lig…lbs - only sells E27
heals.com/lig…tml - only sells E27
ikea.com/gb/…44/ - vastly more E27
johnlewis.com/bro…rim - nearly 2x more e27
diy.com/lan…bs/ - 66 BC vs 127 E27
screwfix.com/c/e…001 - 2x more SES vs BC
...
...

Hence why I am changing my fittings, slowly over time, from bayonet to E27.

Maybe having worked in Electronic manufacturing for 30+ years you could help me understand, I guess up until now I've just been good at convincing my employers that I do. UK,Australia and a few others don't use E27 but most of the rest of the world do so manufacturers will tool up for the largest market.

In reference to the first comment: "Regards the screw on an E27 being live, get the wires to the holder reversed by someone competent,problen solved,"
We are talking AC voltage here - how would reversing the wires solve the problem? The voltage swaps polarity 50 times a second in the UK?


With 30+ years experience I would expect you to know the reason for the evolution. (What standard do you comply with?) E27 was designed to allow the use of incandescent bulbs on 240v AC using similar but slightly different screws. This was to prevent the use of E26 bulbs in 240v sockets (yes you may be able to screw them in, however if they followed spec you wouldn't be able to screw them in completely and complete a circuit). Over the last 30 years incandescent bulbs have been replaced with different technologies. A consequence of this means that the bulbs can now operate across a much wider voltage range therefore negating the mechanical safety measures previously designed.
It should be noted several design flaws exist with the screw design, which are not present in the Bayonet style. Screw types can suffer "weld in" which cause the screw thread to lock making removal difficult and dangerous (as you could break the bulb).
I could (& have - you can search for it online) write up a paper explaining the mechanical advantages of the Bayonet vs the screw type fittings, however this is HotUKDeals...

Ahhh these comments make me smile, some very informative and correct and some very slightly off, I too have had some 30+ years in the electrical and electronics industry in a wide ranging spectrum too, and it's evident that I wouldn't be making such a good living out of the industry if everybody had the same knowledge and understanding as I and I suspect some others have on here too, you know who you are, my employer has an annual turnover of some £50m over the last 12 months and we are around 200 strong and profitable too I have dealings with things from 33,000 volts AC down to millivolts AC and DC.

So back to what has turned into a debatable subject between ES (Edison Screw, called this as Thomas Edison was the inventor) and BC (bayonet cap). And I'll point to some online resources.

Firstly
The inventor of the Bayonet cap fitting which may give some understanding as to why there are generally two types around, neither in particular right or wrong

calex.nl/en/…ng/

Secondly
A bit of an explanation as to why we (currently) have an AC distribution system not only in the UK but pretty much worldwide so in the late 19th century Nikola Tesla defeated Thomas Edison in the AC/DC battle of electric current.

cosmosmagazine.com/tec…ack

Thirdly
Winding back slightly in Edison's (DC) attempt to win the battle with Tesla (AC) some pretty horrific demonstrations were done using AC by Edison to dis-credit Tesla, particularly this in 1903

wired.com/200…amp

Pretty shocking!!! So moral to all this is...

If you don't know what you're doing with electrics, if you're not confident AND competent then it's better you leave it alone and pay a professional to do the work for you.

The guidance as to where electrical work stands in relation to the law can be found on the NICEIC (national inspection council for electrical installation contractors) website

niceic.com/fin…ork

Oh and in my experience Edison screw ES27 (27mm) or ES26 (26mm) actually tend to loosen over time the only time they jam and then break when trying to get them out is when they have actually been over tightened by someone that has got a bit over zealous when fitting or re-fitting. Bayonet cap can stick too particularly when the sprung contacts tend to sieze up.

Some UK homes also have lighting pendants with that are not BC or ES but are only compatible with compact fluorescent fittings, I saw these used cira 2006-2009 to meet some energy saving requirements at the time for new build properties, I would expect most people have had these pendants replaced by now as LED are generally much more efficient than compact fluorescent fittings.

That's me for now, I hope at least the slightest bit of info might help someone, back to work tomorrow when I actually get paid a ridiculous amount for this dribble. ?
