Yeah it was mobile , this should work ....

Duracell 4W(30W) LED GU10 Lightbulb- Single pack | Light Bulbs | ASDA direct

They are a quid cheaper here: lightswitch.co.uk - product page
Can't find any reviews at the moment.   If you decide to get them, I'd like to hear what you think.
They are more attractive, I think, than most of the GU10 LEDs where you can see the actual LED element.

I am going by the logic that such a big company wouldn't put their good name to shame by selling rubbish , my faith could as always be misplaced but we shall see when I get some fitted .....

Pay attention to the kelvin rating, 2700 is kinda yellow.  For commercial use where you need accurate colour go for 4000-5000k. Otherwise that yellow light will make the hairdo look more yellow than it is.

I've been looking to try and replace the bulb used in a freestanding lamp we have in our living room, currently it uses the following bulb

Philips 20w E27 Screw Cap Low Energy GLS Equivalent to 86w: Amazon.co.uk: Lighting

looking this one up I see that its output is around the 1100 lumens marks so i'm trying to find an equivalent in LED, any suggestions as I am struggling to find the right one!

Hi JimmyMac,

I think you may find 1100 lumens on this page:
Daylight LED Bulbs

You will find these great for reading as they are 6000k daylight, find something yellower by clicking on LED GLS.
I have used this firm for my CFL bulbs for the whole house

Thanks, I would like it to be a yellower light really so looking at more warm white than daylight. We may have a different solution now anyway. I think we need a second lamp in the room, then we should be able to use two bulbs with a lower lumen to give us the light we need.

Thanks for the link to the site though, will likely order bulbs from there

While not the exact same lamp as linked to, I have bought (now) 4 packs of 3 Duraclell GU10 frosted warm white led spots from my local ASDA (@ £10 per pack).   The spec says 3.8W (->35W equivalent), 3000K,  36 degree ( /-18) beam angle, 250 lumen, Ra CRI of >80, 25,000 hrs, ca. 40,000 on/off switching operations, non-dimmable.

Using them in the kitchen, initially in a couple of in-ceiling downlights (GU10 CFLs) over a worktop to trial and now replacing 6 x 50W halogens on a 'bar' [admittedly these are over 6 years old so perhaps I won't get a super-quick payback, but will be more inclined to leave them on (and my head doesn't get fried by the halogens any more if I stand in the wrong place ) as I was always concious of the 300W burning].

I'm quite pleased with them, they are little more 'spotty' than the halogens they replace and a fair bit colder in light (halogens @240V ought to be nearer 3200K than 2800K, so I'm unsure if the 3000K claimed is correct?).  The lower lumen output of these leds vs 50W halogen is not an issue in my kitchen.  You can 'see' the three leds but they are slightly diffused.  They make the tungsten cooker hood lamps seem very yellow, and similarly the two under-cupboard T4 fluorescents that I'd like to replace next (before the tubes fail yet again) if I can find something suitable in led strips (perhaps)??   The colour rendering is (just) acceptable to my eyes, but I am a bit finicky (and one reason I've avoided leds up until recently).

Asda had some ses candle Duracell lamps in a '3 for £10 pack' that would fit my cooker hood, but they are 2700K rather than 3000K so not sure if they'll match (colour-wise).

BTW the white surround of the lamp does look quite good in the fittings we have as it is 'on show'... but only time will tell if it gets covered in cooking grease and can't be cleaned easily.

At only £3.33 each these are pretty good value for money, in my opinion.

Quick question, do the warm white LED bulbs give the kind of yellow glow you get from halogens? I picked up what was labeled as a warm white LED today and it seems to be as clean white as the ones in my kitchen. I want to be able to replace the bulb in the tall lamp in my lounge with an LED and still have that warm glow

Tricky, I prefer cool white so have no warm white Led to compare.  I think you may find that Warm white led is not quite as yellow as the other bulbs.  Also if you can directly compare them to your kitchen ones you may find them mislabeled or miss packaged. If you look at it and its package does it look correct.  In photography they talk about white balance and these are settings sometimes used:

TungstenWarm FluorescentCool FluorescentDaylightCloudyShadeetc.
So I guess there may be a difference, and you may never get a tungsten shade of LED.

Another line would be to find the specification for your cool and warm white LEDs.  Good luck.
