I doubt I will buy anything but LED now as I have spares for most of the house, all of a standard that gives good illumination, so must use those up before buying more.

Stumbled across these Diall branded filament style LED bulbs on sale for £5 in B&Q the other night and liked that they are not nearly so heavy as the Osram LED I bought a year or so ago, whose heatsink proved too weighty for that bulb to be used in my anglepoise lamp!

http://www.diy.com/departments/diall-b22-6w-led-filament-classic-light-bulb/1326894_BQ.prd

So purchased one of these to see how it compares to the other LEDs I’ve got at home and whilst it does provide a bright (810 lumen claimed) omnidirectional light, the colour temperature (which is supposed to be 2700K) is decidedly on the yellow side

Is this typical with filament LED bulbs?

As I’ve got one of these Philips LED globes in the living room which provides a much nicer “warm white” at 2700K.

Buy the Philips LED Globe 8718291717041 Globe

However I can’t find anywhere which has Philips (or Osram) filament LEDs in stock, so wondering if anyone can recommend a classic B22 bulb that provides around 800 lumens of warm to natural light (up to 4000k) with a wide angle beam...

It is now possible to get 230 v AC LEDs in any form factor. So transformers are not necessary. Dimmable LEDs are another story.  Traditional dimmer switches either do not work or work very poorly with LEDs, even those listed as dimmable.  The fundamental technology and drive requirements are very different.  The only successful dimmers for LEDs is one where the controller converts the current into a DC one and then switches the current using pulse width modulation. So you need to replace the entire string from wall fitting, probably transformer and then probably low voltage LEDs.

Thanks @dannnielll. Since posting the query I’ve changed most of the lights. Went with non dimmable G9’s and Philips Hue for the ceiling GU10’s. only ones I haven’t changed are the under counter ones.

I replaced all my bulbs   with LED ones and even found them brighter than new fluorescent ones e.g. if the LED and Fluorescent said they were equivalent to     60w normal bulbs the LED was a lot brighter. I also notice the cool are also brighter than the warm. The cool giving a white light and the warm a yellow.   
Funny I have two outside lights connected to a sensor and when using LED in them it would not work but will work with just one LED and a normal.        

I got mine at Screwfix @£8.99 for 5.
