The ~20W CFL for our landing light died. I temporarily put in a 7W (~420lm) LED lamp replacement, but it clearly wasn't going to be bright enough.

So I bought the brightest B22 bayonet LED lamp that Clas Ohlson in Kingston had to offer, which is this interesting frosted beast consisting of eight separate yellowy-orange LED filaments. Presumably this construction allows for a illumination pattern closer to a tungsten GLS bulb rather than a more typical LED point source or three. This also claims a colour rendering index (Ra) of 90.

There was no non-dimmable lamp in Clas Ohlson at this output power (10W, 1055lm, ~75W incandescent equivalent). Normally I avoid dimmables because I assume that the extra electronics makes them more expensive and more fragile. Although we don't dim the hall light, this lamp has a pleasant soft-start feature and comes to full brightness over a short time (though under 1s to 60% according to the spec), which can be easier on the eyes in the dark!

The claimed efficacy of over 100lm/W is impressive. The LEDON managed a mere 60lm/W about seven years ago! The LEDON was a premium product; this unit, product 18-1454, was £7.99.

Clas Ohlson offers a two year guarantee, but suggests a 15,000h life which may be good for 15 years.
