Sorry for late reply. Yes I've learnt that there is not really an ideal with lighting and it's somewhat personal preference, but I think it is important to have the right lumen output for the space you are in.
I decided on a Phillips 12W LED 3000k 1400 lumen bulb to replace a 100W incandescent. 3000k is a tad whiter than the 2700k incandescent which I don't mind but 1400 lumen seems a bit bright for the space it's in. I've heard about a Phillips Scene switch LED bulb that can be dimmed to three different levels from a standard light switch which could be interesting. They are an 800 lumen 2700k bulb which may be more suitable for me.
