LED technology is hugely dynamic and changing all the time. We use a lot of LEDs for accent lighting or for garden lighting where a little light goes a long way. Most of the LEDs that we use are high quality warm white varieties with good colour rendering so that, for example, light is skimming across an oak floor the colour of the oak is enhanced rather than killed off.
We also use very warm white, almost candle coloured versions for a particularly warm glow, e.g. around the foot of a bath or back lighting shelves. The fitting itself is selected for its size, aesthetics, glare, and effect.
LEDs as a primary light source is still a very expensive and not very flexible option, but the technology is advancing all the time.
