Our kitchen is currently lit with 10 × 50 watt tungsten lamps. Yes: that's a total of 500 watts. Which is utterly obscene and I feel distinctly uncomfortable just thinking about it. We want to replace these tungstens with LEDs, hence reducing the power required to light the kitchen by a factor of 10 or so. We have several requirements:
- Must be dimmable down to 5% or 1% (some LEDs only dim to 60%)
- Must produce enough light to fill the kitchen
- Must produce a warm, cosy light
- Must produce a light with a high enough colour rendering index to mean that skin looks like skin and not like pale plastic
This post is basically a collection of notes recording my research into dimmable LEDs.
