It is really important to understand that all modern light sources are generally very good. The bad old days of flickering fluorescents and harsh LEDs can be put well and truly behind us if you use quality products and research the technology a little beforehand. Besides which, with Part L of the building regulations in force, you will have to engage with these technologies. Fluorescent, when used in an appropriate way is a really effective light source and can generate some surprisingly subtle lighting effects. It is also dimmable, and with good quality equipment, down to quite low levels. We always use fluorescent as an indirect light source: in a cove or coffer detail, or behind a diffuser material of some kind. We’ve all seen shockingly bad LED lighting, usually retrofitted, but LED can be specified in confidence if you work with a quality manufacturer or supplier who can advise you on output, colour temperature (warm or cool), and crucially, colour rendition: how accurately the particular LEDs represent colours.
A key piece of knowledge here is CRI – (Colour Rendering Index). Don’t even consider LEDs with a CRI of less than 80. A CRI of 85+ is good, and 90+ is very good.
