Unlike traditional light sources, which are large and bulky and can get hot, the latest technology allows shelves to be back-lit, halo-lit or front-lit by discreetly incorporating thin LED lighting strips. The best 1W LED uplights are now small enough to be easily recessed into standard-depth floors, steps and skirting-boards. And with their very long life of up to 15 years, maintenance is minimal. Choose an LED fitting with a relatively narrow 8° beam width to create a dramatic effect. The key when selecting LED lights is to ensure the colour of the light they produce is not too 'cool. Always ask for 2,700K. Further considerations are the clarity and colour rendition of the LED, shown as CRI (Colour Rendition Index). This is the measure of the true colour of what is displayed - above 90 is best and below 80 to be avoided. This is particularly important when using LED downlights to illuminate pictures, as you want the colour to be as true as possible. Next week: Magnus Englund, Skandium
