Great kitchen lighting design typically utilises a large amount of lighting (which means more than just installing a few extra ceiling roses). Kitchen lighting needs a variety of types of lighting for different areas and purposes. The absolutely worst way to illuminate a kitchen is using bright fluorescent ceiling strip lights. They're certainly very bright - but also flat, cold and guaranteed to give you a headache into the bargain.
The most obvious issue with having central ceiling-rose fittings in a kitchen is that they produce dark spots, most noticeably where you cast your own shadow onto work surfaces. A solution seen in many kitchens involves fitting halogen down lamps in a uniform pattern across the ceiling then adding task-specific lighting for workareas, hobs and so on.
This solution works reasonably well, but does have its own downsides: halogen lamps operate at extremely high temperatures, don't last very long, and are without rival as the most expensive means of lighting a kitchen. Some 90% of the cost of incandescent lighting (of which halogen is an extreme example) is the electricity they use.
This one fact helps explain the growing popularity of cool, super energy efficient LED kitchen lights. For mains powered lighting you simply replace all existing GU10 halogen lamps with equivalent GU10 LED lights. For low voltage systems, you first replace existing 12 volt transformers with a smaller number of constant voltage 12 volt LED drivers (each can power a number of light fittings) then replace MR16 halogens with LED light bulbs.
There are 3 principal qualities to consider when evaluating LED spotlights, namely: luminosity (or brightness); color temperature (how blue and cool or yellow and warm the light seems); and light beam angle. Try to obtain as good a match as possible to the performance of your halogen lamps in these 3 areas.
We are used to measuring brightness in terms of wattage, but an LED light bulb will have a wattage rating at least ten percent that of it's equivalent incandescent or halogen bulb. Therefore, when replacing a 35w halogen lamp use an LED of 3w or above, and likewise replace a 50w with a 5w LED, etc.
Color temperature is used to measure how warm or cool a light seems. LED lights are available in a variety of white color temperatures (and also, colors) but since it has always been easier to manufacture blue LEDs, many cheap LEDs tend to have a cold/bluish tinge. Go for warm white (color temperatures below 3500K) for a reasonable approximation to the kind of white light normally associated with halogen lamps.
The more focused the beam angle is (i.e. 45 degrees) the more the light will appear tightly constrained to a single spot-like area; conversely wide angles (i.e. 120 degrees) disperse the light uniformly and reduce hot spots and glare. When looking for a good LED replacement for regular halogen lamps, the Sharp Zenigata LED spotlight is perhaps the top contender at present.
Determining how artificial light appears to the eye often owes less to the light itself than to the surface it is aimed at. A warm feeling is easily obtained by pointing spot lighting at areas that are themselves warmly colored, such as terracotta tiling, any type of wood or even just a warmly painted wall. By contrast, a dramatic effect can be had by simply throwing blue LED light against dark or hard surfaces - blue or green tiles, granite, enamel and steel all lend themselves to this treatment.
Combine LED lights of varying characteristics with different textures and colours to produce a range of effects suited to individual zones in your kitchen. The are almost boundless possibilities, even before you get to playing with LED strip lighting to accent plinths, worktops, coving and more or less anything else that takes your fancy. As ever though, the best designs often emerge by limiting things to a handful or less of the most appealing ideas - but don't be surprised how stunning even small amount of LED kitchen lighting looks.
