How To Benefit From LED Lighting In Your Kitchen

By Abigail Monot

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.

Clearly, a major problem with central ceiling roses in a kitchen is that they create dark spots and you are always casting your own shadow onto worktops. A popular solution is to fit a number of halogen down lights in a pattern in the ceiling to produce uniform general light and install extra lighting specifically for worktops and hobs etc.

This does indeed work quite well, but brings its own set of problem: halogen lamps run at very high temperatures; they don't last well; and they are pretty much the most expensive possible way to light a kitchen. Over ninety percent of the cost of incandescent lighting in general (and halogen lamps in particular) is the electricity they consume.

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 have become accustomed to rating brightness by wattage, but the rated wattage for an LED light bulb should be about 10% that of the equivalent normal incandescent or halogen bulb. So expect to replace a 35w halogen lamp with an LED rated 3w or greater, 50w requires a 5w LED and so on.

How cool or warm a light appears is graded according to "color temperature". LED lights come in a wide range of white color temperatures (not to mention actual "colors"), but historically it was easier to manufacture blue LEDs and hence many cheap LEDs exhibit a cold/bluish tint. However, if you specify warm white (technically a temperature below 3,500 Kelvins) you should get a fair approximation of the white light normally created by halogen lamps.

A narrow beam angle, say 45 degrees, makes any light appear tighter and more contained to a defined spot, whereas a much wider 120 degrees spreads the light out evenly, eliminating glare and "hot-spots". Quite possibly the best LED spot light currently available that acts as a straightforward halogen replacement is the Sharp Zenigata.

One of the key factors to how any artificial light appears is not so much the light itself as the surface it shines on. To warm things up, point spot lighting at warmly colored areas (terracotta tiles, natural wood or simply a warmly painted wall). Alternatively, create dramatic effects by for example directing blue LEDs at fairly dark surfaces - blue LEDs reflected off blue, green, granite and steel can look stunning.

Mixing a variety of lights that offer different characteristics with a range of textures and colors makes it possible to obtain an extensive palette of effects for the various zones in your kitchen. LED strip lighting systems in particular offer all manner of options for accenting plinths, coving, worktops and pretty much anything else you could imagine. But at the end of the day though, once you're done playing with all the new ideas on offer, try and settle on just a few designs that really appeal - it's quite surprising how impressive even a bit of LED kitchen lighting appears.
