Few people can have escaped noticing that conventional incandescent lighting is rapidly being phased out and that the preferred (over Compact Fluorescent Lamps) alternative is LED, which is widely regarded as the way forward to a environmentally friendly, low cost lighting future. The question though is: where to start?

Well you could simply rush out and buy LED replacements for every light bulb you presently own but I wouldn’t advise it. First of all it would be really quite expensive, but also the odds of getting things badly wrong with this approach are quite considerable.

Getting to grips with LED lighting doesn’t happen overnight - this is a completely different technology to incandescent lighting and requires a bit of getting used to before you can get it just right for your own needs. But stick with it and the end result is superior quality lighting that also happens to save massively on electricity costs.

Accordingly, you ought to pick a location that you planned on refurbishing anyway or that otherwise uses a great deal of lighting (either lots of lights, or lights left on a lot). The likelihood that you will quickly notice a difference in operating costs (and also light quality of course) will be thus enhanced.

Getting off to a successful start this way is important since it provides the encouragement to proceed with further steps towards finally replacing all your incandescent lighting with LED. The room that most people nominate to start with is, unsurprisingly, the kitchen. This usually has many lights that also get used a lot and a kitchen lighting makeover invariably seems to appeal.

The average modern kitchen tends to feature a sizeable collection of halogen spot lights (typically either recessed or set on tracks). The amount of electricity that these literally burn is quite extraordinary, yet replacing them with LED lamps that consume a fraction of the energy is no more complicated than pulling out the old halogen and pushing an LED back in its place. At least for GU10 LED lamps it is - for the low-voltage MR16 format you should also replace the existing 12v transformers with one or more LED drivers.

The same holds true for concealed lighting tucked under, above or inside cabinets as these too can be replaced with LED strips or mini spots. This is also a great opportunity to add lighting whilst you’re at it since LED strip lighting is easy to install, lightweight, and is packaged in a variety of forms that can be trimmed or joined as required. LED lighting to accent covings, plinths and set into kickboards to illuminate the floor are all popular techniques.

Three key considerations should be borne in mind with regard to LED lighting.

1. Quality. It’s true that in general quality costs more but with LED quality counts for everything; so be prepared to pay a premium and avoid the path that leads to false economies and disappointment with cheap products. Look for recognised brand names such as Sharp Zenigata or anything using Cree LED technology. Remember, incandescent light bulbs are also cheap and yet they cost vastly more in running costs over time.

2. True cost. Or what is known as TCO (total cost of ownership). Over a period of 50,000 hours a single LED will incur zero replacement costs and cost as much to run as it costs to buy. Over the same span a halogen lamp will need to be replaced at least 25 times and is likely to incur 1,000 times its purchase price in electricity costs. Even if an LED costs 20 times more (and many do) it’s cheaper just on replacement costs alone and orders of magnitude cheaper on electricity costs.

3. Usage. An issue many people have with LED light is that it can be both blindingly bright yet unable to project luminosity over distance. An easy way around this is to direct the lighting away from direct line of sight and reflect it off walls, floors, ceilings and features in the room. The obviously accents interesting aspects in the space with the added benefit that it also produces a softer light that does then spread out well. It does however require more individual light units to create this effect than if using conventional incandescent general lighting.
