How To Easily Move To LED Lighting

Most people are by now aware that traditional incandescent light bulbs are fast becoming a thing of the past and that LED (rather than CFL) alternatives represent the future of low-energy, low-cost, low-environmental impact lighting. But where to begin?
One option might be to purchase LED equivalent bulbs for all the various lights you currently have but I would caution against that approach. Not only would it turn out to a rather expensive exercise, but you it also greatly increases your chances of having the end result turn out rather badly.
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.
Sound advice then is to begin with an area that either uses a lot of lighting or has the lighting switched on a lot (or simply somewhere you would like to refurbish anyway). In this way, your chances of seeing a noticeable difference with respect to both light quality and running costs are greatly increased.
It’s important to get off to a good start in this way as it will encourage you to then take another step further towards the final goal of switching totally from incandescent to LED. For many, if not most, people then it is the kitchen that invariably matches these criteria - it typically has a lot of lights that get used a lot and refurbishing the lighting provides a relatively cheap makeover.
The typical modern kitchen often uses quite a number of halogen lamps, either mounted on tracks or recessed into the ceiling. These waste a phenomenal amount of electricity as heat and are simplicity itself to replace with retrofit LED equivalents. Just pull the halogen lamp out and push in an LED rated to produce the same level of light. For GU10 LED bulbs that’s it, but for MR16 low-voltage lamps you should also purchase an LED driver to replace the 12v transformers previously used.
The same idea (straightforward replacement) also applies to lights installed atop, underneath and inside wall cabinets. Alternatively, add some lighting to these areas if none already exists since LED strip and miniature spot lights are simple to fit, being both light in weight and flexible with respect to being cut or connected to suit any configuration. A common technique is to accent plinths and covings, or if fitted to a kick board to pick out the floor.
Three key considerations should be borne in mind with regard to LED lighting.
1. Quality counts. It’s only natural to count the cost but what really counts with LED lighting is quality and the two are mostly related. Cheap products may look like a bargain but they won’t perform as well or produce the savings you should expect (recall that incandescent bulbs cost little to buy but ultimately represent a terrible waste of money when you calculate the true “cost of ownership”). Look out for respected brands such as Sharp’s Zenigata or the Cree Evolux.
2. Cost. The real cost of lighting is the price of the bulb(s) plus the cost of the electricity. Over say 50,000 hours, a regular 50 watt halogen bulb will need to be replaced 25 times and cost 1,000 times the price of the bulb in electricity. An equivalent LED will require no replacement and cost much the same to run over all that time as it costs to buy. So over 50,000 hours the true cost of a $20 LED is likely to work out at (20 + 20) $40 and that of a $1 halogen at ((1 * 25) + (1 * 1000)) $1025.
3. Usage. LED lighting is most effective if you use multiple light sources of varying intensity and color ranges. Although very bright, they tend not to project light as far as incandescent lights do, so one of the most common ways to resolve these characteristics is to simply reflect the light off a nearby surface. This produces a diffuse light that fills the space and neatly kills two birds with one stone.
