It's not hard to see how the numbers scale up; taking the USA as an example, we know that each kilowatt hour (kWh) of electricity that is generated results in 1.34 pounds of CO2. A fairly typical kitchen might easily have 10 x 50 watt
halogen lamps used for say 10 hours each day. This works out at 0.5 kWh * 10 * 365 * 1.34 = 2,446 pounds of CO2 per year.
Now see what happens by installing LED kitchen lighting, replacing 50W
halogen lamps with 6W LED equivalents: 0.06 kWh * 10 * 365 * 1.34 = ...

Halogen lamps with 6W LED equivalents: 0.06 kWh * 10 * 365 * 1.34 = 293 pounds of CO2. Extrapolating this, you can, in ...
And it’s even easier than that, because there is a surprisingly small range of values that good domestic LED light bulbs conform to.
Let’s take the most pervasive form; the LED spotlight. People invariably purchase these as low energy (hence low running cost) replacements for
halogen lamps rated at either 35 or 50 watts. Now most folk understand instinctively how bright these types of
halogen lamps are and can easily tell you whether an apparently equivalent LED is more or ...

Halogen lamps rated at either 35 or 50 watts. Now most folk understand instinctively how bright these types of
Halogen lamps are and can easily tell you whether an apparently equivalent LED is more or less the same the level of brightness. So how many watts of LED do you in fact need?
Well it turns out that an LED rated at 6W will pretty much match a 50W
Halogen, while one ...
However, while all these different types of lighting really do help create a stunning look that is both immensely practical and visually pleasing at the same time, there is a price to pay and that is the cost of running it all.
Up until quite recently it was common to use 50W
halogen lamps for recessed down lighting. In even a fairly modest with say 10 lamps that's 500 watts just to provide the background light. You can easily see how a well appointed kitchen might be consuming thousands of watts, and with the price of electricity where it is today, that's not exactly small beer in terms of the financial ...

The fittings themselves are usually agnostic on this score and you typically have a choice between different types of light bulb, namely mains versus low voltage (often characterized, incorrectly, as GU10 and MR16) and incandescent (typically
halogen) versus LED spotlights.
If you're determined to go down the conventional incandescent lamp route then you may now proceed to the debate about low voltage compared to line voltage. If however you don't have numerous screws loose and are ...

Halogen) versus LED spotlights.
If you're determined to go down the conventional incandescent lamp route then you may now proceed to the debate about low voltage compared to line voltage. If however you don't have numerous screws loose and are instead intent on saving yourself a great deal of money by opting for LED then you don't need to concern ...
Actually, why does anyone buy 1W and 2W LED bulbs anyway? To replace their kitchen down lights with night lights perhaps?
Still on the printed information, check also for color temperature (and for spot lights, the beam angle which you want to be about the same as for a regular
halogen lamps). The color temperature is not something anyone ever mentioned with incandescent light bulbs, but with LED it is important since there is quite a wide range.
We're talking about white light "color" as in how warm or cool the effect is. As a rule, for ...
... Don't expect a 1 or 2 watt LED to replace it - it's just not possible. Actually, why does anyone buy 1W and 2W LED bulbs anyway? To replace their kitchen down lights with night lights perhaps?
