Green Lighting

LED lighting was featured on the Afternoon Show in Ireland last week. Apparantly it takes up much less energy than normal light bulbs and gives off a nicer light than normal environmental light bulbs. - see http://www.rte.ie/tv/theafternoonshow/story/1092169.html

The feature focussed on how green the product was. But does anyone know if these types of lightbulb are worth buying from a moneysaving point of view? I.e. does the added expense of buying the bulbs get paid back with the energy savings.

it all depends on the wattage,not the colour,
a 20 w blue lamp will use the same energy as a 20w green lamp...well i hope so!

Sorry, I meant "green" in the "environmentally friendly" sense of the word. Apparently white LEDs are now available that plug into normal light sockets and use less energy and are therefore more environmentally friendly. They are not just one LED but lots stuck together.

They obviously cost less to run because they use less energy. But expext that they cost a lot more than normal light bulbs for the same light output.

Have tried these lights in display cabinets etc but the light output is poor even with 12 led lamps. Don`t think you gets lamps with more LED`s in them .

Think this may well be the future, but I'm happy to give it a little while to sort itself out.

In the meantime the Ikea 11W jobbies do me.

The GU10 replacement ones have 15 LEDs in them. They supposedly consume about 2W and last 50000 hours or so. They do not produce as much light as a 20W bulb, as claimed, but are still much more efficient than incandescent lamps. Search this site for other threads on LED lamps.

Interesting site, Heath Robinson! I'm at the point of replacing my 140W of pond lighting with LEDs because I can't bring myself to use it very often!

Thanks for the info.

The 66 LED ones are extra for "warm white" and "white" - ending up at about £12 when you add the VAT (delivery is free).

I think I'll buy one to try it out. It will probably take several years before it saves me any money, though!
