and someone suggested LED bulbs, which I've not seen before for domestic use - I've only seen compact flourescent (energy savers) and ordinary incandescent bulbs. Anyone used the LED ones? are they good?

Answer 1

They are the coming thing, as someone noted. But they are not really ready for prime time. Sorta like the long long time it took for Compact Flourescent Lightbulbs (CFLs) to finally be reasonable in price and finally small enough to fit most common fixtures. As someone noted, LEDs until recently were not available to produce white light, but that problem was recently solved. But it will still take a few years before a good white light will be available. Most LEDs you see, such as in flashlights, have the blueish light. Same with those annoying bright blue car lights you occasionally see. The beauty of LEDs is that they do not produce any heat, or an insignificant amount and use very little energy. CFLs are much more efficient than incandescents but still produce some heat and use more energy than the LEDS.

Answer 2

I've heard of them, but I have not seen them in the stores yet. I recall a story earlier this year in which they predicted these LED bulbs would take over the market within two years.

What makes these so special, is that no one has ever produced a white LED before. Individual LEDs emit a single frequency (color) of light.

EDIT: I found a source. (Link Below) 60 Lumens seems to be about the limit for a direct replacement bulb. A GE 15 Watt Standard light bulb puts out 110 Lumens.

Let's hope there big improvements in store.

Answer 3

Yes I have 4 of them in my kitchen and although they are good for direct light, they will not light around the room. The flourescent bulbs are better but take some time to warm up.

Answer 4

I used 16 of them in a 6 by 2m bathroom.Had to change them ,they gave off about the same amount of light as a candle.

Answer 5

you need to have asked the police to seek your homestead for drugs because you felt the folk residing at your homestead of residing would have been doing drugs. because you gave them a place to stay, they had something reported as squatters' rights. this suggests you may desire to conflict by civil court to get them kicked out contained in direction of the eviction technique. in case you were waiting to coach the police their drugs, you may have been waiting to get an emergency eviction completed. The police got here on a relatives violence call through fact somebody reported it. You admitted to touching them. that is relatives violence. on an analogous time as $50,000 looks fairly steep, that doesn't rely now. previously pleading to blame, you need to are turning out to be an criminal professional and considered approximately the two getting the cost brushed off or plea bargained. you may't get the project resolved until you end your probation. you're presently in violation of your probation. in case you flow lower back and finished your probation, you may properly be waiting to get the relatives violence cost expunged out of your checklist. in case you do no longer, you will proceed to have that during your checklist.
