I swapped almost all the lights in my house to LED last year. They look just like filament bulbs but use one tenth the electricity. Expensive bulbs initially but I've recouped that by now with running cost savings.

Far better than the compact fluorescents in all respects too.

If there is a massive market the price should be down. Light bulb=108 yen. Eco bulb=800 yen. There is a little gap there.

A very good cause, but by God's Holy Trousers, are we not all sick to the back teeth of this one-trick pony by now?

There is being a chancer, and milking it beyond reason.

I've been replacing all our bulbs with LEDs, but as I type, I have one that is flickering on/off, hasn't lasted three months! I guess it's just a bad one, but I'll keep using them until some government does a study saying LEDs cause premature death in tanukis.

I have been replacing old bulbs with LEDs when they crap out, BUT I have had to replace TOO MANY new LEDs that are likely faulty, given their price if quality isn't improved they may not be as cost effective as we are being LED :)  to believe!

There's a reason many of the light bulbs in my house are now LED. First, they use very little power for the amount of light--you get the equivalent of a 60 W incandescent light bulb with only circa 7 watts of power draw. Secondly, they don't generate anywhere near the heat of incandescent bulbs, so that saves on air conditioning in summer. Thirdly, they don't contain even small amounts of poisonous mercury like you have with compact fluorescent bulbs. Finally, LED bulbs are no longer expensive--I can get 60 W equivalent bulbs for around US$2 per bulb at a local retailer, and they last up to 50,000 hours.

By the way, LED lighting is now very popular for street lighting. They use a small fraction of the power consumption of gas-vapor lamps used for street lighting in the past, and the LED color temperature can be "tuned" to also reduce light pollution outside of urban areas, too.

This dude can't disappear fast enough.

More than one year?! I thought the whole point of LEDs was that they last a lot lot longer as well as being much more efficient.

Not sure what Japanese houses you've been to, but my apartment already had the old fashioned bulbs in the bathroom, crapper and above the cooker in the kitchen when I moved in. They're still there but I really should replace them with LED. Then again, I spend most of my time outside, and when indoors, I'm usually in the living room where there are fluorescent lights.

Replacing home lights is a good start, but what I would like to see is the same with street lighting. Tokyo, indeed Japan in general, use a phenomenal amount of street lighting. Unfortunately, most of it is very old, poorly directed, and no doubt using old style lamps. Even new street lamps seem very low-tech to what is readily available and starting to be used overseas. At least if they could focus the light downwards it would be a start, and they could replace bulbs with LEDs whenever the next scheduled maintenance is.

I have never seen a Japanese home with incandescent light bulbs maybe an odd one in a passageway or toilet.

My point being that they not as uncommon as you think. There are 3 in my apartment. At least one in my old apartment.

2 LED's 13W ¥500 and seem to last more than one year with our use.

I'm not sure where you're getting your information from. A quick check on the net says they typically last for 50,000 hours, some double that. That's 6 straight years, non-stop. Oh, just realized Raymond also wrote the same.
