By Sep 2012 new technology LED lamps should be in full production

that's just 3 years but I'd like your optimism to be true!

It's a promise the LED lighting industry has broken for every
one of the last 20 years!

We now have some very viable units in mass production at reasonable
prices. I understand your scepticism, but I do not see 3 years as
being overly optimistic. Right now it would be quite possible to
illuminate your entire house (including garden floodlights) with
commercially available LED lighting.

Do you get a free set of night vision binoculars with every cwt. of
LED lamps ?

Personally I would fit about 20 or so small flush-fitting 5W LED units
into the ceiling of a medium size room. It would provide an
*extremely* bright but glare-free room (when needed) and an even,
shadow-free light. Dimming can be achieved by not having them all
switched on, which also has the advantage of allowing part of the room
to be bright (perhaps for reading) and another part dim (for TV
viewing).

My postcode is LS27 7QZ. Since they are commercially available perhaps
you could indicate the nearest showroom where I can see an "entire
house" lit by such lights.
I'll be there with my light meter.

Pop into Poundland and buy a dozen of their circular camping 20x LED lights,
each use 4 AA cells
During a recent power outage i use 4 of them to light my living room.

Nowhere near enough light for everyday use, but I'm sure a dozen of them
mounted on the ceiling would be.
