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.

If you think something important is being hidden then you had better tell us what it is.
It's your choice. I *think* that switching off some of the lights would be slightly more energy efficient than dimming, and it also allows you to light only the parts of the room that you need to light.
I don't see any numbers there relating to spacecraft and pm per gallon. I don't see any information there, either, that can convert the solid rocket fuel into a 'gallon of fuel' equivalent. Perhaps I am being short sighted.
Yeah, sorry, forgot to pick up on that. You need, really, to consider like for like jobs as well. A ferry is closer to the function of a plane or a train or a car than a cruise ship, carrying accomodation and entertainment with it, is.
Well quite, hence the question. Perhaps a few pointers to what you consider to be the best of breed examples of LED lighting?
Maybe there's a 'category error' here?
I have a substation in my garden and get about 250V on average.

Most car journeys journeys are less than two miles.

Would that be measured in miles per nosebag?

???
If you're carting an entire five star hotel around at the same time, yes.
I wonder what the stats are for a large passenger ferry.
Why slow down if the traffic light is not presented to you?
Dave
You are. A spacecraft can travel forever at millions of miles per hour on no fuel whatsoever. Therefore it must be *potentially* the most fuel efficient method of transport. I chucked it in my post as a semi-humerous observation, but with the serious point that such comparisons are not always a valid way of looking at things.
You made a sarcastic comment, it was not put as a serious question.
I have a vested interest so it would be unfair of me to make any specific recommendations.
Otherwise Dennis would run down the man with the red flag walking in front of him.
Not I, check the attributions.
However *my* question was a genuine one and was intended to be taken seriously.
Why? If you do so in the context of having explained that vested interest. This is usenet after all, bias is tolerated and indeed expected!
My reason for asking, was that inspite of much hype, much (if not all) of the general purpose LED lighting I have seen so far, I not been that impressed with. Often exhibiting low overall brightness levels (but very high directionality), poor colour rendition, and often poor reliability. If there is stuff being made now, or coming on stream soon that is better than what I have experienced so far then it would be nice to know.
Looks like CFLs are now officially dimmer that they claim to be:

Vos Pad was an early complete interior that , personally not entirely sure worked
With great respect, dimming is an essential part of , any modern, interior lighting design.
The great advantage of LED lighting is the ability to exploit putting light exactly where it is required even with the fittings and furniture of the space.
